Tribes: Ascend follows a lot of norms that most shooters have, but overall, Tribes: Ascend is unlike any other shooter you have ever played. The predominant mechanic in Tribes is the combination of skiing and jetpacking. Most maps, whether they are arena or CTF will start you off on top of a hill. By holding down the space-bar, your character will enter a frictionless state known as skiing. There, they will slide down the hill and pick up enormous speed.
