Mission types with rewards given for completing waves – particularly Defense, Survival, Excavation, Interception, Infested Salvage and Defection – rotate through pools "A", "B" and "C" from which a reward is given, depending on the wave. Typically, the pattern is two rewards from A, one from B, one from C, repeat (AABCAABC...). A potential rotation reward is given to players after completing 5 waves in Defense, 1 round in Interception and Infested Salvage, 1 successfully defended excavator in Excavation, or every 5 minutes spent in a survival mission.

| Excavation | Artifacts recovered | 1, 2, 5, 6, ... | 3, 7, ... | 4, 8, ... |
| Interception | Messages decoded | 1, 2, 5, 6, ... | 3, 7, ... | 4, 8, ... |
| Infested Salvage | Manifests decoded | 1, 2, 5, 6, ... | 3, 7, ... | 4, 8, ... |
| Defection | Squads saved | 2, 4, 10, 12, ... | 6, 14, ... | 8, 16, ... |
Notes
Failed excavations in the Excavation mode do not count towards reward rotation. That means if, for example, you successfully excavate 2 artifacts, but fail to protect the 3rd excavator, the 4th one will still provide a reward from the B, not C, rotation - only successful excavations count.
