Beta Paths

The Callisto Protocol - Beta Paths

Currently, Beta Paths, which were discussed during the game's pre-release, do not exist in the form of alternate routes. There are, however, optional explorable areas that often contain Data Bios, which add to the backstory.

The game is a fairly linear experience, and as it currently stands, it seems that there are no alternative story paths to take in the Callisto Protocol.

What are Beta Paths?

Missed Weapon Schematics Can Still Be Found

The Callisto Protocol - Skunk Gun Schematic

Weapon schematics are items found all throughout Black Iron and can be purchased at any Reforge. Should a player miss the initial location for each schematic, it will appear in a different area later on.
