Lackluster Bestiary
Hello! I am currently reading through IM core rulebook preparing to run a test game and I can't beat the feeling that potential combat enemies presented in bestiary are focused mostly on imperial citizens with barely any options for game focused on xeno threats.
This game would be perfect for campaign focused around genestealer intrigue but there is just one tyranid stat block. I presume I am supposed to treat cultists stats as if they could be genestealers and ignore chaos elements of them? It's kinda strange.
What about orks, necrons or even examples of planetary fauna? There is nothing in this book, despite lore stating that all are valid threats in the sector for players. It all feels like there should be a bonus book with more enemies but there is none.
Does anyone have any clues that could help me expand the options or maybe homebrew materials for more enemies that aren't just imperial citizens?
Edit: Thank you all for answers so far, I am checking mentioned options. Additonaly - Which of the published books you would say has most additional statblocks for enemies, so that I can expand my base for homebrewing?
