Co-op action game PEAK receives final update with two biomes and a new secret

Co-op indie hit PEAK has received its final major content update. The developers have added two new biomes, another dangerous monster, item sets, and a mysterious secret that the gaming community is already working to solve.

The main additions in this patch are two zones with unique environments:

• “Gloom”: a frightening location shrouded in purple mist, featuring strange vegetation and complex mazes of barriers;
• “The Citadel”: a massive and dangerous zone filled with intricate mechanisms and deadly traps.

In addition to the biomes, the arsenal of available gear has been expanded with new items that players can take with them on their runs. The secret added by the developers will serve as the final puzzle for fans of the project.

This update marks the end of active content support for the game. You can purchase PEAK on its official Steam page, where a temporary discount is available in honor of the final patch release.

The Final Ascent is Out Now.

This PEAK update comes with two new biome variants: GLOOM and THE CITADEL!

We've also added some new items, bug fixes and a secret for only the most determined scouts…
