Or that same order but instead of the rifle is a shotgun. But you can buy stuff. You can buy weapons, armor, but remember you can only use 3 weapons. Most are pretty big, forcing you to walk down complex hallways in order to get back in the game. Watch out when rushing down stairs, its easy to fall off.
Some maps are alittle dark, so seeing people it alittle hard.
What also adds to this is that the players are dressed in black. You will walk straight passed some off them. But the players are wearing urban fatigues, look for the black, white, and gray.
