Slingshotter Handbook

Slingshotter is a rocket building and spaceflight simulation game.

Rather than controlling rockets in realtime, you specify their flight plan and watch how it influences trajectories in the long run, letting you plan missions that may last for many years.

You work under a tight budget that you spend by building rockets, and replenish by completing contracts. You must plan your investments in better technologies strategically, while completing long-running mission spanning years or decades.
