RimWorld: Positive Genes Tier List

I know what you’re thinking when reading that title, no it’s not Eugenics. Rimworld can be many things, organ harvesting, drug and booze empires and war crime simulators, there’s no space for more bad titles the game can give us, hopefully. Rimworld is a dangerous game just because of how much dubious stuff you can do in it, and now with the new DLC adding a bunch more into the game, it just gives us more options to incriminate ourselves. Today we’ll be looking at the positive genes you can get in the game as well as a tier list to see which is the best ones.

With the recent release of the Biotech DLC it added something that was only possible with mods before, and that is genes.

Now pawns can have a number of genes and you can even have ways to change those genes. Some of these genes range from simple ones like being optimistic, to game changing ones like being Deathless. In this article we’ll show you which are the best and worst ones!

• Coagulate – Ability to quickly close up wounds, this is obviously one of the best genes out there.
• Deathless – Your pawns can’t die unless their brains are destroyed, the best gene in the gaem!
• Elongated Fingers – Adds more manipulation to your pawn, the most important stat in the game.
