I don't know about you, but I'm really digging the art style chosen for this game. That aside, this game is described as a team-based action game pitting players against each other 5 on 5 MOBA style.
What sets this apart from the rest of the games out there following the same genre? That big, bad Guardian you can summon of course!
The MOBA genre, despite its popularity looks like its been beaten to death with little to almost no innovation. However, 2016 looks like it'll be breathing new life to the genre and Gigantic looks like it'll be leading the charge.
Gigantic will also be available on Windows 10. And I believe you can still sign up for the beta last I checked.
