Add-on Sins of a Solar Empire II

Sins of a Solar Empire II: Harbinger

Description

The long wait is over as the deadly faction, the Eidolon, arrives in Trader space! Command the power of corruption, stealth and psionics to conquer all before you in this major expansion for Sins of a Solar Empire II.

The Vasari have been running for nearly 10,000 years from the 'great threat' that destroyed their empire. For 35 years, they’ve warned anyone who would listen about it drawing near…. Now, they have arrived: the Eidolon.

The Eidolon don’t value typical assets like other races, but they do exploit them as a way to spread their corruption more effectively. They seek only to corrupt those they encounter, transforming them into something else to empower themselves.

Features

  • Planetary Transformation: The Eidolon spread corruption across the galaxy to empower themselves and their worlds. As populations fall under the Eidolon’s influence, their planets gain corruption over time. Once a world has fully fallen, it can be shrouded, greatly expanding the upgrades that planet can support.

  • Unit Corruption: Corruption empowers Eidolon units in combat as well as weakens them. As an Eidolon ship gains corruption, its hull dwindles while its offensive power increases. Enemy forces can become infected by corruption, giving the Eidolon another advantage.

  • Null Weapons: Eidolon weapons are far more advanced than those of the other factions; and can negate shields and spread corruption against enemies.

  • Cloaked Ships: Subterfuge is one of the great enemy's sharpest weapons, as seen on the Kalizaeth Profaner support capital ship. New cloaking and detection systems let the Eidolon appear and vanish at will, enabling hit-and-run tactics that reward patience and punish anyone caught off guard.

  • Psionic Abilities: The Eidolon possess psionic abilities that allow them to seize control of lesser beings and drive Vasari ships into madness, firing on friend and foe alike.

  • Phase Echoes: Sometimes the dead don't die. Eidolon units infused with corruption may refuse to die and carry on the onslaught.

  • Discover more about the Sins universe as you explore ancient technology and research new Eidolon capabilities.
