- “The variety of structures and upgrades keeps the gameplay fresh, allowing for creativity in fortifying your base.”

Overall, the game's optimization has received mixed reviews; while some players report smooth performance even on older hardware, many others experience significant performance dips and bugs, particularly during intense gameplay moments. There is a consensus that the game requires further optimization to enhance the overall experience, especially in multiplayer modes. Despite these issues, players appreciate the game's unique blend of mechanics and acknowledge the challenges faced by a small development team.
- “I haven't had any of the performance issues people complain about, and I run a 5-year-old mid-tier laptop that was pretty good back in the day but isn't close to top tier nowadays.”
- “While Ultimate Zombie Defense does have some performance issues and bugs, the fact that such a small development team created a first-person tower defense survival game is quite an achievement.”
- “The only performance issue I've come across so far is when using the freeze gun with large groups of zombies on the map; it caused a few big FPS drops a couple of times while CPU and GPU usage stayed well below 100%.”
- “The game is a lot of fun and has elements of Killing Floor, Call of Duty Zombies, and base building and defense; however, it needs to be heavily optimized.”
- “No matter your PC's specs, this game will have massive performance dips.”
- “The optimization of this game is terribly bad.”

The graphics of the game receive mixed reviews, with some praising the polished visuals and art style reminiscent of classic titles, while others criticize the low-quality textures and models compared to older games. Despite the visual shortcomings, many players emphasize that the engaging content and gameplay can outweigh graphical concerns, appealing to those who prioritize gameplay over aesthetics. Overall, the graphics are seen as a step up from the predecessor but not without notable flaws.
- “Building upon the foundation of its predecessor, this sequel amps up the intensity with improved visuals, a broader variety of enemies, and deeper strategic elements.”
- “+ graphics and map overhaul are great as opposed to uzd 1”
- “Great looking graphics”
- “To start with, the graphics are probably worse than in Half-Life 2 (which is 20 years old).”
- “It feels like they left the graphics from the previous part of the game but now you're looking at those mushy textures and low poly models up close since it's a first-person shooter.”
- “Graphics aren't the best, but if you're like me and couldn't care less for graphics, you'll love it. I personally could play a game with the graphics of Doom 2 and I'd love it, as long as the content is great.”
