Easter eggs on the Revolver Peacemaker (Battlefield 1)

Prompt, to successfully complete the last stage and get the revolver, you need to have all 5 tokens from the previous Easter eggs? I have only tokens of a Sign, the angel and the Belly of the Beast, well, skin Climbing M1917, and tokens, the Beginning and the Conflict there.
When you try going through the last stage on level 10 of the maze appears eerie sound and it's killing me vanshotom, even at 100% HP. Help
