MW3 is a pretty barebones action game featuring a sequence of disjointed mech arena battles that supposedly make up a campaign. There is no real plot or story, and the mission briefings are written in hilariously broken English.
The combat is more or less functional. It is pretty unwieldy to control your mech which can aim and move independently, and for this reason the most effective strategy seems to be to rely on the lousy AI to walk directly towards you (which it does when you are further than 100m away). Funny enough the best method of ensuring this is to promptly kill your "wingman".
All of this would be quite forgiveable from a two dollar game, except that the rate the game dispenses necessary upgrades is so remarkably glacial that it was clearly intended for you to buy the in game currency (which comes at an obscene premium and is dispensed in amounts designed to make you buy more than you want).
A despicable setup, altogether, from a lousy game. Avoid.
