Marvel has revealed more details on this summer's X-Men event, Extermination. Starting in May, key X-Men titles will include post-credits scenes that jump 20 years into Marvel's future where mutants are on the verge of extinction.

An infographic features the five titles that will give readers a glimpse of the X-Men's dark future, with a story written by Ed Brisson and illustrated by Oscar Bazaldua. This will all lead to Extermination #1 in August, from Brisson and artist Pepe Larraz.

The reading order for the Extermination preludes begins with X-Men Gold #27 (on sale now), X-Men Blue #27 (on sale now), X-Men Red #5 (on sale May 6), Astonishing X-Men #13 (on sale July 4) and Cable #159 (on sale July 18).

Text and art included in the infographic focuses on the original, time-displaced X-Men, who may not all survive the summer event. Along with headshots for Cyclops, Iceman, Jean Grey, Beast and Angel crossed out with a large X, the text reads, "Witness the final days of the original X-Men! Twenty years into the future, mutantkind is on the verge of extinction and we promise you, the X-Men will not survive! But how will this nightmare come to pass? And is it too late to prevent it? Find out in these issues, as we count down to 'Extermination'!"
