From the Back of the Book:
The GI Joe Team must win a deadly biological game in OPERATION: JUNGLE DOOM.
In the underground Briefing Room of the Pit, Hark gives you and a grim GI Joe team the news: Cobra has joined forces with the mad genius Dr. Daimon to spread a toxin so lethal it can destroy all the plants in the Amazon in just six weeks.
The meaning is clear: Without all that oxygen, every being on earth will smother!
All eyes are on you, Lightning - you're the expert at split-second tactical decisions. Which assault team should you choose: Airtight, Roadblock, Alpine, and Iceberg, to hit Daimon's fortress in the sheer Andes? Or Lady Jaye, Low-Light, Beach Head, and Wet Suit, to penetrate the Amazon and knock out the toxin fogging device? And what if you're too late??
Crack Cobra Snow Serpents and savage Cobra-trained Indians await you. You must strike fast, Lightning, as you FIND YOUR FATE.
