I mentioned earlier this week that No More Heroes 2 would be playable at PAX, and already some gameplay footage is posted. It looks like that between the two videos, the entire PAX demo is covered, although I could be mistaken. It does end in a way that most demos do, “Coming Soon!”, or something along those lines.
You can see part one here, and part two here, as hosted on IGN.com. Be warned, there is the annoying kind of age gate, where you can’t just select 1900 as your birth year from a drop down menu. You can also see the video of Suda himself, sitting on a toilet, over at Joystiq.
We see the ability to switch from one weapon to the next outside of combat, some revised UI elements (wiggling battery monitor?), new enemy types, and even the majority of a boss fight. Judging by the end of that video though, I doubt the fight would continue after that, but it’s No More Heroes, it’s possible.
