Men of War: Assault Squad features a completely new cooperative skirmish game mode with access to five different nations (Russia, Germany, USA, Commonwealth and, for the first time ever in the Men of War series, Japan) as well as increased realism and accessibility.
It's a great game, there's lot of mods for it and the controls and army control is superb. The direct control feature for armies is just brilliant and we need more RTS games which have this feature.
