The New Empire campaign consists of three types of missions, each detailed on its own page.
Mission Types
Colony Missions — Establish and defend a colony on the campaign map. These are the primary missions that grant Empire Points and unlock adjacent missions.
Scouting Missions — Smaller missions that each unlock a hero upgrade point and a news article chronicling the downfall of the ancient human civilization.
Swarm Missions — Defensive engagements against an infected swarm blocking a path on the campaign map. Completing them rewards Empire Points and unlocks the mission they were blocking.
