I remember this old game I used to play when I was a bit younger.
I don't exactly remember the name of it but I remember one mission from it distinctly.
You led soldiers through a cold winter snow and had to move between the fires set up on the game map, and if you didn't the soldiers would slowly die. Eventually you reached I think some kind of settlement, and then that's all I remember. I think it was an RTS game but don't quote me on that.
