I downloaded it last night, it's awesome. I was worried about it because the previous dlc had broken game mechanics and seem to have been made by someone who never played the original. I know they cut it down for file size reasons but everything about the movements and physics was off. The new one is great though, they added cool extra features like hats and didn't negatively change the gameplay from the original. I <3 the sentry gun. Definitely worth checking out if you played the original.
