Deep Snow
From WikiRaider
Deep Snow can be found in the Siberian Locations of Rise of the Tomb Raider. Lara can only move slowly when she walks through Deep Snow.
The first time she encounters Deep Snow is right at the beginning of the game when she climbs the Mountain Peak together with Jonah. Later, when she has to flee Mishka, the Bear that lives in a Cave in the Siberian Wilderness, she can get stuck in Deep Snow on the path and thus be slowed down enough for the bear to get her.
When travelling through Deep Snow Lara leaves behind deep tracks. Patches of deep snow can be jumped over, but as soon as Lara stands in Deep Snow jumping out of it is no longer possible.
