The Warthog is back with three variations:
Chaingun Warthog- Orignal one
Rocket Warthog- Warthog with rocket launchers on the back
Guass Warthog- High powered guass rifel is mounted on the back it's accuarcy is low when in motion but packs a huge punch.

Scorpion Tank- The tank has been toned down, both movement speed and turrent speen have been decreased. Its cannon also does less damage.

Banshee- Now can perform aerial maneuvers. Press left or right on the thumbstick and the A button cause the Banshee to do a barrel roll.A and down sends the Banshee looping upwards. The B button now lobs Plasma mortars.

Wraith- The convenant Tank is now playable but seems to be a bit overpowered. In the test plays a single man could camp the entire enemy base with it ( it will most likely be toned down a bit).

Ghost- Only thing new is the boost ability.

Boarding: All vehicles are able to be boarded. The tanks are unique in this. Your character will latch onto the side and lob a grenade or two into the drives seat ultimately killing him and leaving the tank all to you.
