Tribes is kinda like CounterStrike in a way. It's an online only team vs. team game. But it is futuristic, with lasers, hovercraft, force fields and jet backpacks. There are several different classes of soldiers just like Team Fortress. And there are objectives/bases to capture, conquer or defend. The terrains are huge, miles upon miles in virtual space.
Tribes 2 comes out at the end of the month... finally! They've been beta testing for the past 6+ months. It has officially gone gold. It has everything Tribes 1 had and more! Multiple air vehicles, hover craft and various wheeled vehicles and tanks. The terrains look great, and they upped the poly count on the soldiers too. And they added an alien race. Just more, better, faster!!!
I'm not going to be getting any animations done for about a month when it hits the store shelves.
