Enjoyed it right up to the end (I think?) of mission 3 where it crashed me back to the XO menu. Cost $20 here in NZ, which I think is the upper limit of what something like this is worth, but - so long as the crash thing isn't an ongoing problem - I'm happy enough with it, it is Halo after all, and I'll always choose to play a twin-stick game on a platform with actual sticks!
