Alpha Genes Mod

Author of the Alpha Genes Mod: Sarg Bjornson

Alpha Genes Mod features

  • More than 200 new genes. Some are very low impact, while some are truly game changing.
  • 10 new xenotypes with wild mechanics.
  • A new “Custom random” xenotype that allows you to make new player created xenotypes, and have them loaded into two new custom factions.
  • Abandoned Biotech labs quests, similar to the ones in VE Genetics, that give access to all the new genes during play.
  • Genetic tools that allow you to tweak your colonists’ genes. Obtainable through lab quests or normal quest rewards.

A list of genes can be found on this Google Docs document.
