UNLOCKS: If following the guide, upon collecting the secret balls (canon) in Mission 3, Siberiade, just before the Ingenious puzzle.
DIFFICULTY: Any
CO-OP: Unlocks, all players (all players must individually collect all secrets)
METHOD: See Methos' excellent guide below (all credit to them). Collectibles are not missable, thanks to chapter selection. You can quit the mission after getting the secret you need and it will count. Secrets include the classic levels. Print media, Dmitry's logs, and Brand's logs are not included.
NOTE: Be sure to hang on to at least half of your C4 so you have it available for accessing the classic levels. Some levels require more than one C4.

Mission 2, The Song of the Stormbringer 11 secrets
Mission 3, Siberiade 27 secrets
Mission 4, Roadside Picnic 16 secrets

WHILE YOU'RE THERE: As they are not included, I like to have videos up for the audio logs and print media in tandem.
