Oh yeah! Epic Games have announced that next year, possibly to say sorry for the delay, that they will be bringing a multiplayer beta to our screens next year.
Rod Fergusson had always hoped for a beta, but the one thing he wishes for is feedback, so that they can try and improve on things that might not work well. This will be the first, and quite possibly the last (Gears of War 3 being the supposed last in the series) that the game series will have a beta.
There is no word yet on what will be included other than the usual Humans vs Locusts battles, but it could be a possibilty that Beast mode might be implemented into the beta, due to it also being co-op.
Gears of War 3 is set to be released Fall 2011, after being delayed from April 2011.
