Expeditions
An expedition guide built from confirmed Steam records and cautious upgrade advice.
Quick answer
Expeditions are confirmed by official store copy and Steam achievements. Treat them as a coin and upgrade system, with ACH_EXPEDITION_1M_COINS, ACH_EXPEDITION_50M_COINS and ACH_MAX_EXPEDITION_UPGRADES marking the current public milestones.
Current recommendation: Check expeditions whenever coin progress slows. Upgrade them when the cost clearly shortens your next hero, weapon, room or skill milestone.
What to do next
- 1
Open the expedition system once it appears in your run.
- 2
Collect expedition coins before making expensive upgrades.
- 3
Upgrade expeditions when the next milestone is coin-limited.
- 4
Use the achievement table to separate 1M, 50M and max-upgrade goals.
