That's me got 200/200 on Harm's Way as well now, I was struggling with the 1 shot kill achievement so I lined up a 2nd car using another controller and got it that way. Most dishonourable
That brings my total of completed 360 games to a massive 7. They are Harm's Way, Dash of Distruction, Trivial Pursuit, Lego Indiana Jones, Lego Batman, Smackdown vs Raw 2010 and Legends of Wrestlemania.
Probable the 7 easiest games around! except for Avatar.
