Carefully balance mobility, firepower and armour in a dedicated tank designer. Then uncarefully put them to the test in a series of combat scenarios progressing through the ages of the tank. Here, your limit is what you can fit inside your hull and turret while still being able to move forwards.

Hi all, There's a build up on the experimental branch which adds Christie spring suspension. Compared to torsion bars, they're cheaper, more space consuming and they run up the sides of the hull instead of across the width, letting you…
Patch notesHi all, The build on the experimental branch is now stable. With a game engine update which brings the game up to speed with 4 years of engine changes and fixes. This is necessary for some engine changes and fixes needed for the GUI…
MushyHi all, There's a build up on the experimental branch with a game engine update, bringing the game up to speed with 4 years of engine changes and fixes. This is necessary for some engine changes and fixes needed for the GUI overhaul. A…
Patch notesHi all, The experimental changes are now on the stable branch. Changes Two new modes for the armour overlay: Absolute - A heatmap of the raw thickness of each plate Effective - A heatmap of the effective thickness of each plate, taking…
MushyHi all, The experimental changes are now on the stable branch. Immersion pass Did some work on the visual and sound effects in an effort to improve gameplay simply by removing immersion-breaking effects. I'd say it was a success and I'm…
MushyHi all, There's a build up on the experimental branch with dynamic vehicle centre of mass and a pass on many of the effects in the game. Hopefully these changes let you feel a bit more immersed in battles!…
Patch notesHi all, Pleased to announce that the four month overhaul to vehicle movement is now stable. Track physics has been moved off of the PhysX engine into a custom solution - opening the black box to allow your design decisions to have much…
MushyLeaf spring suspension stiffness reduced by 20% Removed padding from the torque threshold required to upshift. Makes the driver less hesitant to upshift. Improved the accuracy of the resistive torque estimation used in the gear shifting…
Patch notesReduced lingering exhaust thickness by 1/3. Fixed another cause of modded engine tech allowing infinite RPMs. Constant mesh is now limited to interwar onwards. Synchromesh is now limited to earlywar onwards. Improved bogie articulation on…
Patch notesFixed grade resistance not being applied to the powertrain correctly, resulting in unrealistic performance moving uphill. Slightly reduced drifting. Exhaust colour and density now changes with the amount of fuel being burned. Increased…
Patch notesLowered the coefficient of friction for tracks from 1.2 to 0.8. Reworked lateral traction to use the same model as longitudinal traction. Affects turning behaviour and creates more drifting on lighter vehicles. Reduced vehicle sliding on…
Patch notesFixed instability sometimes caused when switching from drive to reverse and vice versa. The driver will no longer downshift if the resulting engine speed would be above the rev limiter + the expected RPM drop from shifting. If the driver…
Patch notesAdded 3 transmission mesh modes: Synchromesh (default): Easier speed matching, allowing higher gear steps in some cases. Bigger and more expensive transmissions. Slower to engage gears. Constant mesh: Requires precise speed matching by the…
Patch notesReworked driver shifting behaviour. Downshifts are now based entirely on torque, instead of speed. Upshifts consider whether speed can be maintained at the new gear, so the driver can upshift on inclines again. Viscous drag on the sprocket…
Patch notesFixed tanks sliding at stand-still, introduced with the tension changes. Fixed track belts not colliding with objects above the track (actually fixed this time). Engine idle RPM is now automatically configured. The engine shift range used…
Patch notesWarnings are now displayed for potential issues with transmission setups. Fixed incorrect speed limits on transmissions with top gear that's not 1:1. Fixed vehicles rolling backwards without any inputs, more noticeable on some vehicles.…
Patch notesTension around the sprocket is now simulated more accurately, track tension will shift throughout the track when transitioning between drive and reverse. Shouldn't affect vehicle performance except for the time taken for the sprocket to…
Patch notesThe driver can now go below the downshift if needed for a large gear step. This fixes some designs not upshifting. The driver will no longer downshift if the engine is accelerating or the last shift was under 3s ago. This stops an…
Patch notesShifting is now based on track speed instead of engine speed. The driver won't upshift if the resulting upshift RPM is below the downshift target and vice versa. Prevents the driver upshifting and immediately downshifting again. The…
Patch notesRewrote twin transmission driver behaviour with the new approach used on clutch braking, allowing for improved gear shifting. Should be a bit more responsive now.
Patch notesThe driver starting in 2nd gear on launch is now an option in the steering wheel properties. (Off by default) Fixed transmission aux gear multi stage threshold not saving correctly. Fixed the driver not always applying the requested…
Patch notesHi all, Here's a full rewrite of clutch braking driver behaviour for the movement overhaul on the experimental branch. Allows for more complex behaviours like speed matching while shifting, as well as cleaning it up on my end. Changes…
Patch notesHi all, Sorry for the wait! This was a tricky one There's an experimental build of 0.2.51 up on the experimental branch {STEAM_CLAN_IMAGE}/40992535/9057602a469d43fc43528968296953d859829b68.png This time powertrain and track behaviour have…
Patch notesHi all, 0.2.50 is now stable! Bringing with it the new cost system and a host of transmission changes. 0.2.49.4 has been moved to its own branch - in case you weren't quite done with it. Cost system This update introduces a new cost system…

MushyHi all,Here's the reconsidered post-0.2 roadmap, as promised:Quite a radical reorder there but hear me out.The reorders are driven by a desire to focus on core gameplay. Focusing on making a polished heavy-feeling and realistic single…
MushyHi all, Pleased to announce that after 30 months in development, 0.2 is now considered more stable than the stable branch (by quite a bit too!).0.2 is moving to the main branch, where it will become the default experience. 0.1261 (the…
MushyHi all, Final patch for the experimental branch to wrap up the 0.2 beta. A separate post on that to follow. This patch removes the placeholder models for turret rings and traverse drives. Traverse drives are now a concern when designing, as…
Patch notesHi all, Here's yet another week of fixes for the experimental branch (0.2). Fixes When placing a part, selecting a new part for placement will now replace the current placement. Cannons now automatically assign sights if they don't have…
Patch notesFixed stuttering outside of the editor with high vehicle counts. Fixed a recent cause of vehicles not loading.
Patch notesFixes Fixed freeform hole generation missing faces. Fixed freeform hole generation having inverted face directions. Fixed custom decals/paint not loading if the file name contained spaces. Fixed grid snap 0 causing sliders to break…
Patch notesHi all, Here are some more fixes for you, focusing on freeform this time. Fixes Plate structure moving, rotation and scaling can now be done in global space. Fixed the freeform slope tool creating extreme results on almost flat surfaces.…
Patch notesFixes Custom decal and paintjob paths are now stored relative to game's Documents folder. Fixed the decal URL field not updating when changing the decal graphic. Raised the minimum torque of the transmission manual torque config sliders…
Patch notesHi all, Quick fixes for Tuesday's patch and some slow fixes for older issues + some improvements to flameouts I've been eager to do. Fixes Fixed AI gunners not firing if they couldn't see the lowest point of their target vehicle. Gave the…
Patch notesHi all, This update rewrites some crew systems, making them more stable (long-term), tidier on my end, and easier to introduce new types of roles with. It sets the groundwork for the return of commanders and radiomen, as well as multiple…
MushyFixed spare wheel hit boxes not matching their wheel size. Fixed multiple track editor GUIs appearing with the track selected. The steering wheel is no longer painted. Fixed certrain track edit sliders from being unresponsive. Fixed spare…
Patch notesHi all, Quick fixes for yesterday's patch. Reduces the size of driveshaft junctions, to help with the new angle limitations. If the limitations still aren't for you, the reimplemented place anywhere cheat will let you disable them. Fixed…
Patch notesHi all, This patch fully reworks the editor hitbox system, used to detect part selection and obstruction. Fixes the fundamental bugs and poor performance of the previous system, and cleans things up on my end. This update is for the…
Patch notesHi all, Here's some AI improvements for 0.2 (experimental branch).Should make them behave themselves more and shoot you in the back less.ChangesAIs now check their line-of-fire for friendlies.AIs now avoid driving into other tanks. This…

Patch notesHi all, As mentioned in Tuesday's patch, 0.2 is at target feature parity with 0.127. So all work will now go into fixing bugs, improving stability, and refining the new 0.2 features. 0.2 is moving to the 'experimental' branch and the…
MushyHi all, Here's the final major 0.2 alpha patch before it enters beta. We'll move to the experimental branch in the next few days, where 0.2 will be stabilized and polished. 0.127 will be moved to its own dedicated branch where you'll be…
MushyHi all, Continuing the implementation of missing features from 0.127 to 0.2. Cannon Linking Cannons can now have their firing mechanisms linked, allowing one gunner to fire multiple cannons at once, or with a delay between them.…
MushyHi all, This one reimplements all missing scenarios from 0.127 over to 0.2 - with a few tweaks to take advantage of the flexibility added by the rewrites. This update's for the 0.2 alpha, you'll have to opt-in to play it…
