The Manhattan Project Second StageThe box for Second Stage includes four smaller expansions to The Manhattan Project. They can be added to the base game individually or all at once.

  • Nations 2 includes seven more countries with unique special abilities.
  • Rocket Technology provides an alternative to bombers. Rockets work the same but require rocket factories to build and can’t be countered with fighters.
  • H-Bomb Technology doubles the victory points of a plutonium bomb but requires Lithium Deuteride as an additional resource.
  • Personalities are roles based on historical characters. They allow flexibility in the placement of workers, free espionage actions, and other benefits.
