Adventures in the Lost Lands is a tabletop miniature wargame based on the Two-Hour Wargames' Chain Reaction system. It provides rules for gaming with dinosaurs, mammalian mega-fauna, and other prehistoric creatures in a variety of eras and settings.

From the website:

Adventures in the Lost Lands introduces you to a world like no other, a world of giant creatures and prehistoric men where you can:

-Be a Pulp Era hero exploring lost lands and searching for valuable treasure
-Lead your tribe of primitive cavemen in a fight against other primitive tribes
-Be a modern-day big game hunter who travels to a prehistoric land that Time forgot
-Command a Victorian-era expedition bent on discovery and conquest
-Be a dinosaur (not only a dinosaur, but THE dinosaur), as you take on all others for supremacy
-Or maybe command a squad of WW 2 GIs hurled into a strange prehistoric world while on maneuvers in Louisiana (it's a long story....)

In Adventures in the Lost Lands, you can do all of this and more. We've included a number of linked scenarios forming a campaign that can be played solo, cooperatively with all players on the same side, or head-to-head against your friends. It's all up to you!

Adventures in the Lost Lands is a stand-alone game that can also be used with Larger Than Life and other Two-Hour Wargames rules.
