Unlimited Money Trick
This cheat will allow any player with access to a NEBULA class starship with the GEMINI EFFECT to a source of unlimited money.
To do this have your NEBULA class parked close to a ship yard with another ship (should be a ship which can be quickly dismantled, [any of the first three classes of ships should work fine]) parked close. Fire the GEMINI EFFECT onto this ship and once it hits have the cloned ship sent for dismantling. If done quickly enough you will gain money for the dismantled ship, without losing any ships this process can then be repeated as many times as needed as a continuous source of money.
