Battlefield?

Dream: There was this sort of a shallow canyon in winter. Everything was covered with snow. The "canyon" was not very steep, it was only about 8-10 metres deep and you might succeed jumping over it. There was a small thin bridge built over it, made of dark brown wood.

Some man wearing some 19th century war uniform lowered himself down the hill to the bottom of the canyon. I saw a weapon selector hud show up, just like in Max Payne. He chose to use Ingrams but he never took them out. He was clearly protecting this side of the canyon from possible attackers.

After a while some enemy troops started rushing from the other side, deep from inside a wintery forest. He beat them all.

Analysis: Games, games, games I've never even played and never will!
