Here you can see a random keyhunt game with 2 bots on Fruitex retextured stormkeep. Keyhunt can be played with up to 4 teams and your goal is to bring all keys together.
You also can see the new miniradar. Also another feature which works in CTF, Keyhunt and Onslaught, is the health indicator.
The Weapon you see here is the new Heavy Assault Laser Cannon (short HALC). The primary fire is like the plasma rifle from q3 and the secondary works like the Falk cannon from UT. Its a ideal weapon against rocketlaumchers and to finish of enemies with low health.
