Check out the Direct for the full scoop on what to expect besides what's in the demo!
EDIT: Demo over! I ended up getting a chance to try the last session. What a blast. It's got that "just one more round" feel after every game. I like the focus on spraying ink rather than just getting kills.
Also turns out you could turn off gyro controls in the options during the Weapon Select. Loved having just dual sticks instead of gyros, worked perfectly.
Tried out each of the weapon types:
Charger - Couldn't get a handle on this one. I understand how it works but I guess it's just not my play style. I think I'd need to spend some time with it to get the hang of it.
Roller - My go-to. Paintin' the ink is a blast, as with rolling inklings over
Splattershot & Jr - Seems like the standard/balanced type. I liked playing with the sub weapons more than the weapons themselves.
People already comparing the Roller to Little Mac haha. Weapon is strong but can be dealt with. I got owned by other non-rollers just as much as I was rollin' people over.
This one is gonna be a gooder.
