KeeperRL Alpha 26 is out today. This is a big content update with new game mechanics, basic modding support, and if that's not enough, it also introduces dozens of new animations and special effects! This update allows you to construct buildings outside of the dungeon. You can choose to dwell in a castle if you're not a fan of caves. There is also a new Keeper character, the White Knight, with a new set of minions and enemies. He/she is similar to the Duke nemesis found in the campaign. If you would like to continue your saved game from Alpha 25, you can opt-in into the "Alpha 25 save compatibility" BETA branch under the game's properties in Library. Make sure to opt-out of the branch to go back to Alpha 26 when you're done!
