A small mod to unlock the Fishman race, which was hidden in the game files presumably until the last quarter of the map is finished. 
I'm not that active on Nexus. I might take a while to respond to comments. If I update the mod I will also update it here.

NOTE: I made small tweaks to the race to give them more interesting play (in my opinion). I'll list them here:
- Increased healing rate by .25, to reflect how I don't understand marine biology.
- Added very slow self-healing, because fish do that. 
- Lowered hit chance of left arm from 200 to 140, because it was over double all other limbs and results in a lost arm every battle from the new limbloss update.
- Raised left arm hit points by 15, to ease the fact that it's still more likely to be hit than any other bodypart.
- Took the +20% athletics bonus and made it -20%, because the fishmen already have faster base running speeds than humans, because fish feet are clearly better suited to the ground than water apparently.
- Blood is a slightly more purple colour but still red.
- Can now wear shirts, but hats and shoes are still disabled like default. Let me know if that's annoying. (Beware: Shirts can clip through the fishman model if you're too fat, so don't be)
- Slightly increased water avoidance to -1, as it was -3 before and that resulted in my fishboi going out of his way to trod in shallow water instead of running away from imminent death.
- Penalty to first aid, to account for the higher heal speed
- Penalty to lockpicking, because you have no thumbs
- Bonus to dodge (move like a fish)
- Bonus to dexterity (strike like a fish)
- Bonus to perception (see like a fish)


Let me know if you want anything changed. This mod will probably stop being necessary after the game is fully released and the fishmen hopefully get added into the base game.
