You have been selected to pilot the advanced experimental mecha 00-ARETHA into battle, as a last ditch offensive against an alien invasion. The battleship of a machine is not only armed to the teeth with all manner of weaponry, it also has the latest advancements in defensive technology, culminating in it's incredibly potent Primal Armor; A nigh-impenetrable force field of radioactive particles, projectable for use in offense and defense. Its boosters can propel you at multiple times the speed of sound, as well as change direction and accelerate in an instant. Your task is to be the final bastion to allow the retreating human forces to regroup, and spearhead the counter-offensive. You will ride into battle against the alien threat as the lone pilot of ARETHA, and meet them with swarms of bullets, missiles, plasma, and human fury.
The mission begins with the enemy fleet in Earth orbit. Parasite craft detach from the main ship, and swarms of dropships heading towards the surface signal the start of another offensive...

"This is the captain speaking." His voice crackled through your headset. "We're about ready to launch our fighters. They'll provide you with support fire, but you'll be doing the heavy lifting out there, Pilot." Rushed to the hangar, you quickly hop into the human military's magnum opus; the 00-ARETHA.
As the neural link activates, you stretch and feel the massive mecha's arms as if they were your own. Despite your body feeling the size of a small skyscraper, you are in complete control of your movements. Your right hand clutches a hulking quintuple minigun, and your left a plasma railcannon twice as long as you are tall, barely fitting in the hangar of the supercarrier transporting the ARETHA. Through the neural link, you become aware of numerous smaller auxiliary weapons placements around the mecha. Point defense guns, vertical launch missiles, drone swarms hangars, laser turrets, all complimented by copious amounts of flares, chaff and electronic countermeasures. As no less than three massive high-efficiency nuclear reactors spool up within you, you take control of the mechanical beast and slowly lumber to the launch platform. Below you, the aliens lay siege to the planet Earth, a massive front of their forces marching unstoppably across the Asian continent. The odds seem insurmountable.
Klaxons blare across the hangar, and your towering mecha is moved forward for launch. "CLEAR THE DECK!" The captain screams over the intercom. LAUNCHING ARETHA IN T-MINUS 3..."
You grip the controls.
"2..."
Sweat beads under your suit.
"1..."
The faces of your friends and family flash through your mind.
"0! LAUNCH!"
In an instant, the ramp ARETHA is attached to is accelerated magnetically outside of the hanger at breakneck speed. Once you clear the supercarrier, your own boosters activate, jets of white hot flame erupting from your back and limbs. ARETHA accelerates to hypersonic speeds towards the ground, directly towards the advancing alien front, thick with xeno soldiers and vehicles. You hurtle towards the surface, a fireball of human hatred and ballistic retribution.
