I was going for 3 achievements in Deus Ex: Human Revolution. These were Legend (complete game on hardest difficulty), Pacifist (don't kill anyone but the bosses) and Foxiest of the Hounds (don't set off any alarms). During the game I got a glitch where my paralized enemies suddenly turned out to be dead, even though at first their status said they are sleeping. I also managed to save Malik which was easier than it seemed first, and at that point I was sure that at least one of the achievements I'll not get, but I tried to get them to the end anyways. Yesterday I finished the game and got all 3. Was the most rewarding feeling since I maxed out NFS Most Wanted. Now if there weren't any collectables in the game, I'd probably go for a full score but I don't care as there are collectables..
