I just finished my second playthrough of Prodeus. I still really like it but wish we'd get the rest of the campaigns. The game in it's current state ends on a cliff hanger. There was talk about 2 years ago about possible DLC but radio silence since.
I picked up Dusk, Cultic, and Sprawl from the Steam sale and played a bit of each. I did grab Amid Evil and Selaco but refunded those since they weren't really jiving with me. I'm waiting on a refund of Incision too since I tried playing on easiest difficulty and still had my ass handed to me. The game is super imbalanced.
Dusk, everyone probably already knows. It's has super fast strafey quake/doom movement. gunplay is decent too. The levels feel very Quake-like from what little of Quake I've played.
I'm not sure about Cultic quite yet but what I do like so far is the art style. It's fantastic. Think of those 16 bit pixel art gifs you see on like reddit that manages to create depth with very little colors but make that a 3D game instead. I was actually blown away a bit by the intro cutscene. It's really cool. The game is mostly just boomer shooter like you'd expect. I think it feels a bit like Forgive Me Father 2 from what I recalled. Others have said it's like Blood but I haven't played that.
Sprawl is scratching a bit of my itch from Turbo Overkill. It's more of a movement shooter but with old school graphics, rather than a straight up boomer shooter. It has a wall running mechanic and a slow mo mechanic which makes for some very stylized combat.
