The face of war has really changed here in this game.
It's set in 1964, the 50th year of World War I, so it's set in an alternate history where two factions fight each other for one thing: peace. But who's gonna win? The Russo-Mongolian Empire, or the United States of Western Europe? Basically you'll find out, but once you hit near the end, you find out that another faction has joined the war, and is apparently using continued profits for themselves that has to do with the war but will be jeopardized by peace. You'll find out later when you hit the final level.
The game has siege tactics of WWI (trench warfare, mustard gas) with weapons of WWII (mortars, tanks) and has been mixed together with some modern warfare technology (unmanned robot-turrets, helicopters, spy satellites, wireless communications, etc.). If this occured in real life, all of these would end up with a few dire results.
Now onto the story. World War I has begun in August 1914, but instead of ending in November 1918, it continued on and this time, you aren't fighting against Germans, instead you fight against Russians, in March 1964. Iron Storm has its own selection of fictional weaponry, such as the assault rifle, flak cannon, and even the Consortium gun (guess what "Consortium" belongs to) which appears to be some sort of submachine gun with a fast rate of fire and has a 50-round clip. And each weapon has their own name (machine pistol's named "Heckler & Koch MP6," and assault rifle's named "MG-36a," even though none of these bear relationship to the real-life counterparts).
There are some bugs and problems with the game. One particular bug is a sound problem with sounds like like either loud static or an audio anomaly. Another is more annoying. Yet the game's difficulty is really hard. You can't take enough damage before dying, and medkits are rare. You can't recharge your health, so you'll have to break red crates containing them, or in rare cases, you'll find them hanging on racks or laying on the ground. Enemies also will charge at you, so make sure you snipe unsuspicious enemies with the sniper rifle and mow down charging enemies with your assault rifle or machine pistol if you have any of them. There are also dogs which either blow up or bite you. They bite hard, so kill them quickly. Also keep an eye out for the enemy turrets, they chew through your health quickly so destroy them with grenades or rockets.
That said, Iron Storm is a good game. The developers should work on the difficulty a bit more, because on easy mode I get pinned down by a sniper on the church tower and I can't see him because of the fog! Well, if you're a pro, at least get through this in at least 10 hours or less.
