Who need unrealistical stupid cod? Doom is the best fps ever created. even with the 16-bit graphics is still more realistical than cod. Retro games never die!
Good idea, needs more weapons, monsters and more islands of course. but you need to do something with the random spawning of monsters because it's annoying when a monster pops right in your face. and also more realistical graphics.
Unless it has toxic cans on it, which are heavy. So, not that easy at all. :)
