Zombie Killtime frames its undead premise as a fast-paced platform shooter built around surviving endless zombie waves. Its action is designed for cooperation: players can team up locally or online, making the game’s central challenge a shared fight rather than a solitary campaign.
Combat leans on variety and escalation. The game lists more than 20 weapons, each with a distinct style, and describes zombies with special abilities, including enemies that shoot back. Alongside the barrage of explosions, players can customize their characters, with options ranging from Santa Claus to an alien. A level editor adds another creative angle, letting players shape experiences and play them online with friends.
The listing also identifies single-player and multiplayer support, but emphasizes four-player co-op as a defining way to tackle the zombie onslaught.
