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!

1 comment by Ionising on Jul 11th, 2014

Pardon the terrible pun in the title.. I was up until 2am getting everything together for today, however as the title may have hinted at already there is big news - Isomer is now available on Steam!!!

new build ( is available today in both Steam and non-Steam flavors. 

The versions are identical, however the non-Steam version will not have the additional Steam features like Achievements (and others in the future).

The focus of this build (aside from integrating Steam) has been improving combat and the AI of friendly units when under fire or in a group. Now, when a group of units is assigned a combat order, any units that don't have a line of fire will try to step into firing positions rather than just standing there as they did in previous builds.

Additionally, when a friendly unit comes under fire it will now raise an alert which will cause friendly units nearby to come to their aid automatically (if they don't have any existing orders).

Also new in this build is the information overlay (triggered by holding the shift key) which gives information about things in the world (i.e. entities, blocks or objects).

Aside from this there have been the usual collection of tweaks, bugfixes and general incremental improvements. The full changelog is below...

  • New: Added Steam achievements (to Steam build).
  • New: Added new game icon.
  • New: Added Steam mode to launcher (in Steam build).
  • New: Added polished enemy and friendly spawn point sprites.
  • New: Added polished menu images.
  • New: Added mouse context info screen triggered by shift button.
  • New: Added quit without saving button to in game menu.
  • New: Destroyed cacti can now be collected for biomass resources.
  • New: Added colours to entity notifications to make it easier to distinguish positive and negative events.
  • New: Added side step and target position finding for player controlled entities. Entities will attempt to step into a position from which they can attack a specified target and move back to their original positions afterwards.
  • New: Player controlled units will now raise an alarm when under attack causing nearby units to try to identify and also return fire.
  • Improved: Made some core stats (health, accuracy and defense) increase by set amount rather than percentage amount per level.
  • Improved: Updated title screen icons to use new colour scheme.
  • Improved: Updated game banner in launcher.
  • Improved: Tweaked heading colours in about screen to match new title image.
  • Improved: Removed greenlight banner in launcher.
  • Improved: Removed debugging code which should not have been left in relating to explosion diagnostics.
  • Improved: Improved code for game menu positioning and logic.
  • Improved: Improved unit selection (selecting unit from group now requires one click not two).
  • Improved: Half height human crates and cacti no longer block vision.
  • Improved: Improved weapon reloading.
  • Improved: Improved / sped up decision making cycles for entities.
  • Improved: Added new prefabs and improved existing ones.
  • Improved: If the player mines a block with an alarm sensor pad it will triger the base alarm.
  • Bugfix: Fixed bug where enemy Heavies and Engineers would not start with full health if they were not level 1.
  • Bugfix: Fixed bug with PowerCore integrity function returning 100% after power core was destroyed.
  • Bugfix: Fixed bug where particle engine would tick even when the game was paused.

To get the latest build update (for non Steam builds) use the Isomer launcher as usual, Steam will automatically update to the latest version. ;)

Regarding timing, it is very good now, I've got my copy in less than 2 minutes. And comparing to other games alpha versions Isomer seems pretty stable. Keep up your good work, it looks really promising. I'm happy with my decision to support you.

Game looks fantastic and I love the topics of your blog posts. They're extremely informative and excellent to read especially for other indie developers such as myself.

I bought it myself and can't wait to play, somewhat sad although that I have to wait 3-7 days to receive and play this awesome game. Keep up the awesome work and excellent blog posts!

Thanks Boxpipe, although you should be able to play it straight away after buying it via the humblestore widget? If you're having trouble send me an email to and I'll see what I can do!

It's all rather strange, humblestore is telling me it will take 3-7 days while paypal is telling me it will take 6-8 days to actually process the transaction?

I guess I'll have to wait the 3 more days see what happens. Hopefully nothing screws up and it's just taking a painfully long time for whatever reason. Still can't wait to try out your game.

Oh that's really odd.. I'm guessing it's something to do with your paypal account although that's the first time I've heard of such delays! If it's still causing you problems in a couple of days then send me an email and I'll forward it to the Humblestore people

As well as 45,324 ideas I need to share. We got a lot of work

here. As stated below the game is available to buy alpha now.
I'm having a lot of fun here, love the onslaught and the
constantly changing stock market feel of the supply ships ;)

:D I'd like to actually, I have my reservations about how the Greenlight system works (I had a chat with one of the guys over at Steam about their early access program too) - but it would be amazing to be able to get onto Steam.

My focus up until now was just to complete enough of the game to reach alpha. To be honest it's actually way more complete than it would need to be for an 'early' alpha build but I really wanted the first release to be good enough rather than release something that wasn't ready. Now that we're here my focus is now in planning and releasing updates and enhancements so if anything this would be an ideal time to think about Greenlight.
