Now you've volunteered to go on the next mission, for reasons that are entirely your own. Your group is an amalgamation of characters just like the rest, but smaller than the others ever were in a bid to lessen the possible casualties. A scientist (ecologist/botanist, etc), a soldier/mercenary, a world famous explorer/archaeologist, a representative from the company and their guide, a woman of mixed Jivaroan blood.
Your objective? To find out what the hell is going on in the depths of the jungle and make it back out with your memories and your lives intact.

I think this one would be really fun to do as a group and I've left a lot of leeway character wise, so that the player can craft their own to their liking within the roles. My role would be that of the guide. It could also be done as a 1x1, with two principal characters and the two players taking minor roles of the other characters.
