The Seraphim Quantum Arch is a campaign-only Seraphim structure seen in the final Forged Alliance mission - a trans-spacial Quantum Teleporter capable of letting massive numbers of objects teleport through at once (in this case, a huge Seraphim army). The final objective of the mission is to annihilate the Arch before millions of Seraphim pour through from their own dimension and conquer the Galaxy.
Trivia[]
- When spawned using the spawn menu (ALT + F2) the arch is unable to spawn units (in fact it can't do anything) meaning a separate entity in used to spawn the units.
