I've unmasked Jason once. Playing as Buggsy, I was being chased by Jason, had a machete in my hand and was almost out of stamina and couldn't sprint much longer, so since Buggsy has 10/10 strength, I turned on Jason and smacked the fuck out of him with the machete and knocked his mask off in one blow. Picked it up (and got the achievement for picking his mask up) and ran like hell while he was stunned.

Ome game we were so close to killing Jason. We got his mother's sweater and we knocked his mask off, but we must have messed up the order or something when trying to get him on his knees and kill him.
