you can tell the dev was mad that people didnt like his dumb story in the first one, and only wanted more gameplay. this games whole shtick is "more superhot". unfortunately what "more" means is around a half dozen levels that you kill infinitely spawning enemies in and then repeat the exact same levels in a different order and spawning somewhere else a million times.
hacks are cool, and i like the idea behind cores but im not gonna choose a cool but ultimately pointless ability over more lives, are you insane? i didnt get far enough to meet the dreaded dogs ive heard so much about, but judging from what ive heard, all they do is make the game more annoying and not fun or really challenging.
new weapon types are really neat, sniper is a blast and i love knives/shuriken.
ultimately the vr game i played at a friends house was the best one, because it actually made me move around and there wasnt any story (from what i played). according to my friend i "got way too into it" which is code for "you did a somersault and punched my brother in the shin"
