Kerbal Fishing Program

Start a career shipwrecked off Kerbin with no money and a fishing rod. Catch How to Fish's real fish, read from your own copy of How to Fish, to buy your first rocket.

After that, every catch has to be dragged to space on a cable, where it breaks free and attacks. Fight back with How to Fish's assault-rifle turret, or send a kerbal out on a spacewalk: mid-fight it becomes a first-person shooter with How to Fish's own SMG, pistol and shotgun.

• Kerbin: How to Fish's Beginner Lure catch (Cod, Pike, Piranha, Salmon…), boss: Sunfish
• Mun: the Standard Lure (Catfish, Clownfish, Seahorse…), boss: Blue Shark. Fish burst out of the dirt.
• Minmus: the Professional Lure (Tuna, Eel, Voxel Fish…), boss: Tuna
• Land on the Mun or Minmus and your engines seize until you hook that world's boss, just like How to Fish's islands.
• Kill a boss in space to clear its world and unlock the next world and a new gun.

Controls: Y to cast, hold Y to reel. Left mouse to fire, Y to switch guns on a spacewalk.

Needs: Kerbal Space Program 1.12 and How to Fish (Steam) installed on the same PC. No other mods. Single player.
