Introducing Overgrowth!
Coming soon... Overgrowth Now available for preorder!

Wolfire Games develops innovative, independent games for Mac OS, Windows, and Linux. It was started by David Rosen in 2003 to organize his open source video game contest entries. After graduating college in 2008, he was joined by his twin brother and three friends and Wolfire Games officially dove into the independent game industry!


We have finished our first shareware game, Lugaru. Please check it out here! We are currently hard at work on the sequel, Overgrowth, and you can follow our progress on the Wolfire Blog.

Overgrowth Progress: Late June 2017

7 comments June 24th, 2017 by David Rosen

Project Status:

We have finished the major art pass on the new Overgrowth campaign. All new levels are in place, and the majority of work on level layout and environment art is complete. This means we have also scaled back the team again to the same size we had last November - just David, Max, Lukas, and Merlyn fully allocated to the project.

We've been spending the last month on improvements to gameplay and story, small effects improvements, more character animations, a tutorial system that's better integrated with the game, and tons of bug fixing.

Changelog for the last month:

(This list reflects changes to internal_testing - not all of this will be present in Beta 4. If you have the game on Steam and want to try out these changes early, open your Game Library -> right click Overgrowth -> Properties -> Betas tab -> switch from "NONE" to "internal_testing")

Gameplay changes:

  • Made depth of field (DOF) change when taking damage (world gets blurrier)
  • Made damage DOF and vignette fade over time so you can see distant characters more easily
  • Begun work for per-level loading screen images, and added placeholder screenshots for all of them
  • Begun work for per-level loading screen text
  • Begun work for hints upon death, and added several detected death types to hint about
  • Fixed nearsighted bug with NPCs

  • Added defeat/victory "sting music" support
  • Made it so hands are put up when grab key is held
  • Smoother landing when floor is marked as "ground" with physics painting (fixed some weird deflection/bouncing in some levels)
  • Made falling damage bypass KO shield
  • Made footsteps louder, so you have to be more careful when sneaking up on enemies
  • Made rabbits hear more clearly, and made it more obvious when they are listening

  • Made it so you can sneak attack an enemy if they're investigating
  • Added slight magnet towards enemy when attacking
  • Added NPC skill parameter for shoulder throw counters
  • Increased NPC throw counter probability, but made it scale on game difficulty
  • Made enemies rush you when you have a weapon and they aren't on a shoulder throw cooldown

  • Made low attacks w/ dog sword a slash instead of a thrust
  • Made enemies vary attack timing when you block or dodge
  • Did some experiments with a flying leg choke, but reverted script changes since it was taking a long time to implement

  • Fixed several crash bugs when various assets are missing or filename fields are incorrect in XML, etc

  • Minor improvements to mod documentation (Data/ExampleMods/mod_xml_specification.txt)

  • Made it so you can directly set water to be lethal, without having to make an additional kill hotspot

  • Added memory initialization to many places where memory was not initialized
  • Fixed some crashes when NULL vendor returned by GPU (slightly better handling of some under-spec cards)
  • Attempted fix at IMPulseAlpha error message (this error is basically a crash on top of a crash, so all that should change is that we now get better error messages that are more relevant)
  • Improvements to deployment so we miss fewer files
  • Fixes to asset conditioning pipeline so we have fewer build hangs
  • Added support for single-shot asserts (so players don't get repeatedly spammed when things go pear-shaped)

  • Updates to unique characters, and placed many of them in levels
  • Many tweaks to level 1 gameplay, checkpoints, and initial spawn positions to better teach stealth and platforming

  • Increased player KO shield and made it easier to sneak up on guards in level 4 (slaver camp at night)
  • Many improvements to level 5 tower approach and platforming section
  • Tweaks to level 6 (farm) visuals and gameplay (better pathing, a little better enemy balance)

Overgrowth Progress, Mid May

15 comments May 13th, 2017 by David Rosen

Project Status:

We released Steam Workshop support to everyone. We decided to kick it off with a 30% off sale, and a video with a voiceover you might recognize as Humble Bundle cofounder (and Wolfire alumni) John Graham. Lukas also had a big hand in making the video possible, by selecting the mods to showcase, taking all the in-game footage, and doing the final editing.

We hope to have Beta 4 ready for release next week. Beta 4 is one of the last betas before release from early access. Speaking of which - we now have a final official list of items to finish before we release from early access, and finally unveil the new Overgrowth campaign. It is getting a little shorter every day!

Team progress over the last two weeks:

(This is not a complete change list for all of Beta 4 - check the last two update posts for the rest of that!)

Gameplay/graphics changes:

  • Improved text wrapping in dialog overlays, and added initial version of "click to continue" prompt
  • Made camera not dip below lava surface when you die in it
  • Improved raindrop effect, made it more water-like and made droplets not streak when screen paused
  • Tweaks to spawn points in Magma Arena level to avoid some cases of spawning outside level

Modding changes:

  • Added steam workshop voting and marking favorites to mods menu
  • Small enhancements to advanced mod menu usability
  • Added depth of field cue triggers to dialog script
  • Added "defeat_optional" goal type in Overgrowth campaign checkpoints system
  • UX improvements for new prefab system ("save" doesn't require you to prefab a group yet, single items can be saved as prefabs)
  • Fixed some crash bugs and problems saving positions/bounding boxes with new improved prefab system

Performance improvements / Other bugfixes:
  • Added ability to log all assets that load while inside a level (so that we can add them to a list to pre-load)
  • Added checkbox to enable "simple water", to improve performance (turns off screen space reflections)
  • Various CPU and GPU performance improvements
  • Fixed bugs with creating OpenGL context in some cases on Windows
New campaign:
  • Level 1 major art and gameplay pass, improving the path through the level, signposting, and making it a bit harder to die
  • Extensive detail art pass on "forced fight" level, making it harder to escape, easier to fight in, and improving visibility of NPCs
  • Added new "water cave" level, and did a few detail art passes, including experiments with more dynamic water motion
  • Major art pass on 13b rat slavers level, improving path through level and adding a light platforming section
  • Minor gameplay pass on level 5, improving encounters with enemies and making the enemies a bit less placeholder
  • Tweaks to fog on rat slavers (13b) level
  • Lighting and water reflections tweaks in "forced fight" level (18)
  • Improved material properties/reflectiveness, and added ambient sounds in magma arena
  • Roughed up floor and added water puddles, and added fires for light/warmth in stands in cave arena level
  • Lighting improvements to water cave, volcano barracks, waterfall barracks, and volcano mine levels
  • Added more color-based signposting in water cave level
  • Replaced dialog in level 1-24 with new story pass
  • Hooked in new music to several levels
  • Worked on distinct character prefabs for the new campaign
