You get around 5 seconds between kills to keep the accolades going, probably they were just killing really slow and it disapereared from kill history. Also, the back pack was probably a santa clause bag. Major GP expense to buy all those weapons. I think the radar is a motion detector, just like HALO (only it has a battery life probably like a 360 radar suit with limited power). The ammo count was probably inverted back then, also the bullets are on burst mode. MP5 burst, is that even in CSS? The reason its a wall, is to prevent spawn camping or sniping, you can snipe base to base if that wasn't a wall.
BTW you know u can get accolades after you die. Like you got a mutli, then killed, then you re live and kill someone, it should be a ultra.
