I swung the assault rifle over my shoulder and grabbed the sniper rifle. I repositioned myself and the sniper rifle to face the door wherein about a couple of seconds, humanoids will be in sight. Since I had a couple of seconds, I put on a duel handgun thigh holster and put two beauties in.
I also strapped on a couple of magazines in case I manage to get out of here alive and need to reload later. Laying down on my back, I put the sniper rifle over me and pointed it up. Come on assholes, I don't have all day.
With a big yank off the hinges, the door flew away and a lovely humanoid head popped up into view. I blasted its face-off with my enhanced sniper rifle. The head of the humanoid disappeared and a new one came into view.
Three headshots later, I waited a few moments and decided that I shot up all the humanoids that knew I was in here. Just to be safe, I used big bertha's eye to look around my surroundings. It seems to be all clear.
