Yup, they should open up to more payment methods. Two of my clan mates don't have credit cards.
There is no retail and gifting is not possible. Bummer.

Yeah I thought they would at least have paypal. A lot of people simply wont be able to buy. Another Crytek slip up in the long list of slip ups.! Great maps BTW.

PS when voting for which new map to play on I only see the older maps pics. When voting is over the game begins boom im in the new maps, any ideas or manual install of the maps ?

Look for this "My document"-folder of Windows, where most games store their save games. Mine is translated to German, but yours should be named "My documents" or something like that.

In there is a "Crysis 2" folder and in there is a "dlc" folder.

Empty this one.

Place the dlcpack1.zip in there.

Start the game.

I have no 'Crysis 2' folder in My Documents :S i have looked in both folders 'My Games' and 'EA Games' and there is no folders on Crysis 2.

If you have Win 7, go: Start-Username-Saved games-Crysis 2

You place the zipfile in the / My Documents / User / Saved Games / Crysis 2 / dlc folder.... just put it in there and start the game. Yea it was a pain in the arse, the most goofey DLC I have ever seen, but it does work and the maps are really nice. Just make sure you can find the dlczip after you dl it. You can't get the file In The Game, you pay for it in the game, but you have to actually DL it from the gamesas site in the purchases screen. log in first.

C:\Users\Thor\Saved Games\Crysis2\dlc

in the local version of windows the folder is covered with the localized name of the directory for example "Gespeicherte Spiele" ...
ff*ck*ff Crytek learn to programm.
