Mark 4 Wenja Achievement / Trophy | Far Cry Primal

Mark 4 Wenja is an achievement in Far Cry Primal. You’ll unlock it by visiting a secret cave in the game, where there is an easter egg referring to one of the older Far Cry games. This guide will show you how to unlock Mark 4 Wenja trophy and where to find the Blood Dragon cave.

The cave is located in the north-eastern part of the map. Once you’re in the snowy area, get to the river and follow it upstream. You’ll find a cave at the headwater source of the river. Some rock climbing will be required, but once you’re up on the plateau, the entrance will be obvious. Follow the corridors until the cave opens up. You’ll see a dinosaur skeleton surrounded by glowing, purple eggs. This is when the achievement should register.
