Battlefield 2: Armored Fury is a good way to add a few weeks of life back into Battlefield 2.
Anyway, unlike Euro Force, Armored Fury does not add any new armies or weapons, but it does add new cars, helicopters and airplanes. Driving around American harvest country in a a civillian car is a total blast. Trust me :).
The maps are good, not as good as the original Battlefield 2, but they add new life, which was the point in this booster pack. The maps range from an Alascan oil pipeline, to a highway, to Dutch farm country. Unlike Battlefield 2, the maps in Armored Fury are about tanks, and tank battles.
Midnight Sun is a map set in Alaska, and is a good map. US and Chinese forces are entrentched on two sides of a river, and must try to capture the outposts on the other side, in the double assault. Operation Road Rage is a map that takes place along a highway in America. The US start out in a small suburb\village, and the MEC spawn in a mall. Both sides need to take several CP's, one of which is a highway, and several typical American features.
Operation Harvest is the gem of Armored Fury. It takes place in Dutch farm country, and takes place along open fields, with several open areas for tank battles, and many more for that annoying anti-tank to hide :P. The only bad thing, is that the massive amounts of tanks will own the lone infantry.
The Battlefield 2 engine is starting to show it's limits when Armored Fury came around. Sure, the enviroments look amazing, but as Gamespot said in their review, the lack of interaction is really something that gets on your nerve. Thankfully, the upcoming Battlefield: Bad Company will give us 96% interaction with enviroments. No word on a PC version yet, though...
To conclude, Armored Fury is a worthy addon to Battllefield 2, but just don't expect to get as much out of it as you did the original, or even Special Forces. Better then Euro Force, because of the maps.
