Pinnacle is an adventure scenario intended for player characters of levels 4-5 who join a tournament to climb a mountain called the Pinnacle, which is supposedly unclimbable but is actually hollow and holds an ancient secret inside.

[2] Pinnacle was written by Dan Greenberg, with a cover by Stephen Venters, and was published by Mayfair Games in 1986 as a 32-page book.

[2] He commented that "Pinnacle has an interesting cover, with three practically-naked people attempting to die of frostbite up a mountain.

"[2] Davis concluded his review by saying, "The climb itself takes up nearly a third of the 32 pages, and is entertaining as well as challenging.

The whole adventure will appeal to a group who prefer investigation and role-playing to simple dungeon bashes, and with a GM who is good at colourful NPCs, it could be a real delight.
