Ubisoft dropped the teaser trailer for Rainbow Six Vegas 2 during the recent Spike TV Video Game Awards show. Although the trailer didn't show a whole lot (or any) gameplay, just the fact that the development is far enough along to be able to release a trailer is exciting (see: Duke Nukem Forever).

Here's that trailer again in case you missed it:
 

Today, Ubisoft released some details on how R6V2 (not a droid) will work. The biggest new addition is the incorporation of an RPG-style experience system, in which you will create a character, and gain experience points through various combat missions/achievements. If that sounds familiar to you, that's probably because you've played the multi-player modes on Call of Duty 4: Modern Warfare.

The wrinkle for R6V2 is that your character will earn experience from any mission you undertake; solo or multi-player. Ubisoft also promises an improved co-op system, as well as more challenging AI.

The full details from their release:

Product Highlights:
• More Multiplayer – The highly acclaimed multiplayer mode in Tom Clancy’s Rainbow Six Vegas has been upgraded to include 13 new maps with more intense face-offs, two new adversarial modes, more rewards, and easier access to matches using the improved and intuitive matchmaking system.

• Unprecedented Customizable Experience – Create your own identity that persists through both the single player and multiplayer modes and progresses along with you. Reap the benefits of your single player rewards in multiplayer and vice versa.

• Vastly Improved Co-op Mode – Turn single player mode into co-op mode at any time, just by jumping into the game. Now you and a friend can jump into a single player game and assist without any change to the story. The single player maps and storyline were created with co-op in mind, meaning every map has multiple entry points and the story is unaffected.

• Challenging AI – The AI is more challenging than ever. Now, the terrorists are equipped with thermal vision, night vision, and shields – not to mention a multitude of varying tactics – all of which are guaranteed to give you a new playing experience every time you go into battle. As you progress within the game, you’ll be able to outsmart your enemies by taking advantage of intelligence opportunities, such as thermal scanning.

• New Weapons and Armor – Take down the terrorists more effectively using 11 new weapons. New camouflage, clothing and gear allow for the ultimate customizations.

• More Vegas – Sin City is back and bigger than before. Explore all new Vegas hot spots and the gritty back streets creating a visual experience that is as challenging as it is breathtaking.

Look for Rainbow Six Vegas Two in March of 2008.
