The gameplay combines tower defense and zombie survival mechanics with building and trap systems that offer satisfying strategic depth and creativity.

- “Building and trap mechanics are fun, especially when trying to create funnels to control zombies.”
- “The game captures the essence of classic tower defense gameplay while injecting enough new content and challenges to keep both newcomers and seasoned players engaged for hours on end.”
- “The variety of structures and upgrades keeps the gameplay fresh, allowing for creativity in fortifying your base.”

The game's graphics receive mixed feedback: while some users praise the improved visuals, polished art style, and map overhaul that enhance immersion and strategic gameplay, others find the textures low-quality and models outdated compared to older titles like Half-Life 2. Overall, the graphics may not impress everyone but are sufficient for fans prioritizing gameplay and content.
- “+ graphics and map overhaul are great as opposed to uzd 1”
- “Great looking graphics”
- “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.”
- “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 FPS.”
- “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.”

Optimization for the game is mixed, with some players experiencing smooth performance even on older hardware, while others report significant frame drops and performance dips regardless of system specs. The game could benefit from more consistent optimization, especially in multiplayer and during intense moments, though its achievements are notable given the small development team. Overall, improvements in quality-of-life and audio performance are also needed.
- “(Only died because I was being stupid, otherwise I would have probably exceeded 150.) 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.”
- “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%.”
- “While Ultimate Zombie Defence does have some performance issues and bugs, the fact that such a small development team created a first person tower defence survival game is quite an achievement.”
- “No matter your PC's specs, this game will have massive performance dips.”
- “The optimization of this game is terribly bad.”
- “The game is a lot of fun with elements of Killing Floor, CoD Zombies, and base building and defense; however, it needs to be heavily optimized.”

- “The replayability factor is massive when you consider all the different spots you can use to set up base.”
- “Ultimate Zombie Defense 2 also offers a range of game modes and challenges, adding significant replay value.”
- “The game offers significant replay value with multiple game modes, dozens of upgradeable weapons, perks and traps, and a full upgrade tree for three character classes.”
- “I got around 8 hours of fun out of it, and while I enjoyed my time, it does feel like a 'play it and move on' kind of game due to limited replay value.”

- “Too glitchy right now. Way too many things glitch, which just takes the fun out of it for me.”
- “The cemetery is also bugged where the crypts for the teacher (read on the tombstone wall) are hollow, and you can just walk into them and be mostly invincible, causing pile-up glitches.”

grinding

Players find the grinding in this strategy round farming game tedious and morale-draining, especially during specific rounds with fire dog enemies. The focus on farming for perks detracts from the overall enjoyment, making the experience feel repetitive rather than challenging.
- “Rounds with the fire dog things (5, 15, 25 etc.) are tedious and morale destroying, but not hard.”
- “It's not very enjoyable because the gameplay is now tied to farming for perks.”
