A sequel to Wii U survival horror title ZombiU is in the prototype phase at Ubisoft.

The project was mentioned by Ubisoft Montpellier's Jean-Philippe Caro on Twitter in response to a fan question.

Ubisoft has since told Eurogamer that the project is yet to be greenlit.

"Our teams are constantly working on creating and developing ideas," said a Ubisoft spokesperson.

"We have nothing further to share at this moment."

ZombiU was the standout launch day release for Nintendo’s console.
