Pandemic Experience has two linked parts: personal trials and alliance trials. Members’ personal progress unlocks tougher shared goals for the alliance.
Personal trials
The player clears Hell Nurse levels. Each difficulty is a chain of 30 levels; clearing an available difficulty helps the alliance’s overall progress. If a solo squad is already taking heavy losses, ask for help and clear the target through a rally.
Alliance trials
R4 or R5 launches the shared boss fight. New difficulties unlock once enough members have cleared the matching personal trials. So it’s worth catching up stragglers first, and only then scheduling the boss fight.
Rewards are split into personal ones — for first wins and clearing a difficulty — and alliance ones, for taking part in defeating the shared boss.
What a member should do
- Clear the highest available personal difficulty as early as possible.
- Post in chat if you’re stuck on too tough a target.
- Watch for the R4/R5 announcement of the shared boss time.
- Check your squad lineup and healing reserve before the fight.
The number of available difficulties and boss requirements have changed after updates, so check the current thresholds in the event window. The core mechanics were checked against the Pandemic Experience guide on lastasylumguides.com.
