Resident evil (2002). [Chris] Part 7 - Wesker's betrayal

In the lab, Wesker began preparations for waking up the Tyrant to kill the remaining S.T.A.R.S. survivors, infecting himself with the mutant virus strain shortly before doing so. He was cornered by his comrades while in the chamber and confessed his role in Umbrella's conspiracy before ordering the Tyrant to attack them. However, T-002 recognized Wesker as a participant in the Tyrant Project, and he stabbed Wesker first, impaling him through the chest before going after the others. Though Wesker was seriously wounded, the virus in his body had succeeded in mutating him to possess impressive regenerative abilities, and he woke up in an empty room.
