Different difficulty, weapons, upgrades and 2 stages. Seems like NT are trying hard to show this game off as best they can. Good
I was impressed by Konami's MGR demo, which was a game I stopped following early on until this demo renewed my interest. But as fun as it was, it was way short and not really so many enemies to fight to see what Raiden can do.
Haven't been too impressed with anything in this game either aside from nice looking backgrounds. Hopefully, this demo is more impressive then the MGR demo(which was still good btw) --- I'll eat a sock if VersusXIII is actually a mind blowing game. -PainsPerception
