During a Far Cry 4 panel at this year's San Diego Comic-Con event, the developers announced an interesting contest: one person will get the chance to play Far Cry on Mount Everest.
The winner will use a specialized (but unspecified) piece of gaming hardware that both allows for playing on the go while also standing up to the harsh weather conditions of the icy mountains. [Note that a game has made the trek up Everest before; it was a DS, as detailed on this NeoGaf thread from 2005]
Ubisoft is looking for hardcore Far Cry fans, but the rules are straightforward: Upload a YouTube video explaining why you're the most qualified for the trek, and include "Far Cry 4 Quest For Everest" in the title.
Rules and restrictions for the contest can be found on the Ubisoft Quest for Everest site.
