Superheroes Galore! That's right, this is a superhero based online card game. Pick a team of heroes and battle against some seriously tough foes. Use cards based on your powers, environment, and effects, and let everything stack to make sure your foe never destroys the earth. The core of the game has 10 heroes, 4 villains and 4 different environments to play in. Each mix and match will yield a completely new experience in the game, and you never know what card your opponent will pull out next.
Sentinels of the Multiverse was based on the idea of various comic-book related games out there. The creators wanted to do something different than the normal one on one fight between a hero and villain, and thus came up with the idea of a mix and match type card game that allowed for far more variety than traditional hero-based video games would.
Expansions, activate! The game also has an expansion pack that released just a little bit after the initial game release, and added even more content to the game that gave players a whole new mix of matchups and battles. Multiple expansion packs have released since then, with the final one having been released in 2016. Card games online can be fun, but they can often become repetitive and predictable after a while. This one, however, will really give you a run for your money with the amount of different variations you can have on the hero-villain-environment combinations.
Multiplayer too? Yes, that's correct! The game can have up to 4 players that work together to beat their foe. Each one can control one or multiple cards, and can team up and strategize with their fellow heroes to figure out how to conquer their foe. As far as strategic card games go, this one is probably one of the best out there!
