Osseus – All 12 Secrets & Collectibles + 253 Platinum | DOOM Revelations 100% Guide

All 12 Secrets, Collectibles and Platinum locations in Osseus, Chapter 4 of DOOM: The Dark Ages – Revelations. This guide covers the all Osseus 12 Secret Areas, every major collectible, Relic pieces, Codex entries, easy-to-miss Platinum and Leader Essence Shards. Some of the Platinum pickups are extremely easy to miss, so I also included them alongside the secrets and collectibles instead of focusing only on the 12 Secret Areas.
