It's simple, really... heroes and other "good guys" have been brought to a remote tropical island covered in dense jungles. To make matters worse, villains and bounty hunters from all over the world have gathered to hunt them down.
Some sort of energy shield has cut off the island from the rest of the world, so that means that escape is virtually impossible.
All "good guys" have had their weapons/equipment taken from them. It is located in a storage facility in the center of the island.
The "good guys" will wake up/begin their journey on the outer shores of the island. The "bad guys" can start from wherever they want.
It's a fight for survival.... Have fun.
I'll try to get the RPG itself up sometime tomorrow.
