Combat & identification

Reported fight approach

  1. Prepare radiation protection before approaching the reactor. A blue-and-white warehouse beside the tanks is a reported encounter location.
  2. Clear the dark-suited guards at the entrance, then look for the yellow-suited Chemist near the rear bay, forklifts and blue drums.
  3. Withdraw through the entrance to repair armor when needed. Loot quickly; radiation remains dangerous after the kill.
