Gamespot has posted their review of Tribes: Vengeance and seem mightily impressed.

Aside from capture the flag, four other multiplayer modes are available, including ball, where each team scores by capturing and throwing a ball into a guarded goal, and rabbit, which is flag keep-away. Fuel is arguably the most interesting mode, where each team must venture into the field and collect fuel canisters for deposit at their base. Each team death subtracts one unit from the team depot, and the first team to a specified unit count wins.

If I had liked the first two games at all, I might get excited.
