The Attack of the Artifacts bundle does not include any Pizza. It does include three Magnificent Artifact chests. These can be found from the House of Artifacts chest store (and only there) in the extreme right of the single player campaign map (near the level 7-8-9 AotA treasure hunts) or on the right edge of the multiplayer screen. The chest shop graphic should have a blue star with the number 3 over it before you open the chests. Hope this helps and Happy Hunting!
