Open the map by following the objective markers from spawn, then unlock one of the two early barriers and push through the island path until you reach the broken power-line objective. Repair both broken power switches on the two sides of the map, and the full power will come on once both are fixed.

Fast route

  1. Leave spawn and follow the on-screen objective marker.
  2. Open one of the first barriers in spawn.
  3. Move through the fishery island path and keep opening the route ahead.
  4. Reach the area with the broken power lines.
  5. Repair the first switch, then travel to the other side of the map.
  6. Repair the second switch.
  7. After both are repaired, the power is fully restored.

Tips

  • The order of the two sides does not matter.
  • Each repair takes a few seconds, so clear nearby zombies before interacting.
  • Once power is on, the objective updates toward Tyro’s Head and the Pack-a-Punch setup.

Extra note

A guide posted on the same date also says the power step is part of the larger Totenreich setup chain that leads into Pack-a-Punch and the main quest.

TL;DR: Open the map, reach the two broken power switches, repair both, and the whole map powers up.
