Galactic Fist of Legend: Volume 1

In the year 2018 a bright star appeared near Earth. Humanity as a whole was briefly introduced to a race of beings far beyond their understanding. During that brief interaction a proclamation was made, Defeat the Grand Emissary or become the eternal slaves of those who had arrived at Earth.

The only chance for victory was for people all across the globe to make a choice. When prompted to become a champion and a play a bizarre game of life or death they could choose yes or no. Those who chose no, went about their lives afterward. All memory of the event was lost despite the fact that their very existence as a free species hung by a single thread.

Will those who said yes manage to survive the horror of the game and become strong enough to defeat the Grand Emissary. Can one of them become... The Galactic Fist of Legend.

Also, it's a comedy with significant parody elements. Pretty obvious, right?

This litrpg story takes place in a setting that involves hopping between worlds. One moment the protagonist is fighting zombies, and the next he is facing down platform hopping challenges in a world where a single misstep could send him plummeting down through what appears to be an endless sky. Part of a multiverse project known as Project Scott, it features a main protagonist who's name is similar across multiple books but who is not the exact same character each time. It is a labor of love, and of goofy humor. Other stories in the project include Freelance Saga, Galataea Crystallim, and Origin ARS.
