Infinity Ward's twitter page (as well as FourZeroTwo's) has alerted us to a series of what seem to be beta invites from Infinity Ward going around for the next Call of Duty. These are fake, do not open them. The e-mails originate from COD5BETA@infinityward.com. If you get an e-mail from this address delete it.
Infinity Ward says:
"Heads Up - There's a fake Beta Invite going around from COD5BETA@infinityward.com. If you get one, just delete, don't open."
