Chaos UT is a great mod to leave permanently on in the game. If you are getting bored of UT then this will get you re-addicted. New weapons are one of the many new features with "The Claw" a grenade launching and head crushing gun, the proximity mines (which were used to make my voicepack, DK-ProxyVoices), and second ammo type for the sniper rifle - RPB's (Rocket Propelled Bullets) which are like a railgun. Also you can now deploy turrets which can shoot rockets or plasma balls. If you haven'y got this, you NEED to. You may need Download Accelerator Plus if you have a modem or slow connection.
