“its like Rainbow 6 seige but intruder is better and more has better stealth options”
“Peak, you actually have to use strategy like 90% of the time. Its preferred to have a large friendgroup that owns this game to have the full full experience but 2v2 or 3v2 works too”

— a player, Steam review · 23 hrs played“still has a very very long way to go, but the small community this game has is very friendly and welcoming. 100% worth the 20$ if you can get a few friends to buy it or if you're patient enough to wait for good lobbies to pop up. best dating app i've ever used in my life.”
