How Outlast Trials amps work
Amps are bought from Dorris Ritter in the Sleep Room cafeteria once you reach Therapy Level 10. Each amp has its own unlock level and costs 2 vouchers. You can equip only three amps at a time, one from each group: tool, skill and medicine. Try a set in the loadout builder to see the unlock levels and voucher cost.
After a Relapse resets your upgrades, a permanent token keeps one amp unlocked; see the Relapse guide for how permanent tokens work.
