Not like the first one had one but Epic
has confirmed to Shacknews that there won't be a demo of
Gears of War 2 before its release. I'm sure that's not going to deter millions of people picking up the game on release day and to be honest it's not like a game like this needs one. You pretty much know what you're going to get and it's rare a AAA title does release a demo for consoles.
