Xbox just released on their channel a never before seen short film of the upcoming team-based shooter from Blizzard, Overwatch. The short stars two of the playable heroes, Winston and Reaver.

The short animated film is set in Winston’s lab and delves into his past, showing where he got his start as a young ape. It also brings a bit more clarity to why the heroes of Overwatch are active again.

This is the first of four expected Overwatch shorts.

Overwatch is coming to PC, PS4 and Xbox One May 24th.
