This RTS War game offers challenge for anyone who's up for it. You take a Command of Axis Forces or Allies Forces or then Russia.
I didn't understand everything in this game to be honest. I played it through as Axis forces. What higher rank your commander is that more units he gets to command. Each of these units can be upgraded to different types. Scout cars, panzers etc and playing through some missions you get a special unit you can upgrade. You can get a Tiger Upgrade for one of your tanks when you do one mission and if you do it as many times as you have tanks you get each of your tanks as a tiger etc. The best strategy (meaning the laziest strategy) is to bomb every town and every strategic location with artillery till there's nothing alive...I've always done that since I'm a lazy tea sipper who wants his armored units to survive xD
