I'm playing 0.17 with space exploration mod, but I don't know anything about modding this game, so I can't give you suitable data. But I've build 1 cannon and have decoyed only 1 biter and the turret didn't survive that.
...maybe. But I have the impression that biters/spitters in space exploration are much more aggressive (??) and I need only weapons that kill them reliably. Nevertheless: Happy gaming !
I can add extra balance for specified mods, but nor for all of them.
Please write me the list of mods / attach the "empty" save game file for mod sync.
