KeeperRL - Michal Brzozowski
After releasing the last Alpha 29 fixes I've been very busy with adding new, shiny features to your favorite game! In order to keep you excited for KeeperRL Alpha 30, here is a quick rundown of what's coming.

Playable Gnomes faction

Almost all mods add new playable factions to the game, so it's obvious that this is something that players crave. At the same time I want to make sure that new factions offer significant new gameplay experience, and aren't just reskins of existing mechanics. The new Gnomes faction will do exactly this! Being expert craftsmen by nature, gnomes dominate by constructing automatons, advanced traps, and other machinery. Automatons are assembled from basic parts, and every configuration offers different capabilities. You can create your own custom builds! Another thing that's unique about this faction is that there is no unique Keeper creature. The success of you base will depend on keeping any of the gnomes alive.

Minion titles and kill lists

I've set out to make minions feel more personal, and less like expendable cannon fodder. The game will track their kills, and give them titles for killing tribe leaders, along with significant bonuses. The Keeper will also write poems about your minions' triumphs and failures.

Group activity disabling

One of the oldest feature request was to allow disabling chosen activities for larger groups of minions. This is now possible!

White Knight faction additions

Thanks to the generosity of Archdiggle, the author of the Dig Realm mod, who kindly agreed for some of their sprites to be used in vanilla, the White Knight faction receives new minions and structures. The main addition is a group of angelic minions.

Mod merging

I've implemented further improvements to the modding system, and now one or more mods can be merged together. This means two things:
  • Modders no longer need to copy the entire vanilla content to add their changes. Every mod consist of only what it changes or adds, even if it's a single line.
  • Multiple mods can be used at the same time!

Custom map layouts

Modders can now circumvent the built-in procedural town generator and use their pre-made map layouts. The towns 'skins' (wall, floor, furniture types, etc) and defined separately, which lets you easily generate a lot of different-looking towns.

New spells and traps

New types of effects will arrive in Alpha 30: a spell that animates weapons, a trap (or spell) that sets off other traps in its vicinity, an effect which covers you in oil (and makes you flammable), and others.

Multi-weapon combat

Creatures will be able to attack with multiple weapons and body parts in a single turn. This includes multi-wielding weapons if one possesses the appropriate skill and number of limbs, and using extra intrinsic attacks, like poisonous bites, kicks, etc. This feature makes certain creatures, like werewolves and vampires, much more interesting and powerful.

I'm not going to spoil you with details, but in the future KeeperRL will have an 'ultra' ending, which will requires finding secrets and beating special areas and bosses.. Alpha 30 will include some new, hidden levels that are part of this. I'm curious to see how quickly you can find them!

Making Zombies Great Again!
Last but not least, zombies will receive their long due power-up! They will possess a 'swarmer' trait, which makes them more powerful when more zombies are around. Therefore a large horde of zombies will be extremely dangerous!

This patch fixes a critical issue with downloading Steam Workshop items that caused the game to crash. Opening in-game links on Mac has also been fixed.

Using the opportunity I put some pumpkins in the game too.

An unofficial Alpha 29 build is out on the BETA branch. Check it out if you're an experienced player and want an early glimpse of all the new stuff!

Please post your feedback in this thread or in the comments below.

Please don't opt in if you are new to the game, as this build is very unstable, and the tutorial doesn't work at the moment.

To opt into the build, please go into the game's properties, BETA tab, and choose the "dev" branch.

Besides Steam Workshop support, Alpha 29 is going to bring a large amount of new content and mechanics for your enjoyment!

New biomes

KeeperRL will receive two new enemies with their own biomes and even dedicated soundtracks! They are: thieves in the desert, and a white dragon in an arctic setting. Both environments come with new mechanics and some juicy surprises! You can't build in different biomes yet, but it's something that will definitely happen at some point.


Totems are structures that place a certain buff or debuff on all friendly or hostile creatures in a given radius. The player has a healing totem available to build, and some locations feature other totems, like bleeding or blindness. They will mix up the combat mechanics in the game quite a bit. This is a feature that was suggested by player Amaze, if I'm not mistaken. Thanks!

Special item ingredients

Some (mostly major) enemies will drop body parts that can be used as ingredients to craft special items. This is in line with my efforts to give the player more rewards for exploration. Some of these crafted items will be very interesting :). The mechanic is fully moddable, of course.

Freezing mechanics

Along the new arctic biome and the white dragon enemy comes the effect of freezing, which interacts with water and other creatures. The reverse is also true - you can melt snowmen and igloos using fireballs :)


Originally intended for a new type of demon, this skill allows you to infiltrate the enemy lines. Great for gathering intel or stealing stuff! It's not clear to me yet whether it will be activated by a ring or by some other means, and I have to make sure it can't be used to evade attacking enemies forever as the Keeper.

Shields and the parry mechanic

Shields have been present in the game for a few updates, but they needed an overhaul. Thanks to some helpful input from players, I've added a new combat mechanic that makes them more relevant. If a creature is attacked multiple times within one turn, its defense stat gets a penalty for each attack. This makes it easier to take down very strong enemies if you have a large team of average creatures. Shields counteract this effect, for example an adamantine shield will let you take on four enemies at once before your defense is lowered.

Plague effect

Plague is a similar effect to poison, but it won't kill most creatures (and some are totally immune). It's also highly contagious. Have fun with it :).

Enemy aggression setting

You can now switch between three enemy aggression levels, with the lowest one completely turning off enemy attacks. The medium level will keep the normal aggression, and the extreme level will cause every active enemy to attack within a few thousand turns, provided that their population is high enough.

The last few KeeperRL patches improved modding support to the point where you can change or replace the majority of the game’s content. I’m very happy that a few hardcore fans jumped at the opportunity and published some really cool things, and the most popular mod is played nearly as much as the vanilla game!

The game features a very simple interface for downloading mods, but a far better framework made for mod sharing is the Steam Workshop, which supports commenting, ranking, subscribing, searching and all the other things necessary for a great sharing experience. And thus I brought the coding guru Krzysiek onboard again, to integrate it into KeeperRL. Once at it, we also plan to support sharing of retired maps through the Steam Workshop.

I hope to release a testing build integrated with Steam Workshop in late August/early September, so we can work with mod creators and players to make sure the experience of content exchange is as perfect as possible.

For players that don’t use Steam, all content will also be hosted on the server, as usual, but without the extra functionality that Steam Workshop supports. I feel bad about creating this inequality, but since more than 95% of players play on Steam, it would be a mistake not to make use of the extra free features that it provides.
