In the year 2041, the Droods managed to find a way to synthesize metallic hydrogen, a strange form of hydrogen that had a high chance of being inside Tydos and gaseous exoplanets. Research for this fuel had been going on for years, but only in that year was it possible to synthesize it.
In 2050, after several not-so good or safe earlier engines, it was proposed to combine Cesium with hydrogen, so that magnetic confinement could be carried out, creating a lightweight and much "cheaper" way to make an engine using MH2. That's how the OPIPE-X10 was developed. The best engine ever created by Droodkind. With an abbreviation that may or may not mean OverPowered InterPlanetary Engine, the engine is currently in the certification phase to ensure it does not increase the percentage of Cesium in Droo's atmosphere by 30%, but it is already available in simulators like SimpleRockets 2.

Half OP engine, it can make you go to cylero in about 2 days and orbit it... with just the amount of fuel in the tank that comes with it... without using any launch vehicle.

Doesn't look like anything OP, right?

Anyway, it's just a magnetic confinement motor for you. so use it.

*except of course the in-game price that you have to pay me in 2 hours due to the terms of the contract that you did'nt read at all. Good luck getting the money. You can use it normally for those two hours. Meet me on Jupiter's core to give me the money. Goodbye.
