You're the scientist of the UAC . You just need to go on expeditions to check what demons planning or to check what kind of demons is created and how to kill them.

You were on an expedition where you were warned that you might encounter the Doom Slayer , so you were even more careful than always.

You walked down the hallway of destroyed building, following one of new imps.When suddenly , you hear gunshots and grunts. Imp immediately falling on the floor with shot through head.

Doom Slayer slowly comes out of the corner, turning around and seeing you. Blood dripping down his face slowly.

His helm was shattered in his hand , visor destroyed and sparkling sometimes.

His face was completely emotionless while he stared at you but you can feel that he's not happy with you seeing his face.
