Gears of War 2 has been updated before, and a new update is coming up later this month. First up is a revamp of the online experience system, which doesn't really apply to either the campaign or Horde mode. A few tweaks and fixes do apply to co-op, though.
Public Horde has been outpacing almost all of our multiplayer game types. But one of the things that sort of sucked about playing Public Horde was the fact that if the host quit on you after three hours of playing, then your high score never got updated. So one of the things we're doing now is, at the end of each wave, if the score that you have is a new high score for you, then that'll get posted to the leaderboard right away. So if a host quits after three hours, then you know at least that your high score has been saved along the way.
Not a game breaker at all, but still nice to see the Horde mode love. The title update is coming on March 24.
Also of note to Horde mode fans is the announcement of the next map pack. Coming on March 31, the Snowblind map pack will feature 3 new maps, plus a remake of Gears 1 fave Fuel Depo. Soon there will be a few new options for you when it comes to a prime location for fighting the Locust with a pal or four.
