Terrain and time of day are all taken into consideration when you make ready for battle. Slogging through heavy snow reduces speed and mobility, while the heat from your weapons is dissipated quicker. Running in open desert gives the freedom of speed and view while at the same time you have to constantly check your heat sinks, otherwise you risk a system shutdown right in the middle of a firefight. That isn't a good idea because you become a 60-ton sitting duck. Your family was murdered in cold blood, and you alone survived.
Vengeance is sweet, like the siren song for massed combat.
You are at the vanguard for a war, and your decisions could impact the rest of the galaxy for centuries to come. Under manned and under gunned, you must fight through unimaginable odds to win. Using guerrilla tactics, and salvaging supplies and 'mechs you lead a determined group of rebels to fight off the attackers of your home world. Nothing is sweeter than victory. MW4 can challenge even the most seasoned of 'mech pilots yet at the same time is very easy and fun to learn.
