From Sentinel Comics Wiki
First discovered on the side of the Vengeance box
Sentinels of the Multiverse: Wrath of the Cosmos Takes the battle for the Multiverse into Space! Introducing two cosmic heroes, four dangerous villains, and two out of this world environments, the Multiverse will never be the same! Stand and fight for your planet!
Wrath of the Cosmos was the first expansion not to be involved with a Kickstarter on its own, officially. Although Vengeance never received its own kickstarter, it was still part of the Shattered Timelines reward structure. Wrath of the Cosmos instead had a pre-order event hosted on the Greater than Games website, with stretch rewards set for numbers of preorders sold. These included the Prime Wardens Promo cards, Omnitron IV environment, and the Wager-Master mini Villain deck.
