E3 2011: Mass Effect 3 trailer shows in-game footage of Reaper fights and rocket boots
We've already shown you the Mass Effect 3 trailer, but - as seems to be the zeitgeist (thanks, Dead Island trailer from a while ago, for that trend) - a lot of it was CGI. The video above was taken in-game, straight off-screen from EA's press conference (on which you can see our thoughts here and here). There's no reporter-punching, but Shepard does get to sort-of punch a Reaper. Punch him with bullets from a mounted gun.
