Just got subsatnce on Xbox, terribly slow, you would not believe it, its like half the speed of the ps2 version
Aint played much main story wise, but was playing the VR training, its great, training in weapons (including unarmed) sneaking and something else I think. Also theres alternate missions e.g bomb diffusal (looks like the fatman fight) and one you have to kill as many guards as possible. I'll post more as I play it..
