An underratted and unapreciated game.
Adding to the realism is how vehicles are actually dammaged, tanks especially. Say you fire an armor peircing round from your tank at an enemy vehicle. Say the shell hits something useless or something that wont cause much dammage. The enemy vehicle will rock from the impact but it won't take much dammage. Now say you hit an ammo bin, or the engien. KABOOM!!! Explosions look amasingly realistic.
Infantry, appropriately, can't do much to tanks, but arent helpless. A small collection of rockets, AT grenades, and mines can be used to take out enemy armor if need be.
All in all this was a great game that got no recognition. If the company could have marketed beter, I'm sure this game would be recognises as the premier WW2 RTS.
