Battle for the Purple Islands is the newest release from the Dark Lord, +Venger Satanis. It's written for Venger's games (like Crimson Dragon Slayer and Alpha Blue) and can be used with just about any D&D-ish system with minimal effort. I've read through it a few times and it's a blast.
The adventure centers around a courier needing to deliver a hologram message to a hermit that lives in a mountain located on the Purple Islands. Depending on the system your playing the character could be the couriers (if playing Alpha Blue) or they could be captives of cannibals alongside the courier. The players need to escape the cannibals, avoid intelligent ape patrols, make it up the mountain, and deliver the message to.... H.P. MF'ing Lovecraft. Oh, but that's not all kiddies. In addition, players must escort the master of the macabre to a museum with his work, avoid a sinister snake man, and stop purple cultists from nuking the island and turning everyone in to Lovecraftian monstrosities!
Pros: The adventure is a gonzo hex crawl and the Purple Islands are an unforgettable setting. You like something, the Purple Islands has it or can with little-to-no explanation. Grindhouse-style cannibal tribes? Check. Talking apes with machine guns? Check. Lovecraftian monsters out the wazoo? Triple check. Killer juggalos? They were mentioned in the first excursion to the Purple Islands, not this one, but still... check! Though the setting is on a fantasy world, reality's boundaries are thin and you can add whatever the Hell you want.
Do you like references and homages in your games? Venger sure does. There are some pretty obvious ones like A New Hope and Cannibal Holocaust, but there are some you might glance over, like Ghostbusters.
Finally, like all of Venger's works, this one is full of random tables to keep things fresh and interesting, including a Land of the Lost roll as you go hexcrawl chart with 100 entries.
Cons: You're going to really want The Islands of Purple-Haunted Putrescence if you're running this. Now I don't think that's a bad thing. Quite to the contrary I love that book, just saying if you have this one, you're probably going to need that one.
Final Verdict: If you've ever wanted to do a Lovecraftian version of "Vincent and the Doctor" mixed with a little Planet of the Apes and a bloody dollop of Cannibal Holocaust. this is the adventure you've been waiting for.
If not, what's wrong with you?
