Sandbox mode is exploding with new interactive content...
You're not alone anymore. AI aircraft traffic now populate the skies, flying your own planes. Provoke them, and they will fight back. Not only will the planes become hostile, but the sea-craft have defenses of their own as well.
This exclusive update is available only on Steam and includes the new race Lunar Arc, several enhancements to the designer, as well several bug fixes.
Complete update details are available on the SimplePlanes website.
