I was visiting my sister and @Nossie today. While waiting I played some 'Splosion Man on his Xbox 360. 2 really easy Achievements earned me 20 points, for a total of 300 Gamerscore.
This game reminds me of Cloning Clyde. I suppose this is partly because of the setting, but in general it has a similar feel. Again I like the game, but not as much as the majority of reviewers seem to.
