Warning about game's ranks
I beat the game, never playing multiplayer, and am now 52nd place in the world on the leaderboards. What does this mean for me? I now have only 51 possible people in the world that can help me get the "beat 5 higher classified players" achievement. So it's pretty much impossible because I can't even find a boosting partner to get the rest of the stuff. Basically, if you beat the single player mission it automatically ranks you as "unstoppable" in mutliplayer, for who knows what reason! The achievement is only worth a little bit of points, but the annoying part is 100 points is gained by completing every other achievement. Be warned!
