Activision is crowdsourcing its next personalization pack for Call of Duty: Black Ops 2. Starting on Thursday, May 23, fans will be asked to vote for one of four new packs, each with their own custom weapon camo skin, three reticles and a calling card icon.

One of Swords has preview images of all four personalization options. Voting ends May 28; the winning pack will go on sale the following day, May 29.

Personalizations are optional "micro items" you can purchase in Black Ops 2 on Xbox 360. While Activision has said the functionality will come to other platforms, it has yet to announce any additional details.
