Quick answer
Expeditions unlock at player level 20 and center on a 1,000 HP Payload. Up to four players share a 14-placement team limit while the leader chooses a route through defense, checkpoint, assault, elite and boss nodes.
Unlock and party rules
Expeditions unlock at player level 20. One to four players can join, and the team uses a shared 14-unit placement limit. Each unit brought into the mode has a one-placement limit.
Protect the Payload
The Payload begins with 1,000 HP. Enemies that reach it reduce that health, and the run fails when it reaches zero. Damage alone is not enough: the team needs early coverage and control that prevents leaks across the whole route.
Route nodes
Defense
Prepare for wave pressure and protect the Payload with a stable formation.
Checkpoint
Use the pause in pressure to assess resources and the next route branch.
Assault and Elite
Expect stronger enemies or constraints. Choose these nodes only when the team can handle the risk and benefits from the reward.
Boss
Save enough scaling and boss damage to finish before the Payload is overwhelmed.
Only the party leader can change the route. Agree on a priority before the branch appears.
Difficulty choice
The mode has three difficulty bands. Start with the level that produces consistent completions; a failed high-difficulty run can be worse progression than a clean lower run.
Team construction
- One dependable opening-wave answer.
- A scaling carry for later nodes and bosses.
- Economy that repays its cost within the run.
- Support or crowd control for route intersections.
- Coverage for any enemy type the chosen route introduces.
Expedition Hub
The Hub includes the Expedition Center, Research Lab, Armory, Gold Mine, Training Grounds, Resource Drill, Shop and Quest Board. Upgrade the building tied to the resource or performance bottleneck you encounter most often.
Recover from a failed run
- Record the node and wave where the Payload began losing health.
- Decide whether the cause was early damage, coverage, control, economy or boss scaling.
- Change one role or upgrade priority.
- Choose a safer route until the revised team is consistent.
- Increase difficulty only after the Payload finishes with a reliable margin.
