Zombie PSA!

Don't know why you would be installing Halo 3 to your Hard drive when Left 4 Dead is out but DON'T

Don't copy Halo 3 to your hard drive!

Yes, apparently Halo 3 is broken when it comes to copying to your Hard Drive.

Basically, the game was programmed to copy map files from the disc to the HDD to speed up load times. If you install the game to the HDD, it copies the files from your HDD to...another part of your HDD, which is a lot slower than a disc-to-HDD transfer.

No idea if they will fix it or what other games are also flawed in this way. Stay tuned.
