Epic have shown actual gameplay footage of Gears Of War 3 at E3 2010 event. Previously we had only been able to view a trailer and still images.
In the video, which is over 5 minutes in length, you can see a Locust rip off a downed COG trooper's arm and then beat the poor guy with it! As you would probably expect, the mechanics of the game look look very similar to the previous two installments.
To view the video yourself follow the external link below.
The game is set for release on 5th April 2011 in North America, 7th April in Japan and the 8th Apri in Europe.
