Hi-Rez Studios has made Tribes Ascend available to the masses of Steam gamers around the world — and it’s still absolutely free. You can find the game itself and the core functions on Steam now, and can fully enjoy the game without making any purchases. However, if you so please, you can purchase additional upgrades, weapons and packs of content at your discretion.
Steam has a sale going on for Tribes at the moment for the Starter Pack, which will net you two special classes, 12 weapon unlocks, 4 perk unlocks and 400 Tribes Gold, along with a permanent 50 percent XP boost for $10.
This pack will be available until July 4th for $10.
