Premise
A space crew was sent on a mission to Mars, only to accidentally travel through a wormhole and crash on an unknown planet. The planet has breathable air, edible food, and enough water to last the refugees for years. However, the planet also has intelligent life, and their ruler enjoys forcing his subjects to fight to the death using techno-organic creatures called Megabugs. Now, the refugees must harness the power of the Megabugs if they ever hope to survive.
