Does your mod work on these mods?
Fulgoran enemies mod (https://mods.factorio.com/mod/Electric_flying_enemies)
Factorio+ mod (https://mods.factorio.com/mod/factorioplus?from=search)

Does your mod change health with the higher levels or is it just damage

Health is only changed with quality. Research upgrades affect damage, attack rate and cost to join attacks.

The only thing needed to manually adjust for mod support is new spawners and new surfaces, due to how pollution absorbtion is calculated per entity type on each surface. Everything else works automatically. Looking at those mods, Factorio+ should work just fine, it only adds new units, not spawners. Fulgoran Enemies I'll have to make an update for, but only pollution absorbtion factor is missing here, other parts of the mod will work.

Thank you for the quick response.

Sorry I have another question. It might be a dumb one but does your mod affect demolisher? and if so does that mean it works on Behemoth Enemies Mod (https://mods.factorio.com/mod/behemoth-enemies)?

Research upgrades affect damage by type. Any unit using "melee" and "biological" weapon category is affected. Behemoth pentapods are supported by default.

Demolishers are entirely unaffected.

Ok thank you
