This will simply be an excerpt to showcase the character I will be using in any roleplays. Lemme know what you guys think.

".....the headaches......they kept coming back......" Sam popped a mentat into his mouth with a shaking hand. That was the third time tonight. Ever since he had left that building he had kept having sharp heacaches. "If I had known this would happen, I would have never stepped foot in Dunwold or Dinwiddie or whatever that office building was called." Sam moaned to himself. He checked the battered Nuka Cola clock on his wall: 5 in the morning. "Too late to go back to sleep now." The 22 year-old scavenger rolled off of the beaten mattress he called his bed and slapped a clip into the .32 he kept under his pillow.
Sitting up and fully opening his eyes, Sam looked around the small grocery store he currently called "home." Hearing skittering sounds close by, Sam drew his pistol and entered the bathroom. Inside was a sizeable radroach, or in his case, dinner. "Damn roach!" Sam shouted. 3 sharp cracks rang out, and the roach fell dead. But then his vision blurred, and the insect corpse disappeared. "The hell did it go?" Sam pondered. He reached into his pocket and pulled out another mentat........

So, what do you guy's think?

There does not seem to be enough information to judge what kind of character he is, it is more like the first paragraph of a story.

May I suggest that you lay out more such as his appearance, a solid back story as to how he came to be in the office building, the kind of weapons he is adept with, in fact if you check some of the RP sign ups you will see the kind of bios required.

You will give other members more to comment on and possibly suggest changes.
