The Game
MechRunner is an endless-style action game mixed with fast and furious mode-changing mech action. You're always moving forward, tracking down lethal O.S.O. forces — but you're piloting a giant robot capable of some serious destruction.
Heat-seeking missiles, heavy-caliber bullets, laser cannons and concussion bombs meet destructible buildings, debris-littered streets and plenty of sliceable enemies.
The XP-41
The mech you control changes between two modes for different styles of combat and control. Each has its advantages — and its weaknesses.
A little slower and less maneuverable, but armed with heavier weapons that break through enemy defenses, take down heavier enemy types and inflict more damage.
More agile, with faster dodging, strafing and fire rate — plus a pair of swords on the robot's arms to slice through disabled enemy mechs and deflect incoming attacks.
The Story
On June 30th, 1908 a mysterious explosion took place over the Tunguska River in Siberia, Russia that wiped out trees and wildlife for over 800 square miles. To this day it remains the largest “impact event” in our planet's recorded history.

In the years that followed, dozens of scientific expeditions to the site attempted to explain the disaster but failed to come to any conclusions. In the mid-1940s however, a team of scientists from the Russian secret service visiting the site stumbled upon the wreckage of an alien spacecraft containing technology that far exceeded our own. The KGB set to work harnessing this mysterious new power source and created a new secret weapons program — the Division of Advanced Weaponry, or “O.S.O.”
They thought they could control the new power they'd discovered, but it began to do more than run their machines. It began to drive the men working on it mad. The man in charge of the O.S.O., General Yuri Petrakoff, seemed particularly affected — and on April 14th, 1949, Petrakoff launched a full-scale assault on Europe.
One of Petrakoff's lead engineers, Jesper Teterev, went AWOL and left the program early, wary of what was happening there. He went to live in secret with his sister, Isabel, and niece, Allison. While in hiding, Jesper — with the help of budding engineer and pilot Allison — was busy building his own mechanized war machine, the XP-41, certain it may be needed one day to stave off the O.S.O.'s evil creations. Jesper was right.

Characters
One of Russia's foremost rocket scientists, Jesper was heading up the space program when he was reassigned to the O.S.O. He had an instinctive understanding of the alien technology that his peers could never match — but he and General Petrakoff did not see eye to eye. Much of the advanced tech that leaked out of the O.S.O. was the result of Jesper's unwillingness to hoard their discoveries, and when Petrakoff found out, he had him imprisoned in the factory.
In January of 1948, Jesper escaped and did his best to disappear. But he knew trouble was coming, so he saved some of his newest developments and most powerful technologies for a weapon of his own design, one that could fight Petrakoff's army: the XP-41.
Jesper's niece, a pilot and a budding engineer in her own right. She remembered her uncle for his fun inventions and amazing ideas — but when he came to live with her and her mother, he seemed panicked and feverishly busy. One day Allison followed him to his warehouse and saw the XP-41: the most amazing, and most terrifying, machine she'd ever seen.
Unbeknownst to her mother, Allison began working alongside Jesper, learning to pilot the machine. She's untested, but she knows the XP-41 inside and out — and as long as she can collect more protoenergy, they can keep modifying and repairing the mech to stave off the O.S.O. attack.
Leader and founder of the O.S.O., driven (more) insane by prolonged exposure to the alien technology recovered from Tunguska. As he saw what protoenergy could do, he grew guarded and secretive; the facilities became a literal prison, and he built an army loyal not to Russia but to him.
Spiraling into madness and seeing the whole world as a threat, in April 1949 he launched a full-scale invasion of Europe — intending to subjugate the world, or destroy it in the process.
