2. Create a backstory, environment, and three character descriptions associated with your
original game idea. How are these elements integrated and linked through a central
theme?

AHH
the backstory for my game is that humans were burning up their natural resources to fuel the thirsty overpopulated cities they have built in the future, tall skyscrapers flood cities and reach amazing heights, where the upper-class live, while slums made out of any scrap materials that could be found are on the ground  were most of earths people are stuck. While searching for any fuel source they can get their hands on humans discover a large ancient doorway with carvings and symbols unlike any civilization of earths.

a portal opens in the doorway leading to an ice covered planet, with large barren ice wastelands, and small villages built out of ice.

the inhabitants of the planet are large, bluky men, covered in thick fur, ranging from platinum white to black, roughly 5ft tall, these short people are remarkably strong and fast.

Although their forces are mainly consisted the people mentioned before, there are "elite" fighters amongst them, at a striking 7ft heigh minimum these large fur covered humanoids have tusks protruding from their mouths and are great threat to any who face them.

the human soldiers sent in to the war are equipped with slick black military gear, resembling plate armour if it were skin tight.
with powerful "plasma" weapons these humans are lethal killers.
