Transarctica - ice cold train combat
This is everything I need from computer game - strategy, tactic combat and cool (literally) setting.
The world has come to an end, the sun is gone, the earth has turned into an ice desert. In an attempt to save the world from the Greenhouse effect, scientists detonated nuclear charges at both poles of the planet. By doing so, they created a vapour layer in the atmosphere that, instead of cooling the planet down, led to eternal winter. The nightmare of scientists and environmentalists has become a fact.
