UPDATE: A Microsoft rep informed TGR that this list may not be "100% accurate", but the full list of Achievements will be available tomorrow morning. Given that the official release is coming right after this supposed leak, it’s probably safe to assume at least some of these achievements are legitimate (such as the already-confirmed "Seriously 2.0") but take it with a grain of salt for now.

With Gears of War 2 on the horizon, many of us have been wondering what in-game actions we can take in order to get Achievements for our homicidal ways. Well, thankfully we can step out of the darkness and into the light, as Destructoid has provided us with a full list of Achievements, along with their descriptions and point values. Be warned, the list has some spoilers, so if you don’t want to ruin any of the supposed more “mature” Gears 2 storyline, you’d best look away now.
