Superportal



"...And if that portal reaches critical mass..."

"It'll be the Seven Hour War all over again...Except this time, we won't last seven minutes!"

A Superportal, as its name denotes, is a massively powerful and large portal conjoining two separate locations. Compared to a normal portal it can be used to transport huge volumes of mass across large distances. Often initiated by cataclysmic quantum events, such as a Resonance Cascade or the meltdown of a Dark Energy Core, the Superportal can have catastrophic consequences at both ends.

Additionally, superportals spawn catastrophic Portal Storms in the surrounding area, making it incredibly dangerous to anyone near the Superportal. The only Superportal known to exist was created in the wake of the Citadel's destruction. Because the explosion caused a chain-reaction that disabled all other reactors on Earth as well, the Combine were forced to sacrifice the Citadel in an attempt to create the Superportal and reestablish connection to the Combine Overworld.

Notable Events

 * Due to the Resonance Cascade which occurred during the Black Mesa Incident, the Combine were able to create a Superportal large enough to transport their entire army to Earth and overpower the Human race during the Seven Hour War.


 * At the end of Episode Two, Arne Magnusson's rocket was launched in an attempt to sabotage the Combine Superportal while it was still in it's infancy. The rocket activated at or near the portal and linked up with the satellite array that was established at Black Mesa and that had presumably lain dormant until then. The rocket tapped into these satellites and used a "Xenium Resonator" to neutralizes the portal. It is uncertain what the fate of the rocket was, which may have launched along with Dr. Kleiner's pet Headcrab, Lamarr.
