This is one of those 'run as fast as you can and don't get killed' games. And that's exactly what you will be doing.
Quake III Arena has got heart pounding action at every possible moment. The basic strategy behind the game is to kill or be killed while running around 3D levels in a first person perspective. Although this game is awesome at all times, where it really shines is in the multiplayer mode. Up to 4 people can hook it up at once via split-screen. This is the ultimate way to have a fragfest with your buds! Modes of play include Deathmatch, Team Deathmatch, Capture the Flag, and Tournament, and all are a blast!
Speaking of multiplayer, if you aren't connected to the Internet in your home yet, this is the time! Hooking up via modem to SegaNet (or your current ISP) allows you to get it on with players from across the world. In fact, it is said that you can even play against PC Gamers online! This is absolutely amazing and opens up the world of home gaming to endless possibilities. Sega claims that SegaNet will be a dedicated game server (also can be used as an ISP for your computer) which will allow faster gaming speeds, but I connected via my current ISP and gameplay was incredibly smooth with (very little slowdown) as well... and what a blast!!! I would recommend buying yourself a keyboard and mouse as it is much easier to control than the Dreamcast controller (although the DC controller actually does a very nice job). Using the keyboard/mouse combo might just be the extra advantage you need to make pieces outta your opponents, and you will need every advantage you can get!
