It ranges from a rocket launcher and one of the best fps weapons- the almighty rail gun. The single player doesn't bring much satisfaction except blasting brain-less monsters. Basicly this is a multi-player game. I guarantee u will have fun playing it. The game also offers mods which include hook or extra powers contained in runes.
Graphics are great for that kind of time.
The explosions are pretty good and the effects after u fire a rail gun are great too. Sound is not that great but is sufficient to this kind of game. Enemies moan, scream and splatter after being injured or killed. Weapons make good sounds also. Together, Quake II is a winning combination.
