As part of a cross-promotion deal, Sony is throwing in a perk for those that purchase Guerrilla Games’ gritty shooter Killzone 3 in the form of early access to the SOCOM 4 multiplayer beta. A PSN code that grants entry is included with all North American copies of KZ3. Participating retailers include GameStop, Best Buy, and Amazon.
