The Universal Union: Invasion of Equestria

Rebellion filled the streets as Gordon assaulted the Citadel. The rebels assisted Gordon on his way to the Citadel, with Eli freed from Nova Prospekt, the rebels had enough morale gained that they could fight on, and on, without fear of death.

Gordon Freeman had already made his way to the top of the Citadel, and the battles were at their peak. Both sides suffered unaccountable losses. The planet's main hub being under such struggle caused the fall of other cities. Every city was heavy in battle.

The Combine made one fatal mistake after the Seven Hour War. They didn't prepare for rebellion at all. Their weaponry, terminals, locks were all easy to access with a few good rebels.

The Combines final fight was nearing the end. Soon, they'd be cut off from the Union. They would fall, leaving the ashes and remnants of Earth to pick at the remains, in hopes to reestablish society and replenish their old way of daily life, before the Seven Hour War.

"Warning: Core reprogramming detected.", was heard being blared by the Citadel loudly.

Humanity fought like no other species. Humans never surrendered, they fought until they achieved victory.

They never truly gave in. Whether a political figure demanded it, or another nation fought them. Would they surrender at that?

No, they wouldn't surrender at all.

So why now? Why would they give in now?

Strider's fired blindly, as their final fight was drawing closer and closer outwards to an end.

The city shook, as the citadel's top sector was completely annihilated.

The Union was cut off from Earth.

Equestria could no longer receive more reinforcements.

A black hole seemed to be forming at the top of the Citadel, as "Warning.. Bypass detected..."

"Alert.. Alert.. Alert..", had echoed repeatedly, as the Citadel came nearer and nearer to its final moments.

Gunfire continued on, and on. Explosions continued.

Nobody would stop, the battle had raged on for hours too long already.

The Combine struggled to fight against the will power that humanity had established.

The citadel was at its end, as the Combine continued fighting, dying for the cause that was carried universe to universe. Bright, white lights seemed to fly through the hole, as it began to glow bright before exploding.

The pure black devilish looking portal seemed to explode shut, as the middle and bottom of the Citadel then exploded, sending red debris, flying all around the city, and even out of the city, destroying everything in its way, smoke filled the area, the blue sky was now coated coal black.

Explosions echoed, debris collapsed all over the city after being shot outwards from the explosion of the Citadel, nothing could've survived the hellish collapse of the Citadel.
