Gears of War 2 Title Update 3

* New experience-based ranking system: The new system gives you 100 levels of player experience, gained through scoring in Public matches. The game still uses TrueSkill to set up the most competitive matches possible, but skill ranks are now hidden. Players who quit matches early see their experience docked as a penalty.
* Public Match autobalancing: Bots now automatically join a Public Match to fill any slots left vacant by players who quit early or disconnect.
* Improvements: You get region preference for matchmaking, improved standby detection, playlist optimization, plus nine new achievements—six of which require the Snowblind Map Pack—worth a total of 250 points.
* Exploit fixes: Title Update 3 eliminates the ability to mantle greater distances by swapping weapons during cover slide and to melee attack through walls while holding an enemy weapon, plus adding many more fixes.
* General fixes: These include more reliable chainsaw interruption detection, improved headshot detection for certain character model heads, improved flag AI in Submission games, plus other fixes.
* Balancing: Title Update 3 makes changes to Subway weapon spawns for greater balance, reductions to smoke-grenade stun duration, an increase to the forward angle that triggers chainsaw duels, and several other balance revisions.
