- Beta 0.5.0: Character selection, stranger bosses, and more build variety - 10 September 2026
Build 0.5.0 is ready in the playtesting branch with new ways to shape your character and more trouble waiting in the depths.Crowded depthsI've added three additional bosses to the dungeon roster, which you will find randomly through the run. Boss rooms also appear more often from depth 3 onward.Hunters eventually begin stalking every biome, so going deeper should now feel a little less predictable and considerably less safe.There's also new enemies hidden in the walls, so be careful where you go near by.Choose your callingCharacter selection is now in, alongside new grafts and mutations: Lycanthropy, Debauchery, Reverse Engineering, Efficient Retrofit, Mnemonic Parasite, ... and much more.Survive out of scrapsI've added new recipes to craft different survival items out from disassembling junk or other items you may no longer need. Craft rudimentary ammo, chemical batteries, and acid amp…
- Beta 0.4.7: Electric synergies, new mutations, and clearer combat - 21 August 2026
Two builds landed since the last update, bringing new gear and dungeon mechanics alongside a fairly chunky round of interface polish.Shock, chemicals, and sabotageFive new electric and chemical weapons are now in, together with electric synergies. Automated turrets can also be sabotaged if you have the skills.The dungeon keeps getting strangerDigestive World and Abyssal Darkness can now reshape biomes, while Scar Tissue and Pathogenic Organic Mines adds new mutation options. There is also a new Nullification Therapy Injector for when your current condition needs a drastic change.Enemies are easier to readEnemies now display icons for their intended actions, and hovering over statuses shows a tooltip with more details. Stairs, inspection controls, tutorials, and safe-zone NPCs have also received clearer contextual information.Small things that add upAnti-venom now provides temporary pois…
- Beta 0.4.5: Bug fixes, QoL improvements, achievements, and cloud saves - 13 August 2026
Demo was released 2 weeks ago, so it is time for a patch to include general improvements as well as some demo-specific items. A lot of this came straight from your bug reports and feedback, so keep them coming!Feedback is always welcome, if you want to poke around early builds come and join Discord: https://discord.gg/VKSgsWA4GWImprovements around inspection and item interactionI got some bug reports/feedback from you folksFixed: Attempt to pick it up but inventory is full, make room in inventory, then pressing space on the same tile just says "There is nothing here."Fixed: I can pick up items from anywhere on the screen by right-clicking on them, and don't actually have to be on or near the tile.Fixed: There is not a keyboard key to inspect tiles / bring up a context menu like I can do with the mouse right-click, that would be very useful. Now the F key does that, of course is re-binda…
- Beta 0.4.4: New NPCS, ranged weapons that use your blood as ammo, and more - 7 August 2026
Thanks everybody for playing the demo! This has been live only one week, but hundreds of you already played. Very much appreciated.Initial feedback and bug reports are being worked on, for now I only pushed a new patch to the demo that was deadlocking folks with their default language in Spanish or Japanese, so I considered this one critical:Beta 0.4.2 - Fix: Starting the game in Spanish or Japanese by default sometimes wouldn't boot it fully.The rest of changes are currently sitting in dev-experimental branch for testing, and will stay there for a week or two before moving them to the demo and full game builds. If you want to give it a go, come and join discord for playtesting access! ScoreboardsYou're putting my runs to shame, I'm nowhere to be seen in the first 10 spots and beating my score just took a few days 😂The scoreboard in game is still a bit finicky, as Steam takes quite a w…
- Ad Iterum demo is out now! - 31 July 2026
After eight months of development, Demo is OUT now! Collapsing floors, gas vents, toxic traps, alarms that call the whole floor down on you, and corpses that were rigged to explode. Fire spreads. Oil ignites. Deep water hides things... the dungeon wants you dead. Enemies roll their own modifiers: Berserk, Poisonous, Elite, Infested, Oversized, Immortal... the same creature is never quite the same fight twice. Some explode when they die, others keep spawning foes until you deal with the source, while others will try to steal your gear and run away.Eat your enemies or find mutagens that reshape your body and the run: Phase through defenses, grow claws or quills, photosynthesize instead of eating, sprout a third eye... some are gifts, some are curses, most are both.You can also craft, and cook (you should probably cook, raw meat is always risky).What's in the Demo?1 dungeon with 1 procedur…
- Beta 0.3.6 v2 content pass: Luck, new bosses, new enemies, and new items - 16 July 2026
Beta 0.3.6 brought a starting point for endgame, multiple mutations, cloud saves, and endings unlocked, now the full patch is deployed in dev-experimental:Luck is a real stat now:Luck used to be a background number, but not anymore. Not only sharpens your dodge and critical chances in combat, but affects multiple game system as well.New bosses, and enemies:Eight new enemies and two new bosses have moved in, so the deeper floors bite harder than they used to. The quarantine depths have gained some new trap mechanics.New itemsImmunosuppressants, lucky eggs, and other new and unique items can be found. These could alter the run significantly.QoL improvementsSmall fixes and improvements here and there, like in-game bug reporting (no browser pop-ups), mouse clicks work again in Terminals and Vaults, and general stabilization overall.Public beta testing is permanently closed now, as we approa…
- Milestone reached! Demo coming up at the end of the month. - 7 July 2026
Milestone reached: DemoThe demo content is locked, and will come out at the end of July (it was initially planned for this week, but life got in the way and that won't be possible), so I scheduled for the end of the month.I also made a new trailer to announce the milestone!Last public play testIf you've been meaning to try Ad Iterum while it is still changing fast, now is a good time. I'm mostly looking for rough edges: unclear UI, weird balance spikes, confusing systems, crashes, broken builds, all the usual things that only show up once you folks play:Why last? After the demo is out, all play testing will be done exclusively in private through discord, as will make no sense to have both demo and play test out through steam. While the demo is locked out to the first dungeon/biome only, the play test generally contains the full scope of the game, or very specific builds when something n…
- Beta 0.3.6 - Endgame: Multiple mutations, cloud saves, and endings unlocked. - 26 June 2026
While the beta 3 play test was running, I kept working on the next milestone. Public demo is getting closer, so keep an eye open.Endings unlockedThe game had no ending! ... till now. Two of the game's endings are now actually reachable, if you've been wondering what's at the end of the run, now's a good time to push for it in the dev-experimental branch. Your decisions matter.Progress that sticksSaves now carry across versions. No more losing settings and progress every time I push a new build. This was intentional, not only because of the permadeath system and roguelike nature of the game, but so I had plenty of room to experiment without having to deal with early messy data migrations. There's also a "reset data" option in settings if you ever want a clean slate on purpose.Stuff to swing, eat, and avoidBig gear pass: four new weapons, armor pieces, and random items like spider eggs an…

- Preparing for Beta 3: New biomes, superior weapons, and double the content. - 5 June 2026
The world keeps growingTwo more biomes have opened up, on top of the acid pools added a couple of weeks ago. The deeper you push, the stranger things get. Sharper weapons, nastier companySuperior weapons are now a thing you can find out there, and you will need to defeat the new enemies that joined the roster in the Quarantined Depths.There are places you haven't seen yetYou may find secret rooms scattered around, these are not necessary for progress, but may contain nice treasure... or a nasty surprise.Careful who you trustBlood pacts are more extreme now, if you choose to accept them.Small things that add upStatus effects got proper icons, new memories show a "!" indicator until you read them, world NPCs do the same, multi-turn heavy weapon kills no longer leave a stuck waiting icon, cooking in environmental fire works again, traps grey out when disabled, blood pact UI fits 3 pacts pr…
- Ad Iterum Beta 2 on GameEffect Showcase 2026 - 28 May 2026
Beta 2 has been up for playtesting for a couple of weeks now and I've started to address the feedback, heading to Beta 3.The game also has been featured in GameEffect Showcase 2026!Quarantined Depths, and new Blood PactsA new boss is waiting for you, along with new creatures lurking in the Quarantined Depths. And if you're the type to make deals you'll regret, there are new Blood Pacts on offer too. Power always has a price.Gear with teethA whole wave of affixes landed: Parasitic, Thorns, Ward, Brutal, Reflective, Glass, Reinforced, and more. Every one is a trade-off: heal on kill but bleed out over time, hit like a truck but shred your weapon, see further but get spotted easier. Broken gear is now properly inert, so you'll feel it when your favourite blade gives out.Cooking actually cooks nowA couple of things around food were broken. Eating corpses straight off the floor now properly…

- 0.1.11: Tier 1 Dungeons are here, and do not play nice. - 7 May 2026
Big week! I've added the Tier 1 dungeons with 3 new biomes. These are entirely different than the beginning of the game, or what I'd call Tier 0. New challenges, new gear, and more progress that unlocks the first half of the game towards 1.0 release.New dungeons are accessibleNew biome-specific terrain hazards, tougher enemies, and environmental dangers around every corner. Old and unstable tech that has new ways to punish you... the good news is the loot matches the danger, so you're not fighting acid-spitting horrors with a crude pipe wrench anymore :DNew gearYou're going to need better equipment to keep up as well, with two new armor affixes available: Insulated and Sealed, that should help you survive the new depths.Visually, equipment finally looks like actual equipment, armor and weapons now render their specific piece on your character instead of generic sprite blobs. It took me…
- 0.1.6: Heavy slams, tooltips, and new strangers - 30 April 2026
First chunky update since Beta 1! Here's what's new:Heavy weapons finally feel heavyThis was bothering me for a while. Swinging a massive two-hander and having it just... tap a single tile felt wrong. Heavy weapons now attack in area and slam patterns. Wide swings, ground pounds, the kind of thing that should make you feel powerful and also a little reckless. There's someone new thereSome new strangers, and unsavoury characters have shown up. They might be worth talking to.The UI got a lot of attentionA few things that have been quietly frustrating got fixed in this update:The Status screen was redesigned, is not quite there yet but now it actually tells you clearly what's affecting you. Tooltips landed across the board adding some additional context to the items or enemies you find through the world.Small things that add upCured meat stacks as a single type instead of clogging up your…
- Beta 1 recap. Your deaths were not in vain - 23 April 2026
Hi everyone! The first beta of Ad Iterum wrapped up last week, and I wanted to share what came out of it.20 players jumped in. You explored over 1700 tiles per run on average, fought through nearly 19 enemies per session, and 95% of you hit retry immediately after dying. You kept going even when the dungeon keeps killing you.Half of you died unarmed.Floor 1 is the deadliest floor.Spawnlings are the #1 killer, accounting for almost a quarter of all deaths.You were fighting hard, averaging 19 kills per run.14% reached a boss encounter.21% found a safe room.76% of deaths happened with no armor equippedWhat's changing? Weapons on floor 1 will appear more often while you're unarmed. No more starting a run empty-handed. Enemy density and strength on floor 1 are being reduced so you have room to learn the systems before the dungeon tries to kill you. Spawnling rebalancingMore armor on early fl…
