You get a job in the Task Force 141! You started to train, which first was shooting some targets. You saw some stations away this cold soldier, with a skull on his face staring you down.

It must've been because you were new to this base. 20 minutes later, you go into the change room to change for bed. The soldier walked in. You saw his name is Ghost; you saw it on the barrel of his gun.

"Take it off."
