Hellbender

Unreal Tournament 2004
The Hellbender is one of the vehicles that appears in almost every Onslaught map. It looks and drives similar to a Jeep or an SUV, and carries three people, including the driver. If there are vacant seats in the vehicle, any player currently riding can switch to a different seat by pressing the 1, 2, or 3 button.

The Driver
The driver cannot control any of the weapons in this vehicle; he can do nothing more than drive the vehicle and honk the horn to get other people's attention.

The Skymine Turret
The second passenger is in control of the Hellbender's side turret, which shoots Skymines. This weapon works like the Shock Rifle but can be more powerful. The primary fire shoots slow-moving skymines which are similar to the shock rifle's shock cores. However, unlike the shock rifle which can detonate only one shock core at a time, the alternate fire allows all skymines within close proximity to each other to detonate in a chain reaction. This weapon is useful for close-range defense of the Hellbender, powernodes, or objectives.

The Rear Turret
The third passenger is in control of the Hellbender's rear turret. Unlike the side turret, which is designed mostly for close-range defense, this weapon excels at long-distance sniping. Like the Lightning Gun and Sniper Rifle, the player can use the alternate fire to zoom the view in and out. The weapon is fired by holding down the primary fire to charge up the weapon to the desired strength, and then releasing the button. This allows for a trade-off between weapon power and time spent in-between shots.

Unreal Tournament 3
"The Axon Hellbender is the spiritual successor to the High Mobility Multipurpose Wheeled Vehicles of the 20th century.  The upgraded chassis provides strong maneuverability in the field, and the up-armored neutron panels offer moderate protection to the vehicle's occupants. The Hellbender's main strength, however, is its powerful weaponry. The rear turret focusses a devastating bolt of plasma at its target. The frond-mounted shock cannon releases floating mines of unstable plasma which can be chain-ignited by the weapon's secondary photon beam.  It is not uncommon to see a group of enemies devastated by this spectacular weapon, and it should be approached with caution."
