RimWorld Alpha 18 unstable version is now available on the 'unstable' branch in Steam. Current build is 0.18.1700.
This version is unstable. There will be bugs, imbalances, and other annoyances. It won't be as good as the final build. Your game may get ruined by something really dumb. The game will update with no warning and anything can break or change. Please only test if you're willing to put up with that!
To use the build: In Steam, click RimWorld -> Properties - > Betas tab -> select 'unstable' branch. Restart Steam if necessary.
To report feedback: I love to hear play stories, balance feedback, and so on. Please feel free to post feedback in this thread, or make another thread. I can't reply to everything but I do read everything and take notes. The most useful feedback reports what happened in the game, and is based on longer experiences. Suggestions are cool, but stories and bug reports are really the best!
Please only post feedback specific to things that are new in A18; long-standing issues, suggestions and discussions should not be posted here please.
To report bugs: A bug is when the game isn't working as designed. If you find a bug, please report it in the
Bugs forum, following the instructions in the
How To Report A Bug thread. Much appreciated - public bug reports are essential!
Compatibility: Saved games from
vanilla Alpha 17 should still be loadable, though some things may change. It'd be great if players could report any bugs with loading A17 maps. Complex mods won't be usable. Very simple mods may still load.
Announcement: I'm not trying to spread the news wide because the game is still unstable; I'd rather get some dedicated test time from the dedicated players here first! So of course it's fine to talk about it, but I won't be spamming all the PR channels with this. I will be spamming them when the alpha is actually done.
Video makers: I won't stop anyone from making videos of Alpha 18 in its unstable form, though I'd prefer you didn't. The experience may not be up to the standards of the public builds, because it hasn't had that level of testing, and I don't want people getting the wrong impression.

Rough features list:

-Storyful combat:
----A major rework of melee combat, and a new way to report all combat interactions. Storyful combat generates a combat log that reports each blow, miss, swipe, block and fall in the combat. During or after a fight, you can review the combat log to see what happened, to generate a richer story.

----Bedroom tantrum. Go to your own room and randomly smash furniture, buildings, and damageable items.
----Targeted tantrum. Go to destroy a single, specific, randomly-chosen, valuable item or building.
----Sadistic rage. Melee attack prisoners for a while. Fists only. Only occurs when there are prisoners to attack. Does not attack downed prisoners.
----Corpse obsession. Dig up a corpse and drop it on a meeting spot table or in a random high-traffic area. The mental break then ends.
----Catatonic. Collapse on the spot into a downed state with a psychological breakdown. Recover some days later. This can be implemented by a “catatonic breakdown” hediff.
----Jailbreaker. Colonist goes to a random prisoner (who is capable of prison breaking), and upon doing a special “spark jailbreak” action with them, induces an immediate prison break in that prisoner.
----Slaughterer. Slaughter random colony animal(s) periodically.
----Murderous rage. Hunt down a specific colonist or prisoner (randomly chosen) and attempt to kill them by melee attack. Uses melee weapon or fists, as equipped. Keep attacking until the target is dead.
----Run wild. The pawn basically starts acting like an animal. You can tame him to try to get him to rejoin.
-New mental inspirations. Basically reverse mental breaks - these give temporary bonuses to colonists in high moods.
----Work frenzy (1 day): Global work speed 2.5x
----Go frenzy (1 day): Walk speed 1.5x
----Shoot frenzy (3 days): Shooting hit chance improved as though the pawn is 10 skill levels higher.

-World features like lakes, mountain ranges, and bays are now detected and named. Names are displayed in the world view.
-Caves now form sometimes in mountainous maps. Inside there are special cave plants. There can also be dormant insect hives.
-Many new tale types were added. So, the game will record many new types of events, and colonists can make art about them. Art descriptions should be much more diverse.
-Crop blights now appear and spread over time instead of instantly destroying crops
-Spaceship is now bigger and has one more component, the sensor cluster
-Spaceship quest ending phase: When going to the hidden space ship to finish the game, the game does not end instantly on arrival. The map generates with the ship intact. To take off, first you must power up the ship, which takes some days, during which you must survive raids.
-Space ship construction now requires advanced components, which have their own tech tree and production method
-Split pistol into revolver and autopistol
-Artillery works differently now. There is one type of mortar, which can fire any type of shell, with each shell creating a different effect. The shells are explosive, incendiary, firefoam, and antigrain (a special high-tech warhead).
-Seasonal latitudes: Seasons now more reasonably adjust depending on latitude. Instead of flipping at the equator, there is a seasonless crossover zone.
-Redesigned alert letter types and sounds to be more specific.
-Pawns can now be banished. This is analogous to abandoning pawns in caravans.
-Many many tunings, bugfixes, and redesigns.
