If you played any other familiar games that use idtech2 (SoF, Kingpin, W: RTCW, Q2) then you shouldn't forget about SiN. It is pretty much almost same like in any other 90s FPS shooter. There's nothing like you wouldn't enjoy the gameplay or the weapons, story and such, because I enjoyed it as much as I could and I guarantee to you that you will enjoy it like me, you just have to play it and stop believing in what haters say. Characters are interesting, humorous and they never get boring. Traveling around the world to stop a woman (Mother of Nature, she calls herself..) that leads the evil corporation, SinTek, which is manufacturing disgusting substance. I won't tell much about it since that would be spoilers. Except there are some things that I don't like on this, and that's the rough start when you play the game for the first time. You are trying to change your OpenGL from 3dfx to default or any other ones but the game just forces you for the 3dfx. The resolution change will sometimes break and you will end up in the situation when the game will switch from resolution to resolution, over and over again. Your display will be for seconds black and for seconds normal again until it totally goes black and you have to restart (Turn off) your computer. I also experienced the stuttering, but it faded out soon quickly. Even some missing dialogs are replaced with text dialogs, but you can swear there were sound lines already, they are not just there. Some bugs too, but not too much game-breaking. Saving is must-do too since you can end up being wrecked so quickly without realizing it. Damage points are here too, so you can use your pistol to quickly eliminate your threat by headshot, or you can shoot their hands so they will drop their weapon, same goes for you! So overall, it's not bad how it looks like. The game can be enjoyable like any other old FPS games. It just got quickly overshadowed by its competition, Half-Life. Give it a try. This review was from my view.
