Plastic Explosive is one of the items that could be bought at the Emendation Station 3500, at $5000 each. Press C to use. When used it blows up a 5x5 area around the pod. This destroys stones, lava, and gas pockets without harm to yourself, but will also destroy minerals and artifacts.
As Dynamite only costs $2000 each and blows up a 3x3 area, Dynamite is usually more efficient and controllable, although Plastic Explosives are far stronger for the Ending.
Trivia[]
- The C hotkey may be a reference to the well-known C-4 explosive, which is a type of plastic explosives in real life.
