You've been sided with the Slayer, joining him on missions and doing whatever you could to help. Really you were a side man, getting him ammo and medical kits while he did the main work. Yet even with little work you were cherished by the Slayer which ultimately made for problems.

Now locked up in the depths of hell, stuck the Marauder watching your every move. The only reason you're kept alive is to draw the Slayer closer. The Marauder sits there, watching you as you're locked up.
