If you want real world weapons, play Counter-Strike. Gameplay amounts to moving the mouse forwards, stopping, picking up the mouse, laying it back down, and moving it forward again. The controls are some of the worst I have ever used. Reconfiguring them seemed like a waste of time, because the game has nothing to offer anyway. There are no missions objectives, running around until you die is the purpose of Action.
Graphics are a mixed bag.
Can't really deduct points however, as some enjoy this environment. Won't make you say wow, but not fuzzy and cringe inducing. Action half-life is a great mod made by amateurs. In this game, you play the good or the bad guy. Good guys are cops and bad guys are mobs.
