Exanima
Unique physics-based isometric dungeon crawler also featuring an arena career mode.
Moddable.
Really slow development cycle, though.
Severed Steel
Futuristic 3D shooter with maybe the best movement system I’ve tried, with wall running, full 360 air movement, sliding and more.
Weapons have only one magazine, so you’re constantly sourcing them from your enemies while blasting holes into the fully destructible levels.
Very replayable.
Yeah, wtf, asking for story yet missing the point in Doom which has the simplest story of them all: demons are bad and you need to kill them to save humanity.
I can’t really help with the topic since I don’t care for story in my shooty-shooty boom booms and prefer to get into action as soon as possible and keep at it, but I guess the Far Cry series has some story in it. Maybe skip the first one since controller support might be iffy. Also Crysis, don’t know about the latter ones but first one is great until a certain point after which it’s okay.

Oh man I’m so sad shitty streamer culture and the toxicity it brought killed Sub Rosa. Played it a ton while it was still on version 0.07b and even more niche, later when the “world” mode was introduced and which got more popular than round mode it went downhill steadily with obnoxious players becoming the norm.
Apparently Revolver Digital pushing for updates from a one man team didn’t help, either. I really hope CrypticSea will continue the game at some point but that seems unlikely. A truly unique game.
E: Also Intruder, which I’m not sure is still alive but might have some active community. Great game but very niche with bit of a learning curve.
You’re even dumber I thought. Those sites mention (multiple times even) game account selling services (breaking TOS’s all around), gambling and virtual phone numbers (used in scams almost exclusively). You really think you’re going to get people using those sites?
