How to hide the battery meter in Crysis

Crysis Warhead isn't a multiplayer component. It's a fully single-player game in fact, telling the story from the viewpoint of Psycho, with in my humble opinion better gameplay than the original.

You're talking about Crysis Wars, which is a separate game bundled with Warhead, as its multiplayer component. This is in contrast with Crysis where the multiplayer was integrated.

I would say getting Warhead is definitely worth it to add to the story and have a multiplayer game.

Someone else seems to be in this position, judging from this post on the Tech Support Forum.

The answers from the site moderators indicate that you can't legally download these.

If you do not have the English pak on the CD like Koala said we wont be able to help you as it will infringe on EA's copyright agreement.

and

Yes, there are different DVD's of the game with different contents (language pack), each DVD has a license agreement. So If you have a DVD from Australia and send it to Turkey but the Australian version has no Turkish language pack you are unable to alter the game due to the license agreement as it will be altering the original copy which resides on the DVD.
