While Order of War is remarkably easy to play, its two campaigns, each nine missions in length, can be difficult. Whether your mission is to ambush a convoy with paratroopers, destroy a massive German railway gun, or hold out against overwhelming numbers of Russians, you'll be put to the test. While most missions involve seizing all control points from the enemy, there are enough special objectives and other variations to keep the missions interesting. As you progress through each campaign, you earn experience points that you can spend toward persistent bonuses, like better tank armor or firing range. In one campaign, you lead the Americans on yet another romp through occupied France, in which preventing a German breakout from the Falaise Pocket and storming the fortifications of the West Wall are the most memorable missions. While the American missions are challenging enough to counteract any feelings of deja vu, the German campaign is more fun, thanks to awesome units, such as the King Tiger tank and the railway gun, and a two-front war, featuring epic battles against the Soviets. Unfortunately, this otherwise outstanding campaign is marred by two bugs: the mission where you defend the West Wall against the Americans often crashes to desktop, and in another mission, the victory trigger rarely fires properly. One disappointing omission from Order of War's single-player game is a Soviet campaign, instead the Soviets are represented both in multiplayer and as adversaries in the German campaign.
If you are going to attack Tigers with Shermans, be sure to hit them from behind and bring a lot of friends.
Multiplayer in Order of War doesn't break any new ground, but it's great for a quick blitzkrieg on your lunch break. MP is limited to six maps, each with two- and four-player variants, and there is only one game type, in which you must capture all the control points to win. However, the maps are well designed, with diverse terrain and natural choke points, so you do get quality if not quantity. Matches tend to be fast paced, with a one-vs.-one matchup typically resolved in under 30 minutes, partially owing to the fact that turtling is not an option, since you can't build any sort of static defenses or hide any weaknesses under a fog of war.
Overall, Order of War is a fun game that's far more engrossing than the sum of its simple parts suggests. Although it doesn't show any ambition to innovate the WWII RTS genre, Order of War roundly succeeds in delivering all the thrills, drama, and grandeur you'd expect. While some players will sorely miss details like battlefield scavenging and squad micromanagement, most will be having too much fun to care. So, if you are itching for an epic tank battle or just need a simple RTS game to bait your friends into the genre, Order of War is worth your attention.
