Forts Update 1.22


G’day Forts fans!

Having taken a mid-year break, we’re back on our regular bi-monthly cadence with Update 1.22, which includes Quick Battle mode, Vulkan graphics, as well as the usual balance updates and improvements. Read on for more.


Quick Battle Mode

Three battles of instant action have been added in this new mode. Primarily aimed at onboarding new players, these missions aim to get recruits into the action fast, focusing on showing off the the magic of Forts’ physics and destruction, without having to worry about resources and build order. Let her rip!


Vulkan Graphics

Shifting to Vulkan has been a major effort to modernise Forts’ rendering. The ageing fixed-function OpenGL isn’t cutting it anymore. The primary motivation was to resolve issues with dated OpenGL drivers. It will provide users of Intel graphics a possible solution when they suffer from the glitched pixels bug, for example. Not only this, but it has proven to be higher performing, and relieves the CPU of significant work.

We consider the Vulkan renderer to be experimental at this stage, so it’s turned off by default. You can enable it by going into Options -> Video and checking ‘Enable Vulkan’. Feel free to send us feedback on issues at You can switch back to OpenGL at any time.


Balance Changes

Runway temperature gauge increases with each Thunderbolt launches.

  • Architect – Active Ability: Duration reduced from 30 to 24 seconds (-20%)
  • Architect – Active Ability: Takes 50% more damage to charge on attack and defense
  • Moonshine – Active Ability: 20mm Cannon EMP visual radius matches actual radius
  • Phantom – Passive Ability: remove damage hiding as it reveals the commander’s identity
  • Runway: Overheats after 7 rapidly launched Thunderbolts, or 3 Nighthawks
  • Upgraded Runway: Overheats after 8 rapidly launched Thunderbolts, or 4 Nighthawks
