Better to restart the whole mission altogether. Likely you won't get any trouble the next time.
Pogroms are meant to be very hard, especially to inexperienced crews.
A little technical help: due to a recent melee engine bug, enemies are immune to melee at certain angles (alwyas try attacking their back or sides. Or front but this is rarely a good idea
Never diagonally).
Tips & spoilers: to kill an armored enemy, you need to deliver enough damage to punch through armor. I can spoil a lot, but you know what a Personal Armor can take, plan accordingly, read equipment descriptions, think - there is a HUGE variety of equipment available
A little tip: they're killable with 1-4 strikes of a knife from the back & notice their laser guns can be picked up and used right away
I'm really sorry for these bugs (even if I'm innocent), but with the difficulty - yes, the mod is designed to kill you, and the enemies are designed to fight for their lives
Easy missions do happen. Sometimes. But not Pogroms. And there is no shame in grabbing some weapons & corpses for study & retreating.
Oh, Bows. Damage = 25. That's not a lot, not against the kinds of enemies you normally meet in Pogroms. They flying guys in gas masks can be killed with a bow, but with difficulty. Reapers too, if you have a lot of bows. The rest of the described lot, no, not really.
