THQ has sent along another new video promoting the upcoming Company of Heroes 2, this time a dev diary style clip titled "Preparing for War" that features commentary from the game's developers at Relic Entertainment.

The video offers a closer look at several key features, such as TrueSight the line-of-sight system that controls the game's dynamic fog of war, and Cold Tech, a collection of environment mechanics that includes deep snow, frozen waterways, and extreme cold that affect different units in different ways.

We also get a good look a the new infantry vaulting ability, which means no more walking the long way around fences and sandbags, and a couple of quick peeks at the game's UI HUD, which we've screen-grabbed below for closer inspection.

Watch the video embedded below, or here in our HD video library.

Company of Heroes 2 is due on PC in March 2013.
