Q: Is this mod compatible with X?
A: Probably, this mod is only adding things, its not overwriting or editing existing items so it should work.
I can't guarantee anything though
Q: Should I use this instead of the original Armoured Biters?
A: Only if you're on Factorio 2.1 and the original hasn't been updated for it yet. Once CybranM updates the original for 2.1, switch back to that and drop this fork — check https://mods.factorio.com/mod/ArmouredBiters for updates.
Q: Can I run this alongside the original Armoured Biters?
A: No, and the mod manager won't let you try — this fork declares itself incompatible with the original on purpose, since they'd both try to add the same enemies.
