Next week Square Enix ships Order of War to stores and online. The first true Western developed game from this Japanese based publisher is a WWIi RTS game from developer Wargaming.net. However, the folks at Valve's Steam are giving people who pre-order Order of war from them some exclusive in-game units.

The units are off-map types, one for each of the two single player campaigns in the game. For the US campaign you get to use the powerful M115 203 mm howitzer while the nasty Nazis get to have their 17 cm Kanone 18 in Mörserlafette weapon. The game must be pre-ordered before Order of War is released on September 22 to get the extra units.
