Portal 2

One of the most anticipated game releases of 2011 arrived this week. Portal 2 is the thinking-man’s first person shooter. If you played the original, then you don’t need to be convinced that this is one of the best games of all time. If you haven’t played the original, then you may want to try that first, as playing Portal 2 first would spoil some of the fun of discovery. You can get both from the Mac Steam application.
In both games you solve levels by jumping through portals, moving boxes, making clever jumps and throwing switches. And at the end of the original Portal, you get cake. Maybe.
