ZombiU was a survival horror with a fresh conception, but was not profitable and therefore Ubisoft cancelled their future plans on the franchise. These plans included a sequel which first details have been unveiled by Unseen64:

– Same settings and design than ZombiU 1.

– Development started immediately after the release of ZombiU 1 with a team of 5-10 people. ZombiU 2 never passed the pre-production stage.

– ZombiU 2 would have included cooperative. First player would have played through the Gamepad, the second player would have used the Pro pad. Ubisoft wanted to keep the same tension than the first chapter had, but this time adding a second player. The game would have included different routes.

– New weapons.

– Cancelled.

Thanks, Unseen64.
