Towers against zombies

Hordes of undead got out of the bunker and headed straight down the road to the food warehouses. Stop the zombie invasion and save humanity. Build towers, upgrade them and collect bonuses. The towers will automatically aim at the nearest enemy and shoot, and it will be up to you to make strategic decisions - where to build, which tower to build and what to improve. Try different options to protect yourself from zombies. Do not forget about the bonuses: in difficult times, a fireball or a moderator will help the towers in the fight against enemies. In the end, you will encounter a zombie boss, but you will also defeat him, for the sake of the future of humanity.
