- Level 1 The most basic type. Can be run by basic frigates. Only the most basic piloting skills are required.
- Level 2 While Mining and Courier missions may be run in frigates, Encounter is designed for cruiser hulls. You are expected to improve your abilities and learn how to fit out new ships.
- Level 3 As you specialize, you will need a battlecruiser, Mining Barge, or a medium-sized hauler. These missions go faster if you have trained for better ships and at least some Tech 2 fittings.
- Level 4 These require a battleship, an exhumer, or a large hauler. These missions can be time-consuming, but they offer large rewards. These missions require omega to run.
- Level 5 Mostly encounter (combat) missions designed for groups of players or capital ships and are exclusively located in Low Security space. Like level 4, these also require omega to run.
