only played the demo, which has a lot of features locked away or elements stuck in as a placeholder so it's not exactly even a full complete demo either. incredibly promising, combat is punchy as fuck, feels very much like a Build engine game (even though its running on GZDoom). world building and level detail is immaculate, theres a really painstaking amount of time put into little things like birthday cakes around a birthday party that act like health pick ups, and all the ways you can interact with the environment like petting roombas or using a fire extinguisher to blow up an MRI machine. most things in the environment react to gunfire and the combat scenarios are all dealt around incredibly tight corridors with lots of space to move around between rooms and get the drop on enemies, and its all so fucking satisfying.
game also has a 10/10 shotgun, just totally fucking explosive and brutal. theres a really good balance for most of the demo regarding not giving you enough ammo or health to really coast by most combat situations carelessly (bar for later on when the game hands over a shitton of assault rifle ammo to you, probably in preparation for the boss). there's a satisfying degree of challenge to this.
overall, the potential here is staggering. i think if the level design is tuned up a bit more and theres more space to move (and if they move away from the system shock 2-esque and doom 3-esque vibe of the demo levels) this could turn out to be a stellar boomer shooter. am very curious about all the additional replayability features too, like the randomizer mode and the mutators, and mod support. they also need to work on the optimization a bit more, i did run into a lot of stutters (usually whenever i saved) and frame drops were pretty frequent during encounters, but it was never too much of a distraction.
