To the sound of much rejoicing (and possibly some excited squealing from some quarters) we got our hands on the Mass Effect 2 review code. We can't say much, nor would we want to, because from the very first second, ME2 establishes itself as a game that demands to be played with as little prior knowledge as possible. Having said that, we can talk about our playthrough of the first 30 minutes in general terms. No spoilers are contained herein then, unless you thought the game was going to be rubbish.
