Your learning route

This guided horizontal-release lesson is the first part of the upgrade. The other Academy lessons and six battle drills remain available in their current form.

Horizontal release · positions, components, G.U.E.S.S., prediction and evidence. Guided pilot available now.
Angled launch · resolve speed and angle; shared time and the apex.
Different landing heights · choose the future descending crossing.
Gravity comparison · Moon 1.6, Academy 2.0, Mars 3.7, Earth 9.8 m/s².
Battle firing solution · actual muzzle coordinates, limits and private orders.
Simultaneous launch and movement · any number of cannons may move instead of firing; automatic winch.
Terrain and counterattack · obstructions, craters and changed launch geometry.
Carrier operations · deployment, horizontal ordnance and return to base.
