Remember a year ago you saw the double barrel gun on the desk and the bayonets on the wall. Well they became a real weapon in the game. I noticed a gernade sitting on the table only it didn't look like the only gernade we have. So maybe its a sign of a new gernade to come and maybe the blue means it freezes everything. Don't say no its just decor so fast, like I said the bayonets on the wall used to be decor as well but now there real.
