Titan by name and titan by nature. This new pack is huge. There are 11 new maps for Deathmatch, CTF, Vehicle CTF and Warfare game modes. There is also a further eight maps stripped from the first UT3 map pack and the Xbox 360 exclusive pack.

Also included are two new game modes - Greed mode which is a "'tug of war' style kill points battle" and Betrayal mode where players can change teams freely to shift the balance of play.

The Titan pack adds 57 awards which will implement themselves as Steam Achievements on PC and Trophies on PS3 so now you can keep track of just how good you really are.

New field equipment has also been added. The Link Station is a piece of kit that allows you to repair damaged vehicles, and the X-Ray is a deployable field that weakens enemies inside it. There is also a new vehicle called the Stealthbender which combines the X-Ray and Link Station with Necris stealth technology for those surprise attacks.

There is more and screenshots too... 

The Titan Mutator boost has been added which turns players into 15-foot tall killing machines when they rack up enough kills. This applies every power-up to the player in one go allowing for more carnage than ever before.

There are two new characters, Nova and Kana, added to the roster of guns for hire.

Finally, there are two new turret types added. The Eradicator is a stationary artillery piece that can rain fiery death almost anywhere on the map. The Stinger has the highest rate of fire amongst all of UT3's weapons and also the most punishing knockback.

All this is available for free on March 5th for PC and PS3. Below are shots of two of the new maps.
