In Gears of War 2 news, the people of Epic seem to really understand their audience. Epic loves us for exactly what we are, a bunch of achievement whores. Now while some people may be above spending time going through games solely to raise their gamer score, most of us are not. Epic has created a whole new type of achievement system, called “linked” achievements.
Linked Achievements occur when someone obtains an achievement in the first game(Gears of War), this then unlocks new content in the second game(Gears of War 2). Some examples of this are:
– 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
