Chapter 5 · Demo 5 secret fight
How to beat Mutant
Reward: Secret boss completion
The Mutant is Demo 5’s secret boss. After Cassie joins, explore side paths instead of sprinting the critical path until you find the hidden arena. A warning scene plays—leave if you need more supplies.
Expect Demo 5 boss speed in phase one, wide arc pressure in phase two, and a brutal speed/damage mix under ~30% HP with a telegraphed finisher you must defend.
If you are playing day-one Demo 5, bring Pit farm gear: triple Defend+, multiple Call Cards, and a full food bag. This fight sits next to Finn McCool and Hatred on the difficulty list.
Exact drop tables were still stabilizing right after launch—we will update this note once the reward is fully confirmed in-game.
