I noticed that shooting speed bonuses apply to enemies. Is this intentional?

And damage bonuses are as well.

Thanks for the report, and sorry for the slow reply.

I went through the code and the mod only ever applies its bonuses to your own force. It never touches the enemy force, and damage and shooting speed bonuses are per force in Factorio, so I cannot see a path for a biter to pick one up. That makes me think something else is producing the effect, and I would rather find out what than guess.

Could you please tell me:

1. Which skills do you have points in, Glass Cannon in particular? It gives +10% weapon damage per point but also +6% damage taken per point, so a few points in makes enemies noticeably harder without anything changing on their side. Thorns can add to that impression.
2. Was this off a screen somewhere, or from how combat felt? If it was a screen, which one, and what did it say?
3. Are the enemies vanilla biters, or from another mod?
4. What other mods are you running?

Something that would really help debug this would be if you could (first copy your save, then load the copy, so you don't lose achievements), and run this in the console:
/c game.print(game.forces.enemy.get_gun_speed_modifier("bullet") .. " / " .. game.forces.enemy.get_ammo_damage_modifier("bullet"))
Both numbers should be 0.

Note the console line only reads the vanilla enemy force. If they run an enemy mod that creates its own force, it will read 0 while still leaving the question open, so answer 3 matters. One thing that comes to mind might be humanoid copies of the player character, but without knowing exactly what kind of enemies this happens to, I can only speculate.

It's possible that the mod is applying the effects to vanilla biters, spitters, and worms "on my force."
The way I know this is because on the bonuses screen it shows the above is affected.

I'm playing the Space Exploration suite with some additional mods. If you don 't think the above is it, I'll send you a list of my mods.

Yes, you are correct, the mod does apply the effects to all damage types on your force, including "melee" and "biological", which includes biters, spitters and worms. This is why it shows up there. This doesn't actually apply to enemies, though, only to biters, spitters and worms that are on your side (in your force).

If you don't have any mod that adds "melee" or "biological" allies, this is purely cosmetic in the bonuses screen. I could remove it, though, since the damage boost already affects your force, that would be a bit inconsistent or prevent correct bonuses from applying, such as you hitting enemies with melee (yes, there is melee in the game :)) ).

Ok. Then that makes sense. Sorry for the false report.
