Forte of the Glacier City
Seeking escape from the cold and the constant fighting, the group discovers a massive city buried under an ice canopy—the ruins of Denver. They take a much-needed break to explore. During this respite, the attraction between Stick and Aisha grows, while the relationship between Rey and Houquet becomes more strained. Their peace is short-lived. An Inbit prince, Batra, tracks them down and launches a surprise attack with his new Gamo mecha. To survive, the team collapses the city's icy shell on top of the Inbit forces. As they flee the crumbling ruins, Jim triggers a final, massive explosion, destroying the city to ensure no enemies escape.

The story takes place in the 21st century. Due to the fact that pollution was becoming a major problem, scientists had developed the use of hydrogen fuel called "HBT" as an alternative to fossil fuels. At this time humans have colonized Mars in search of new place to call home as a result of overpopulation. In the year 2050, a mysterious alien race called the Inbit invaded the Earth. Unable to fight the Inbits, Earth became desolate with only a few pockets of human beings scattered throughout the planet. Many of the refugees escape aboard a few remaining shuttles to seek shelter on the Moon. The Inbit set up their main base of operations in the Great Lakes area of North America called "Reflex Point".
