Wow. Been ages since I've played Tribes. Loved them back in the day (and the entire Starsiege series, truthfully). Had no idea they've made a third. Have to remember to check it out.
Edit: WTF. This is the FOURTH Tribes game? Apparently Tribes: Vengeance / Tribes 3 came out in 2004. I never heard of that release. That's a damned shame.
