Good puzzles and new mechanics (not as mind blowing as in Reloaded).
The plot is mediocre, kinda get tired of such type of jokes. Also few things are questionable considering the lore. There's a lot of segments between puzzles where you just walk and explore the same locations like you did in og Portal 2 or another mods (enjoyed "surface" tho) and walking speed is painfully slow. But if you hug walls it will be twice better.
Ending was rushed and ended on half-cliffhanger.
Voice acting is another story, sometimes I wished there was a mute button. Core that doesn't sound like core is cringe.

2hu Doom WAD you can finish in 30-40 minutes.
Levels are vast, but design is mid - visually appealing tho.
It has 4 boss fights, but they are over before you realised it - for some reason you need to empty only 66-75% of boss' HP. Anyway they have only 2-3 dammaku attacks (Patchuli has only one!)
Music bangs but loop is short but you won't be annoyed since levels are pretty short too
Nice weapons variety and the idea that on higher levels you are more OP (on lunatic no one have a chance against you)
I recommend checking workshop for even better experience

This game is more gameplay oriented unlike previous titles.
We have pretty small bunker with 5 locations to go and explore in resource-limited environment with ferocious beast following us.

The game was pretty scary until the moment I've met the monster - then it transformed into funny game of cat and mouse ¯\(ツ)/¯
Beast's behaviour pattern is pretty easy to figure out and read, even tho I died 10 times during that, and another 50 times after (I played on hard and there are enough of dead ends).

Puzzles in Bunker are pretty primitive, but game is honest and actually allows you to solve them multiple ways. Easy solution is more risky tho. And you actually use all the items you have at hand.

I wish Bunker's layout actualy was random, so replayability will skyrocket, because it's THAT subgenre of horror games. But instead only resource items location and passwords are randomized (and entire puzzle!!!).

Story is okay. No crazy plot twists this time tho. Was happy to see one reference near the end. That's all

Plot and cutscenes are 9/10. References to Xenogears are neat.
Gameplay is mid and boring, and slow (God bless turbo button). Even tho I somehow enjoyed stats synchronization mechanic, but I think it's not a feature, but an overlooked game design flaw - won't complain, being OP is funny.
Also didn't like (too) easy to miss stuff - forgot to return to the room you left right now - you will miss entire sidequest with generous reward.
Also game has really obscure secrets where you need to be in particular place controlling particular character (them being in your party isn't enough).
My "favorite" one is playground in the beginning of the dungeon, you need to travel for about 20 minutes, just to get a card for a hidden minigame.
It feels like they made it for replayability, but again in the end of the game there is a big middle finger for those who will decide to save clear data on the same save slot. Because you can't load clear data - it's for sequel to get few bonuses (swimsuits and something else). There's no NG+, there's no way to start from checkpoint before final boss, you just wasted all your progress. You also lose access to all minigames - therefore gameplay is 3/10
I don't remember any music during gameplay but in cutscenes it was good - 7/10
