After hanging on every word that Epic's Cliff Bleszinski had to say, Kotaku put up a very juicy piece of information for Gears of War fans. Yes, it seems as though achievements that you've unlocked during the first Gear of War will lead to certain perks being unlocked in Gears of War 2.
Even more interesting was the announcement that Gears of War 2 would feature "linked Achievements." In short, goals reached in the original Gears of War will carry over to the sequel, giving the player bonuses. Cliff listed three examples of how linked Achievements will work.
Keep in mind, some may be light spoilers.
• Complete Act One in Gears Of War, unlock a playable Anthony Carmine in Gears of War 2
• Find 10 COG tags in Gears Of War, unlock Minh Young Kim in Gears of War 2
• Kill Raam in Gears Of War, unlock a playable Raam in Gears of War 2
Bleszinski didn't expand much beyond those three linked Achievements, nor did he mention if those unlockables would be limited to either single-player or multiplayer portions of Gears 2.
Kotaku also mentions that Steve Jablonsky (Transformers and Texas Chainsaw Massacre) would be composing the score for the Gears of War film.
