KeeperRL Alpha 28 is out! This update focuses on modding support, and also features new content and many quality-of-life improvements. At this point most of KeeperRL's content has been exported to data files and can be modded. Mods can be shared at keeperrl.com and downloaded directly from the game! A few veteran players have already published a mod with massive amounts of new content. I'd like to thank everyone involved in crash testing this patch, sending bug reports and suggestions. Your help was invaluable! Scroll down for a detailed change log.
If you would like to continue your saved game from Alpha 27, you can opt-in into the "Alpha 27 save compatibility" BETA branch under the game's properties in Library. Make sure to opt-out of the branch to go back to Alpha 28 when you're done!
