The object of the game, obviously, is to rack up more skull-captures, and therefore more frags, than the other team. Harvester is fun but can be stressful, especially when you have a bunch of skulls and are about to die. Finally, Overload involves infiltrating the enemy base where an orb can be found. This orb has 2500 hit points which regenerate fairly rapidly. Each time your team chews threw all 2500 points it receives a point.
Overload is exciting and requires a good balance of offense and defense.
Kamikaze, once activated, creates a massive explosion that shakes the whole level and gibs you and anyone within its massive blast radius. If you die before you can unleash the explosion, it will automatically detonate after 15 seconds. The nail gun is reintroduced in Team Arena, except it's nothing like the old nail gun or super nail gun. Instead, it fires a large cluster of nails at once, similar to the shotgun. The chain gun is without a doubt the coolest new weapon.
