Developers of co-operative climbing game Peak reportedly used false information in the game’s files to prevent dataminers revealing its final biome before release. The tactic mattered because the team wanted players to discover the update as intended, rather than having its main surprise exposed in advance.

The fabricated references included locations such as Heaven, Hell and Wisconsin, designed to mislead anyone searching the game data for clues. The real update added the Mesa biome, a desert-themed area that forms part of Peak’s post-launch content.
