Stellaris: Federations Steam

NOTICE: Activation key must

connection.

The supreme art of war is to subdue the enemy without fighting.
With the Stellaris: Federations expansion, players can extend their
diplomatic dominion over the galaxy like never before. Use every
trick in the book to gain an edge on friend and foe alike, with a
host of new options to influence, manipulate, and dominate without
firing a shot.

Features include:

• Expanded Federations: With expanded diplomacy capabilities,
  players can build up the internal cohesion of their Federations and
  unlock powerful rewards for all members. Whether you join a Trade
  League, Martial Alliance, or Hegemony, membership can be extremely
  advantageous.
• Galactic Community: Unite the space empires with a galactic
  senate that can vote on a wide range of resolutions to drive
  legislative agendas. For example, players can pass a resolution to
  increase commitments to collective defense or funnel profit towards
  wealthy elites. Members can also sanction those who defy the
  community, and enact a single galactic focus. Sway the senate to
  position yourself as a leader, trading favors and maneuvering,
  doing whatever it takes to gain influence among schemers.
• Origins: Each empire has a story that shapes its path. Give
  your civilization deeper roots with the new system of Origins. By
  choosing an Origin, players can flesh out their empire’s background
  and alter its starting conditions. Whether it’s Void Dwellers who
  have abandoned their homeworld to live in perpetual orbit, or a
  society that worships and protects a powerful Tree of Life, you can
  lay the groundwork wisely for the seeds of your empire.
• New constructions: Construct glorious new projects for your
  empire like the Juggernaut, a massive mobile starbase that provides
  a moveable repair base even in enemy territory, or the Mega
  Shipyard, a new megastructure that can churn out fleets with
  incredible speed. Offering both tactical advantages and a good dose
  of shock and/or awe, these are sure to be an asset to any space
  empire.
