I played for about two hours today. It's fun, though not spectacular. Feels a lot like Destiny 2's Gambit game mode (but no buttery-smooth announcer).
I'm not too invested in the story personally. It seems like there's a decent amount of depth here for those who are.
The game really needs per-class tutorials, or at least in-game descriptions of class abilities. I've been paying as the grenade dude and I have no clue what exactly my RB ability does.
There's enough here to keep my interest for a few weekends at minimum. Glad to see it's on Game Pass!
