It’s time to tackle the toughest summit you’ve ever faced. On this epic ascent, keep your eyes peeled for beautiful prayer flags and looming pillars of ice. This mountain is as beautiful as it is dangerous. Don’t let it win. Unsurmountable: Big Climb includes 6 new cards, increases the size of the mountain to a whopping 15 cards, and also includes two new features: prayer flags and seracs. These are powerful factors in any climb that uses the optional difficulty rules. And for all the serious mountaineers out there, this expansion can be combined with Unsurmountable: Dual Peaks: if you can complete a 15-card mega-mountain with 2 peaks, you’ll be on top of the world.
