(Had to launch it from Steam to play due to controller issues, hence the short playtime GOG has.)
I really, really disliked this game. It's not...the worst thing I've ever seen, but at its best it's VERY mediocre and forgettable. The rest grades down from annoying to aggravating to un-fun.
Complaints in no particular order:
-Level design is extremely repetitive. Every room looks exactly the same within a "biome" and all of them are similarly designed.
-Clunky controls.
-Boring combat. Very limited number of enemy types/setups. Guns are nominally different but all play the same.
-Terrible, terrible hidden secrets you can only find with a guide.
-Unlikable, annoying characters with terribly written dialogue.
-Almost no bosses or interesting encounters.
-The story and pacing are bad, at least through 40% or so of the game, when I got disgusted enough to stop playing.
-The jokes in the game are really, really bad. Not offensive, just...anti-funny. And not in a bathos humor way. Just incredibly mediocre and bad.
-Waiting for enemies to respawn is tedious and boring.
-The skill tree progression is pretty arbitrary, although I guess some of the ideas are OK.
Good things:
-Representation in the cast, sort of. One of the two support NPCs is a black dude and the protagonist is female.
-The ghost/possession mechanic is interesting but it's used to do something fun exactly once. The rest of the time it is a slow and obnoxious chore.
TL;DR: not worth. Awful writing, VA, and level/enemy design. The gameplay is slow and mediocre and is still the best thing about the game.
