Gears of War 3 is a great game. It improves on Gears of War 2 in every gameplay sense possible and the storytelling is improved as well. It's not perfect, and it takes a bit too long to fight against the locusts in campaign mode, but its still the best in the trilogy. That said, I found a minor glitch in the middle of my Insane playthrough. It's nothing major, in fact this happens in lots of modern games, but I still think it was funny. Here are the pictures.
Yup, when I hopped onto the forklift, Marcus stood straight up, standing on air.When I sidestepped, Marcus turned almost 90 degrees in the direction I was facing. Nothing else really happened and the game still saved properly. AWESOME!
