Marvel’s new Infinity Countdown checklist will help retailers and fans keep track of the comics that lead up to the upcoming limited series. The checklist is available as a download for fans, and retailers can find in on the Diamond retailer page.

The checklist guides readers to key Marvel issues that lead into the events of Infinity Countdown, from the rediscovery of the Infinity Stones in All-New Guardians of the Galaxy, the subsequent hunt for them, the revelation of their locations, and the reappearance of Adam Warlock.

Infinity Countdown Prime #1, by Gerry Duggan and artist Mike Deodato, will be in stores on February 21. Infinity Countdown #1 (of five) by Duggan and artist Aaron Kuder will be in stores on March 7 (see “Countdown to 'Infinity'”).

Marvel has several Infinity Stone collections and new material planned for early 2018 (see “'Infinity War' Publishing Build-Up”). The Marvel Cinematic Universe will also be hunting for the Infinity Stones when Marvel’s Avengers: Infinity War debuts on May 4 (see “First 'Avengers: Infinity War' Trailer”).
