The game that made FPS on consoles, now people who didn't play it at the time won't get why it's great (i'm looking at you Klemoib). At the time the controls were fantastic. animations i'd never seen before like the scientists would surrender and you could shoot there butt and they would hold there butt XD And there would be blood were you shot them, i'd never seen that before in a game. And then there's the multiplayer, all my friends and i would play hours upon hours having so much fun. It doesn't look good now but i have so many good memory's playing it and a lot of other gamers do to that's why it popular.
