It's my pleasure to announce that KeeperRL Alpha23 is ready. It took four months to finish and because it consists almost entirely of gameplay changes, it's a very, very juicy release! The new features can be divided into three major groups. The first one redefines progression in the game, making it more dependent on conquest. Mana is no longer generated in the library, but is instead awarded for conquering enemies. A lot of construction and item prices were rebalanced to accommodate this change. You can optionally turn on mana generation in the library in the 'free play' mode, for those who will miss the old system. You can read more about these changes here. The second set of changes involves combat and training. Combat has been made more deterministic and slower, and creature attributes were changed to empower spellcasting characters. There are also health-bars! A major addition to combat is the 'full control' mode, in which you control every minion in the team. This redefines the combat experience in KeeperRL in a major way, making it much more tactical and fun. The last big addition is the 'endless mode', where you are tasked with defending your dungeon from incoming enemy waves for as long as possible. This is a game mode for players who don't necessarily enjoy venturing out and exploring the world. Conquest is optional. The highscores for this mode will be based on how many turns you were able to survive. If you would like to continue your saved game from Alpha22, you can opt-in into the "Alpha22 save compatibility" BETA branch under the game's properties in Library. Make sure to opt-out of the branch to go back to Alpha23 when you're done! The full change log: Gameplay
