The Portal storms are rapidly spreading and have already taken New Mexico and most of its surrounding states. The US military is scrambling to mobilize its forces.

Situations

Crisis Relief - An US army National guard Relief force coming to assist the US army forces present in Phoenix.

Civilian Side - Get the out of Phoenix.

Combined arms - USMC Marine Recon Detachment arriving in Phoenix along with a group of UN soldiers.

Missing in Action - A SOF soldier waking up from a helicopter crash

Coming sometimes. (Not soon, If at all.)

Evacuation - Take apart of a Ranger regiment evacuating civilians to the underground sections of Washington D.C in the final days of the Portal Storms.

Final days - A civilian in Washington D.C trying to get underground right after the Evacuation

After the Black Mesa incident and before the 7 Hour war, a time period called the Portal Storms began. The Portal Storms are a result of the Resonance Cascade.

A Valve employee has said that the Portal Storms lasted days. In my head canon the Portal Storms lasted about 2 weeks and spread over the entire world and inflicted over 50 million Military and civilian Casualties worldwide. Although this is not apart of the bot. You can make up your own headcannon and use that with this.

I'll update the scenarios sometime in the future. They are not very good.
