Its just not any good
Its not the absolute worst FPS game I have ever played. The play feel of it isn't in itself too bad.
The plot is at best cliched.
The graphics are perhaps on par for a 1998 release game, hard to believe this was released in 2002.
The enemies are a complete mish-mash, and the AI seems pretty poor. The addition of melee combat could have been interesting, if they didn't just run into your gunfire.
It has a stamina counter, which for all evidence seems like they just added it to have something to list as a feature, as it has no real use.
The Bottom Line
If you get the chance to play this game without buying it then go ahead, but unless you are an absolutely rabid collector, this is one to avoid wasting your money on.
