selaco has the Groovitude. that je ne sans quoi of Groove. it is an inherently Groovy game
also if you enter 0451 into too many keypads you get an in-game email from the devs saying "knock it off we love imsims but this is an FPS with keypads not an 0451 game" lmao
this game suckers you in by making you think "oh it's a FEAR-inspired thing made with GZDoom that's cute"
and then you play it and the stuff that's out in early access is like TEN HOURS of incredibly well done sort-of-tactical-sort-of-retro shooter and you're being blown the fuck away by the sheer quality of it all and also having Halo: ODST flashbacks in the best of ways
