Rise of the Tomb Raider - "Red smoke on the ice" boss fight (SURVIVOR - STEALTH/MELEE KILLS ONLY)

Very fist attempt. Incredibly easy even at survivor difficulty. You could say I abused the broken stealth kill system of the game... and you're RIGHT. I realized it was actually doable during the "Never Underwater" video. I played this section using the expeditions mode "Replay level - elite" on "survival" difficulty. Think of it as some kind of a new game+ : all skills and weapons obtained during the campaign, you can use 'em to play past chapters
