Horsefly Updates 113909 / 113895 / 113794 / 113783 and TITANS 1v1 Ranked Mid-Season 4 Winners

Hello Commanders,


That’s the sound of the Horsefly exploding its way into Planetary Annihilation, the newest addition to your arsenal.

Found in the Advanced Air Factory and armed with rapid-fire cannons, it strafes targets to remove all the pesky AA (and fabbers) from the vicinity, while tanking return fire with its heavy armour. Conduct your bombing campaigns in peace once more. It will attack the land, it will attack the sea, and in a pinch it can even attack air.

For those of you running on Linux we have some good news: Planetary Annihilation will now work with Mesa when run within a Steam Proton environment. We continue to work with Coherent Labs on the native Linux issues.

We also have prizes to give out. The mid-season arrived, and with it the tightest contest for first yet. When the fires died down it was KillerKiwi who stood victorious among the wreckage. Congratulations to them, US$500 is on its way. We’ve also listed below the individuals from each league claiming the US$100 activity prizes, if you’re on that list and haven’t been contacted please raise a ticket with support. As ever, there will be further prizes issued at the end of the season (2019-10-25 00:00 UTC), so keep on fighting!

Some further adjustments to the air game have proven necessary, with Kestrel gunship damage slightly reduced. Flak has been adjusted to place greater emphasis on its splash, making it more of an anti-horde unit, while reducing its single target damage. The Storm mobile flak has also been given the ability to tilt its gun forwards and backwards to fire off a shot earlier against attacking bombers and to help it land shots in the middle of Kestrel gunship hordes, but it remains vulnerable when approached from the flank. The Angel advanced air support platform and Mend advanced combat fabricator can now auto reclaim the wreckage of your enemies or fallen comrades.

Finally, we’ve been improving various technical bits and bobs to continue enhancing performance, especially with loading of the UI and mods. SVG fonts are dead too. What’s an SVG font you ask? Look, it says SVG font in the technical notes, that’s all I know. Let’s mourn their passing together.

PA was built with modding in mind, and while we appreciate the contribution that mod authors make to our game, please remember that running mods can sometimes lead to unexpected defects and crashes, especially after a new update.

Before reporting any issues please ensure you test the game without mods enabled. Defects with mods should be reported to mod authors in the PA forums thread for each mod.
