Thank you for your time! There is literally no onboarding at the moment. One of my friends said it feels more like an escape room than an artillery game lol. I should definitely fix that.
Yes, there is a target that can be destroyted in the game, and you can triangulate its position by asking your beacons (airship allies) for their distance to the target. There are multiple beacons, so you can use them to triangulate both your own position and the target's position. Then, you have to find the correct charge and elevation using the range tables in the manual.
There are some other tools that can help you geolocate yourself: Topographic map, and the scanner. Beacons can also scan the terrain beneath them and send the image to you.
