Biters now drop alien ore that can be smelted into alien plates from which you can craft alien items that have bonuses over their vanilla counterparts. The mods balance can be configured via global settings.
This mod is incompatible with Rampant at the moment (see https://github.com/renoth/factorio-alien-module/issues/22) it is possible to use the compatibility mod however: https://mods.factorio.com/mod/rampant-alienmodule-compat
