Sentinels of Earth-Prime is a cooperative card game that recreates the pulse pounding action of superhero comics. This epic team up between Green Ronin Publishing and Greater Than Games uses the rules of the hit game Sentinels of the Multiverse and the setting and characters of the critically acclaimed Mutants & Masterminds Roleplaying Game. Play a hero of the Freedom League like Lady Liberty, Captain Thunder, or Johnny Rocket striving against the schemes of villains like Argo the Ultimate Android and Omega, Lord of the Terminus, in dynamic environments like Tartarus and Freedom City. Sentinels of Earth-Prime is a stand-alone game but everything is 100% compatible with previous Sentinels of the Multiverse releases and decks can be mixed and matched as you desire. The game includes 18 card decks (ten heroes, four villains, and four environments), as well as tokens, dividers, and a rulebook.
