You'd at first expect it to be a mere Smash Clone, but it manages to be unique enough that it's own game entirely. Your skills from Smash won't carry over too well. As opposed to Smash in which you have one constant moveset and an array of generally annoying items, Brawlhalla gives you three rapidly changing movesets with items that are considerably more fair to it's target. That being said, characters are not too terribly unique or memorable. You are more likely to remember them as the fast ninja one, the steampunk girl, and so forth. It still is a beta, so they may flesh out the characters more as we approach a official release.

TL;DR
A very unique take on the platform fighter genre, but don't expect too much in terms of character personality.
