It seems like the servers are only up midday as this is the only time during the day I've attempted to go online. They never work during the night time but I instantly got in during the day. The online is well done. I'm running at 15mb/s so that might be why, but I didn't notice any lag and it's extremely fun. It's like going to a friends and staying up playing Twisted Metal 2 all day long but better because you're not required to leave your house(as lazy as this sounds.) Unfortunately there's no way to play with friends on the demo, so will have to wait until the full game.
