Yes, it's a simple Tron lightcycle game. For those who don't know, each player rides in a fast-moving bike that leaves a wall wherever it goes. The bike can only turn 90 degrees, and cannot touch any wall. The objective is to be the last one alive.
Recently, I met up with some friends for LAN gaming. There was Threewave, there was Tribes 2, there was even some co-op Doom on Nightmare (fun stuff). In the end, however, this game managed to take up most of our time.
I've had the game on my HD for ages, but I wanted to see how good it was over a LAN. It ended up being one of the best multiplayer games I've played. The camera is perfect (as long as you don't touch the mouse and use the arrow keys to glance), the visuals are very nice (Hell, did Tron itself look this good?), and the small changes to the standard lightcycle gameplay make all the difference. Being able to gain speed by riding near a wall, grind against walls to "seal" things off, and slow your bike down really add to the game.
