  • story914 mentions

    The story in the game has received mixed reviews, with many players finding it generic and lacking depth. The dialogue is often described as verbose and poorly translated, leading to a tedious experience that can detract from the gameplay. While some appreciate the potential for lore and character development, the overall consensus is that the story feels like an afterthought, primarily serving as a backdrop for the mech customization and combat mechanics.

    • “The story is compelling, but the translation could use work, though it is early access so maybe they'll do another pass before full release, maybe get a native English speaker to tweak things.”
    • “The story is decent and the action is fun, especially after you begin fighting other mechs.”
    • “The story is currently limited to 7 missions, however missions can get difficulty in some of the later missions, with more missions being planned currently.”
    • “The story is generic and its presentation so awful, it is unbearable, which is rare even in bad games.”
    • “The story is lengthy and forgettable.”
    • “The writing in the story segment could use a bit of love; the style is very simplistic and could use some more flair.”
  • gameplay557 mentions

    The gameplay of this mech customization game is a mixed bag, with many players praising the extensive customization options while criticizing the combat mechanics as repetitive and lacking depth. While the fast-paced hack-and-slash style can be enjoyable, it often devolves into a grind with bullet sponge enemies and clunky controls, leading to a sense of tedium. Overall, the game shows potential for improvement, particularly in gameplay mechanics, but currently, it primarily appeals to those who prioritize mech building over engaging combat.

    • “Despite the low story rating, some issues with quality of life improvements, not the best level design, this game gets a solid recommendation simply because it's primarily focused on the mech building which is extremely the best and well developed part of this game and gameplay is fun enough to see your mech build destroy enemies with custom weapons, swords, axes, scythes, rifles, blasters, missiles, lasers, and more...”
    • “The gameplay loop revolves around going out to fight missions where you kill various types of enemies, and then spending your earned money on one of three non-cosmetic equippable statblock slots, which each have multiple upgrade trees.”
    • “The gameplay is fast... extremely fast... I feel like a ninja cutting through hordes and hordes of enemies, and everything you have of weapon on your mecha can be used... they aren't just for show... slug shooters, energy weaponry, missiles, shields, blunt objects... you name it... your mecha can wield and use on the field.”
    • “The gameplay is quite clunky still while it's still being polished.”
    • “The gameplay is pretty boring unfortunately and since you have to play the game to unlock more customization... it kinda sucks...”
    • “Gameplay needs work and the camera is hard to wield.”
  • grinding157 mentions

    The grinding aspect of the game is a significant point of contention among players, with many describing it as excessively tedious and repetitive. While some enjoy the process of grinding for customization and upgrades, others find it frustrating due to uninspired combat and a lack of diverse content, leading to a gameplay loop that can feel like a chore. Overall, the game offers deep customization options, but the grind required to unlock parts and upgrades can detract from the overall enjoyment for many players.

    • “If you're not grinding for armor and weapon blueprints, you are stacking up materials and credits to buy mods.”
    • “You'll need a second life for grinding.”
    • “The grinding process and the combat are repetitive and boring.”
    • “Uninspired enemies, weak sound design, and dull combat mixed together in a grindy repetitive mission structure and it's just not a good time.”
    • “The gameplay, which can already feel repetitive at times, becomes incredibly tedious due to the insane grinding you have to do to unlock the cooler parts for building.”
  • graphics154 mentions

    The graphics in the game have received widespread acclaim for their vibrant and aesthetically pleasing design, particularly in the rendering of mechs and the extensive customization options available. Players appreciate the stylized visuals that maintain a consistent art style, although some have noted performance issues that can lead to overheating on certain hardware. Overall, the graphics are considered a strong point of the game, enhancing the overall experience despite some minor critiques regarding enemy designs and brightness levels.

    • “Graphics-wise, I love the rendering of the mechs; they don't look too cartoony, and the mechs look great with a variety of decals and custom paints.”
    • “The graphics are easy on the eyes, and the customization of the mechs is surprisingly involved with how much you can mix and match.”
    • “Absolute amazing graphics, lots of customization options with more to come.”
    • “The graphics are pretty basic right now, but your mech looks fantastic.”
    • “I have a pretty powerful laptop, but even at the lowest graphic settings, I'm still getting poor frames.”
    • “It seems to tax my RTX 2060 way harder than other games with similar levels of graphical detail and it's not obvious why.”
  • optimization67 mentions

    The optimization of the game has received mixed reviews, with some players experiencing significant performance issues, particularly during customization and certain missions, leading to low frame rates and crashes. Others report smooth gameplay and commend the deep customization options that allow for aesthetic choices without impacting performance. Overall, while some users appreciate the game's design and potential, many are awaiting further optimizations to enhance stability and performance.

    • “The mech customization has an almost intimidating level of detail at first, but the cosmetic aspect can be ignored or explored to your satisfaction with no detriment to your mech's performance.”
    • “The performance customization comes from tuning your mech, where you choose different enhancements that can improve fuel efficiency, acceleration, ranged/melee damage, so you have a lot of flexibility in the playstyle.”
    • “The amount of customization options are nothing short of amazing, and I really like how you can make the mech your own with no penalty to performance.”
    • “Poorly optimized, I'd say. My rig can run AC6 on high at FOS, but on anything other than the lowest, this game chugs.”
    • “The latest update has a critical game-crashing bug, and I can't play any missions. I can definitely see the performance of the game drop significantly, judging by the photograph feature because it takes much longer to load the mech.”
    • “There is constant FPS drops and performance issues, and something about the gameplay feels very stale.”
  • music39 mentions

    The music in the game has received mixed reviews, with some players finding it catchy and suitable for the gameplay, while others describe it as generic and forgettable. Although the soundtrack has its moments, particularly in specific areas, many users suggest it lacks variety and can become repetitive over time. Overall, while the music is not considered offensive, it does not leave a lasting impression, leading some players to prefer listening to their own music instead.

    • “However, the soundtrack is pretty damn awesome; I just wish we could get it separately from the game.”
    • “The character customization is top-notch, the music is sweet (especially in the mech setup screens), and the combat is solid.”
    • “Although not the most memorable thing I've ever listened to, the music can be quite catchy... some fields have some really well-done tunes that I might add to my music collection.”
    • “Sound and music - abhorrent.”
    • “The music in the menus also comes across as rather generic, stylistically 'techy', but otherwise lacking in substance.”
    • “The backdrop music will get tiring after a while, but what really gets my goat is the sheer lack of sound variety when playing.”
  • stability16 mentions

    Overall, the game's stability is a mixed bag, with some players reporting minor glitches and bugs, particularly with certain attacks and animations, while others have experienced a smooth and playable experience without significant issues. As it is still in early access, users should expect some instability, but many find it to be relatively solid and improving with updates. Performance varies based on individual hardware, with some players encountering no problems at all.

    • “It's already very playable and not very buggy at all, and it's only getting better with every update.”
    • “I have had no buggy issues playing solo during this early access.”
    • “It does run very well and I encountered no glitches, so there is that.”
    • “The first boss seems to have a buggy interaction with the laser shoulder attack (the weapon's high-pitched shooting sound kept playing) and after a ground pound hit me, I was stuck to the floor and flying wouldn't let me move.”
    • “I like mechas, but the UI is sometimes buggy where I can't click/select anything.”
    • “Since it's early access, expect a lot of bugs and weird glitches that occur while playing in all the different maps.”
  • monetization13 mentions

    The monetization aspect of the game has received mixed reviews, with many players appreciating the absence of microtransactions, allowing all content to be unlocked through regular gameplay. However, concerns have been raised about manipulative mechanics reminiscent of mobile games, as well as deceptive advertising that suggests a more polished experience than what is delivered. Overall, while the lack of microtransactions is a significant positive, players feel the game may still exhibit signs of a cash grab through its design and mechanics.

    • “Endless customization and it seems to not have microtransactions.”
    • “There are no microtransactions in the game; everything can be unlocked through normal gameplay. Though I would suggest one thing to the devs for the hunting missions: you could randomize the enemies in the missions as players unlock new enemies as they play, to keep things interesting when replaying the hunting missions.”
    • “No microtransactions is a huge plus for what the game offers.”
    • “Why this is even a feature seems to be rooted in adopting manipulative loot mechanics from microtransaction-based mobile games without understanding why they were even there to begin with.”
    • “The advertising is, in my opinion, deceptive.”
    • “I put about 5 hours into this game and had a blast putting together my own mech, but there are soooo many unfinished/lazy elements that make this look like a quick cash grab.”
  • replayability13 mentions

    Overall, the game's replayability is highly regarded, with players enjoying the extensive customization options and the challenge of tackling higher difficulty missions for better rewards. While some find the story mode forgettable, the engaging combat and variety of missions keep players coming back for more, with many rating replayability between 6/10 to 10/10. However, some players express concerns about balance and the need for more rewarding challenges to enhance the replay experience.

    • “Very much worth your time; the fighting is smooth and only a very small amount of bugs. I have had loads of fun blasting and cleaving enemies with weapons I created, rather than hoping for a chance at a godroll drop. The customization options kept me engaged for hours, and I can't wait for the multiplayer to come out, as I hope there is lots to do with it being replayable.”
    • “Whilst the story is about average, the gameplay is fun and highly replayable. The overall customization alone can keep one's attention for hours on end and leave one feeling very satisfied.”
    • “It's fast, fun, and has excellent replayability.”
    • “So, the game's replayability is designed around a bit of grinding, enabling you to tackle the higher difficulty versions of each mission and gain greater rewards.”
    • “I was sitting in the boss fight for like 15 minutes and I'm basically stuck until I get better weapons, which doesn't really motivate replayability. There should be more payoff for challenges.”
    • “At the time of this review, there are 10 replayable missions in the 'full' game (including the tutorial), 3 levels of tech upgrades (with different paths), and dozens of cosmetic blueprints to unlock; the demo has 2 missions and more limited upgrades.”
  • character development9 mentions

    Character development in the game has received mixed reviews, with some praising the unique and appealing character designs, particularly in the anime style, while others criticize the dialogue and depth of the characters. Although there are improvements noted in character design, the overall execution of character interactions and development seems to lack immersion and complexity, leading to a perception of superficiality.

    • “The gameplay, combat, sound, story, character design, and progression is ambitious.”
    • “They also really improved the character designs.”
    • “The art style and character design is somewhat unique and pleasing to look at, from the NPCs to the main characters.”
    • “How is the dialogue and character design still this bad?”
    • “There are clearly some cheesy dialogue elements that point toward some of the girls liking the commander, and with the somewhat generically done character designs, you'd be hard pressed to say they weren't eye candy.”
    • “The gameplay, combat, sound, story, character design, and progression is... ambitious.”
  • emotional7 mentions

    Players express a lack of emotional investment in the game's story and characters, feeling that it falls short of the depth typically found in anime. While the customization options for mechs are praised, the emotional impact is diminished by confusing mechanics and a need for more cutscenes to enhance narrative engagement and showcase player designs. Overall, the game could benefit from improved storytelling and musical elements to elevate its emotional resonance.

    • “Story: still in the works, but so far I'm not getting the emotional investment that most anime types have.”
    • “More varied and memorable enemies and better musical scores to highlight tense situations and increase emotional impact.”
    • “The way the gameplay is presented, you can't see the cool decals anyway; more cut scenes are needed to give more emotional content to the game levels.”
    • “The story felt incredibly boring and failed to evoke any emotional response.”
    • “Conversations in the game were dull and lacked depth, making it hard to connect emotionally.”
    • “I found the narrative to be unengaging, which left me feeling indifferent rather than emotionally invested.”
  • humor7 mentions

    The humor in the game is a mixed bag; while some character interactions and absurd elements, like the "hilariously unnecessary anime titties," provide laughs, other aspects feel lost in translation or nonsensical. Overall, players find moments of genuine humor amidst a generic story, though the comedic effectiveness varies significantly.

    • “Oh, the gameplay is fun too! The funny robot goo woosh with a big sword makes me feel like Gundam.”
    • “I find the character interactions quite funny at times, though it is hard to tell what is trying to be said sometimes.”
    • “That's hilarious since ranged weapons are really the only thing you can build that actually changes how the game is played.”
    • “The humor falls flat and often feels forced, making it hard to enjoy the game.”
    • “I expected more laughs, but the jokes are stale and predictable.”
    • “The attempts at humor are cringeworthy and detract from the overall experience.”
  • atmosphere1 mentions

    The atmosphere in the game is characterized by limitations on mobility, as even heavily equipped units like Gundams are unable to function effectively within planetary atmospheres, adding a layer of realism and challenge to gameplay.

    • “The atmosphere feels lifeless and uninspired, making exploration a chore rather than an adventure.”
    • “Despite the game's potential, the atmosphere is flat and fails to immerse players in its world.”
    • “The lack of environmental detail and sound design leaves the atmosphere feeling empty and uninviting.”
