Got a few things to say:
Some info-cards just suck.IFM mail doesn't have personnel list at all,and only some cards were truly interesting.
Bugs are too fast.
Bugs dont have attack animation except the ranged ones.Very annoying since they just drain hp and can be too near to player to shoot 'em.And I would like at least some kind of attack animation,not some hp drain that kills you in a few seconds.
Some weapons are just useless(SMG<Anything except pistol).
Would like some attachments for pistol and more/longer levels.
Bosses suck.(They're just big enemies,no name or some sort of attention to them at all.They're just big ranged bugs.)
Wish game had more dialogues and info-cards.
The door hack swarm attack sequence sucks.It's not even dangerous that much with a bit of strategy,they're just nice 'cus of the music(reminds me of AvP alien attack sequence during the door hack,nice inspiration you got there).
How to win:
2.Buy FMJ attachment for shotgun.
3.Buy Dual Mag attachment.
4.Kill everything with you DOOM-class shotgun.(Doomslayer would be proud.Doomslayer btw is just more experienced Doomguy.)
Bugs are not interesting.Small ones should be the swarming ones while big ones should be "leaders" of swarms and black big ones be more of a hunter and attack from the back.And ranged are fine.
Please,remake/remaster/reimagine this part.It's good,but got some flaws.
