Diplomacy

In the diplomacy menu, you have access to treaty options such as cease fire agreements, peace treaties, and going to war. You also have access to intelligence options such as planet or ship vision, and you have access to an economic agreement via a trade alliance. You can also offer missions to allies, pact management, and the ability to just give away goods to anyone.

Player
There are four mission types that can be directed at specific players and for a set amount of time. You decide the mission type, who the target is, and how long the player being offered the mission has to complete it. You also set the reward.

Attack Planet - Sorted by Star, then Planet Type, then Planet.

Kill Ships - The more ships you add, the higher the relationship you need. Raising the reward, reduces the relationship needed.

Kill Civilian Structures - The more structures you add, the higher the relationship you need. Raising the reward, reduces the relationship needed.

Kill Tactical Structures - The more structures you add, the higher the relationship you need. Raising the reward, reduces the relationship needed.

Pirates
On the underground menu, you can offer missions to pirates. Unfortunately you can only offer an attack planet type mission, however, the more credits you put down, the stronger the fleet used to carry out the attack will be. They automatically only get 5 minutes to handle the mission so pay them enough to make it worth the effort, but not too much because the fleet that returns home waits for you there.
