Osiris is under attack. Unknown forces have infiltrated the network, leaving control nodes scattered throughout the system.

Deploy the Cypher. Purge the corruption. Restore Osiris. Save us all.

SPACE CORPS // OSIRIS ACCESS LEVEL 7

SECURE TRANSMISSION - CLASSIFIED

Incident Designation: OS-INF-1

Origin: Osiris Core Network

Status: Containment breach detected

Threat Level: Escalating

As the population celebrates the destruction of the Galactic Plague (see Mission REX), it seemed life would return to normal.

But soon came the first attacks on Osiris itself.

Osiris - the system that underpins life across the galaxies - is now under direct threat from an unknown source.

Corruption spreads through the network, severing command links and destabilising containment protocols. Autonomous repair subroutines have failed to respond.

If Osiris fails, we all fail.

There will be no order. No justice. No life.

Only one countermeasure remains: Deploy Cypher.

Reconnect the nodes.

Protect the mainframe.

Purge the infection before it consumes the system.
