However, the pick-up icon still remains in the game's data and has a string mentioned in the text files.

XM25: The XM25 from Call of Duty: Modern Warfare 3 has an unused Create-a-Class icon and a text string to buy it in Zombies, and judging by the different design compared to the used Create-a-Class icons, it was cut early on.
However, most of those weapons were still mentioned in the text files for Zombies (most likely leftovers from Black Ops).

The Mob of the Dead story concerns four prohibition-era mobsters who are serving time in Alcatraz Prison. They are Ray Liotta (Goodfellas), Michael Madsen (Reservoir Dogs), Joe Pantoliano (Cypher in The Matrix) and Chazz Palminteri (A Bronx Tale, Bullets Over Broadway, and the main cop in The Usual Suspects). The "top Hollywood talent" - the actors - featured in the Alcatraz Zombies map, Mob of the Dead, have been named.
