Doom 2016 (PC) Walkthrough Chapter 11 The Necropolis 100% complete

Doom 2016 is FPS game developed by Id Software and released by Bethesda Softworks in 2016. Being remake of classic Doom we play here as mysterious Doom Slayer, some kind of superhuman who fights demons from Hell invading human base on Mars. Game is based on classic Doom where we eliminating enemies in fast and brutal ways. My goal was to find all secrets in game and complete all possible challenges. I chose lower difficulty because on Ultra-Violence it could be hard to complete most challenges without dying.
