if it had better graffics , more seeable zombies, multiplayer,faster reloading,more weapons,more maps, and u could run a lot quicker(i dont mean actually runing faster i mean a faster way to start runing) it would be so amazing it would be a god of games
switch wepons with e and q and also ur not supposed to start off with so much xp unless u pick experiment mode also u dont use healthpacks till ur dead i give it 5/5 great game
