- good evolution of lets build mechanics -increased difficulty as the tech tree requires points which changes the strategy from your previous lets build map -adds creativity to the barricade system and allows the player to freely choose how to construct their defenses

-large empty space between the fuel system and generator/tech tree -it is difficult to keep up with the hordes as they become larger the bots struggle to keep up even if you supply weapons, first aid kits etc. -some tech tree items are overpriced such as first aid kits and defibrillators as it is so difficult to bring fuel cans to the generator -bugs include special infected not spawning for long periods of time; barricades are buggy and it is sometimes possible for the player to pick up multiple items which interferes with their placements; recycle bin sometimes fails to recycle; objects often get stuck in ground rendering them useless as you cannot recycle nor place them.
