This great shoot-em-up game features 16 different types of weapons. There are about 33 maps, which can be played in any order. No, the graphics are not as great as a game that you might find at the store, but each map has great detail and is highly realistic. The size of the game is small for a 3D game with so many options, so I would recommend downloading it.
Some people have problems running the game, so here are the instructions:
1. Unzip the file.
2. Run config4xops04.exe, and press 'Save'.
3. Run xops090.exe to start the game!
