Are there any cheats like -MUDD I really hate not having credits and having to work for them I'd rather just be jumping straight into the diplomacy combat and Starship building.

Diplomacy and combat are not implemented yet in the game, and shipbuilding is possible but doesn't take credits yet. The game is still in alpha.

There is a cheat in the game, but it's nothing like -MUDD. I think if you press F12 you can reveal the whole map, but only for the rest of the turn.

As .Iceman said, the game is still at a very early stage of development; Diplomacy is still a work-in-progress, and the Combat engine is yet to be completed and merged into the game. Other than exploring, there is no need for ships, and since there is no instant-build feature in the game (And never will be, there will instead be a feature to increase construction speed by a maximum of 10% by paying your workers to work overtime) there is little need for credits at the moment. The maintenance costs for the ships haven't been fully implemented either, although i'll be personally working on this in the next few weeks and months.
