One of the best multiplayer FPS.

User Rating: 9.6 | Delta Force 2 PC
Despite the glitchyish graphics, this game is amazing. You can play either single or multiplayer, which of course multiplayer is best. You can create your own maps and host them to show them off, or you can simply join another game while going through a varity of many types: deathmatch, king of the hill, capture the flag, team deathmatch, search and destroy, and more. There isn't too much lag surprisingly in the multiplayer game at all, unless there's several explosions and lots of gunfire going off at once. As far as single player goes, there's two campaigns full of missions along with several quick missions. You can also use the mapmaker to create your own single player missions. You can do pretty much edit whatever you want like the enemys' AI, the fog levels, anything.

This is by far one you'll have fun with if you're a FPS fan, or just getting started with the FPS genre. Go for it, I highly recommend it. You'll probablly spend hours online with it. Also, the reason I chose 100 or more hours is because the combonations are endless. You can make new maps, play online on new or known maps for however long you want!
