Zombie Rush

Description
Zombie Rush is a horde survival game similar to Vampire Survivors. Survive against waves of increasingly dangerous zombies. Your player character attacks nearby zombies automatically. Killed zombies drop gems that fill up the experience bar and, once it is full, you level up and get a choice of three perk upgrades, which include both offensive and defensive upgrades.
In-between game rounds you can buy permanent upgrades using resources collected during rounds.
The game can be played co-operatively with two players. In multiplayer, both players share the same experience bar.
