Now what is Tribes 2 you might ask? Well its a crazy fps game that lets you reach incredible speeds with almost zero hitscan weapons (there are 2, and only one is used commonly.)
The rules of the game are simple. CTF is the most common gametype, and the team that captures more flags wins.
A great example of a good Tribes 2 match is probably this one, which is a favorite and considered one of the best.
This match actually didn't come from the tournament, its just a good example of what a tribes 2 match looks like (albeit this one was between two of the very best teams during the prime of the games life a few years ago.) Unfortunately the quality is pretty low, but its a great match and the caster does a good job.
Anyways, back to the tournament. Today, at 10 EST, single elimination starts. A match (most likely my team, but possibly another one) will be casted by 2 or 3 people depending on if they bring someone else in besides their usual partner. If anyone is interested in tuning in just go to http://www.tribescast.com/ at 10 EST.
Edit: Time for shameless plugging. They've started a vote for which match to cast, so go to here http://direct.tribescast.com/choose/ and vote for ow|stubbed toes vs .--. tough turtles (my team)
