Electromagnetic Awakening Party

Named for Moon’s Cryogenic Slumber Party, Alpha Omega’s quest is an argument with a computer: Rushmore, Broken Arrow’s terminal-bound AI, tests the twin crews against the facility’s five Core Values before opening the American Pyramid Device. Behind the pyramid door waits the Avogadro — revealed as Cornelius Pernell, the OSS handler transformed in a botched 1968 experiment — captured under a live nuke and shipped to Hanford, Washington, where TranZit’s players met him years earlier without knowing his name. The achievement text says it plainly: begin Nikolai’s Grand Scheme. Soloable.

Spoiler warning

This walkthrough reveals the map's finale. Continue only if you want to know how it ends.

Preparation

Before you start

Prerequisites

  • • The Nova 6 gas leak contained (generator defense and four house vents) — this opens Pack-a-Punch and wakes Rushmore
  • • Galvaknuckles for the broadcast step
  • • Sergeant A.D.A.M. authorization from Rushmore’s codes

Walkthrough

Step by step

  1. 01

    Wake Rushmore

    Contain the gas leak, then work the Emergency Broadcast System — a Galvaknuckled zombie, house-letter codes and punch-clocks — for Rushmore’s keypad code.

  2. 02

    The five Core Values

    Pass Rushmore’s trials in turn: escort a red Nova Crawler, talk Marlton into returning his stolen 115, install a server by telepad, repair six power boxes, and rebuild a broken A.D.A.M.

  3. 03

    Free Peter McCain

    The rebuilt A.D.A.M. releases McCain’s soul into the Elemental Orb — the OSS man’s story, open since Verrückt, finally closes.

  4. 04

    Open the APD

    Charge the pyramid’s soul canisters by destroying A.D.A.M. units; the device opens, and the Avogadro walks out wearing Pernell’s voice.

  5. 05

    The recapture

    With a nuke detonating overhead, fill four backup canisters mid-fight and lure the Avogadro back into the APD.

  6. 06

    Ship him to Hanford

    Transport the contained storm to Washington state and collect the Elemental Shard — then watch what Samantha does to Camp Edward.
