Don't expect too much from this, as it looks like early beta footage and the unfinished parts are clearly evident, but this is the first we've seen from eagerly awaited science fiction RPG Mass Effect 3 so it's better than nothing. If the mechanics here are anything to go on, it seems like not a vast amount has changed from ME2, although the actual gameplay (from 10:30 onwards) is so limited it's really hard to tell. Either way, have a look, tell us what you think…
