I'm not at home right now, but I'm almost certain I installed the downloader to E:/Games/ as I do with all such stuff.
The Great Wall map is good fun. The other two, while looking ok are a bit too armour dependent for my tastes. Tanks everywhere.
I really don't understand the 32 player thing either. The maps seem plenty big enough for more, so I don't get why they're limiting it.
Frustratingly considering the quality of all the other models in the game, the Eurofighter is absolute pish. It also has 1,000lb bombs mounted on the outboard wing plyons, with A-A missiles inboard. I know all that's only superficial, but it's also a bit stupid.
Six quid really is peanuts tho'. Consider what little else you could buy for similar money, and get it downloaded.
