Co-Op Endless is the eleventh and the last level in Co-op Mode which takes place in the Pool. It is only available on the Xbox Live Arcade and PlayStation Network versions of the game. It's almost the same as Survival: Endless, but the players only have a total of eight seed slots split into four seed slots each.

Trivia[]
- Unlike Survival: Endless, the players cannot save their game, meaning they will have to start again if they leave this mode.
- Like Survival: Endless, Zombie Bobsled Teams never appear, although Zombonis leave an ice trail.
- In this mode and normal Survival: Endless console version, Dancing Zombies and Backup Dancers are bigger than any other zombie (Excepting already big zombies, like Gargantuar).
- It's also the second Survival: Endless version to have Trash Can Zombie in it, the first being the normal Survival: Endless console version.
- Unlike other versions, even if you bought more seed slots in Crazy Dave's Twiddydinkies, you are still with 8 seed slots when playing.
