My early game weapon triumvirate:
Flintlock Rifle - it's basically a sniper rifle made from scrap. The only drawback is 2 ammo per reload and runt-hours manufacturing it. It should't be as accurate, come on, it doesn't even have a scope.
Blunderbuss - the best shotgun. 4 ammo, can full auto, has chem ammo(basic is not bad either). The only drawback is weight.
Hunting bow with flame arrows - a very strong weapon IMO. Maybe not so good on the highest diffuculty because of increased armor(i play on 3rd). Low energy, can reaction fire, can set enemies on fire.
The camping strategy is very strong, i agree. Using shadowbat and these three weapons you can easily beat a nazi\spartan\raider pogrom. I had a bunch of various rifles and machine guns from these, but they feel inferior to these basic weapons.
Come to think of it, i feel like the game doesn't represent an advantage of having an auto weapon.(unless it's a shotgun) Even in the second year my best gals are armed with dragoon rifles, a bolt-action rifle(if i'm correct) that has a good aimed shot, buyable ammo, and scales up to 60 damage. It's not a problem of the mod, rather of a game engine. I also play a global mod for xenonauts(x-div) and in that game rifles and MGs while being inferior at actually dealing damage(compared to sniper rifles and shotguns at their effective range) they have their own niche, that is suppression. Idk if it's possible to realise it on this engine. Maybe if 2x2 enemies were the norm(but not the dangerous ones) and if every faction had some on their ships\missions then there would be a reason to prefer auto guns.
On melee weapons: i agree. However running a full melee gal is too risky imo until you get the chainmail. Amazon with a sword\blowgun is an insane killing machine, but it's a glass cannon. You make a mistake - you lose a gal. I feel like the big two-haders need something to differentiate them and reward you. It's a big weight\inventory investment that you can't just plop on a belt like a handle; that needs support items like booze. Also barbaric ax, barbaric sword and a regular ax could use more differentiation. Due to their scaling, 99% of the time they are 1 hit - 1 kill weapons. Barbaric ax is probably the worst one, it's basically an ax with a bit more damage for the double energy cost. Other oneshot weapons like hammer and anchor have their utility to differentiate them.
Barbarian armor is garbage, you can't afford such penalties so early on when your gals are untrained. Agree that pirate is better.
