Isomer is an isometric realtime strategy game with world exploration and survival elements, where the player controls alien forces hell-bent on conquering human worlds for their resources.

The worlds are large, teeming with catacombs and life, procedurally generated with gameplay inspired by classic XCOM and dwarf fortress style games. Each play through is unique presenting different challenges and requiring different tactics.

Isomer is evolving constantly as we add more features and content.

Early access to Isomer is available on our website, current features and progress can be found on here and on the development status page!

After a few days of downtime following the crunch involved in getting Isomer ready for Steam, I have just released a new Isomer build. Build focuses on enhancing enemy bases in a number of ways and fixes bugs reported on the forums from the last build.

So, what's new with enemy facilities? Firstly there's a new block called an alarm control core - this block can be found in some enemy bases and controls all the alarm sensors throughout this facility. Destroying a base alarm control will disable all the sensors and alarms in the building making it easier to assault the powercore without interruption.

Secondly, enemy bases can now extend underground! Previously no enemy base could have any part of it below the ground, as of this build several buildings have extensive underground rooms and corridors adding to exploration and discovery.

Aside from this, two entirely new enemy buildings have been added and more than ten others have been tweaked and updated. Below is the complete changelog for this build:

  • New: Enemy units are now damaged by touching biomass plants.
  • New: Added new enemy buildings.
  • New: Enhanced enemy facility generation by allowing buildings to have an underground facilities.
  • New: Game version is shown on title screen.
  • New: Added new transition screen with stars rather than tiling scrolling background.
  • New: Enemy bases can now have their alarms disabled by destroying the alarm control block.
  • Improvement: Updated player dropship.
  • Improvement: Player spawn points can now be built and now require minipowercores.
  • Improvement: When a new game is generated the local world around the starting dropship area is automatically revealed.
  • Improvement: Steam achievement 'Cut the red wire' (related to disabling alarms) now can be achieved.
  • Improvement: Enhanced a large number of existing prefabs.
  • Bugfix: Fixed bug where enemy units would loot resources for the player!
  • Bugfix: Fixed bug in launcher which would enable the non-Steam update option if it failed to read the locally installed version number.
  • Bugfix: Fixed crashing bug with generating 2D selection block that goes off the edge of the screen.

As with previous new builds, you can update Isomer either via the Launcher (if using the non-Steam version) or by letting Steam handle the process for you automagically!

Well, there already exists a mod on the Steam Community Hub that allows you to do exactly that. Just look up "Play as the Humans Mod" in the search box. ;)

I whish I could try this. I actually purchased the game but it refuses to run. First there was a missing DLL file. I installed this and that particular problem went away. But after that the launcher krashes without exception. I've tried to install the the frameworkd mentioned on the forum. I've tried running it as admin. I've also tried kompatability modes of different kinds. But it krashes with the error: 0x000007b every single time. My system is a win7 64-bit system with a i7 920 CPU running at 3.1 Mhz. 12 GB memory and a nVidia 660 graphics card. No other games are giving me any problems so I can not for the life of me figure this out. If anyone know any solution please tell me!

Sorry about the double post. I should have gone to the support forum directly. But I was lazy since I was not registred there. I've seen your reply on the forum and made a reply. Let's continue the thread over there...

No plans at the moment I am afraid. Top priority for now is getting all the features and mechanics finished. Decisions about other platforms will come later :)

There's some spare development time for the next build while the sprites and audio come together so I'll see what I can do. I don't suppose you fancy doing a brief trailer for Isomer do you? :D

Whoa. Sorry I wasn't able to login to this site for quite a while now. I'm very active on my Imbacore YouTube channel though. I do Let's Plays and How To's and Guides.

Where did you send it? There's nothing on my ModDB inbox.

Once this goes out on Steam it's an instabuy for me if nothing dire comes up where finances are concerned. :D

Had I been animating vertically my pebble would probably have died during the light. Pretty cool to know #gamedev

RT @NemoNaemo: I wish there was a "pick random races for the AI, but no mirror matches plz" button in most 4x games.
