Marvel Super Hero Squad Online was a free-to-play, children-friendly massively multiplayer online game for PC by Gazillion Entertainment, based on the Marvel Super Hero Squad franchise. Players could collect heroes to form their own Squad. They were able to choose a hero from their Squad to play in a number of games and activities. As they play, the heroes increased not only their power in combat, but unlocked animated emotes for use in the social game world zones.
Marvel Super Hero Squad Online has alternate controls, in which with one click the player can move from one place to another, or using the arrow keys or the traditional W, A, S, D keys on a keyboard. Selected characters can fly by pressing on green circles on the ground. If the character is unable to fly, that character can have a double jump or a high/long jump. Points are separated into two compartments, gold and silver. Gold points can be used to buy most heroes, while silver points allow a player to buy additional items for their Headquarters. A prize wheel, somewhat similar to prize wheel in Webkinz, serves as a way for players to more easily unlock free gold or silver and other items. Many characters from the Marvel Universe appear in Marvel Super Hero Squad Online in a traditional Super Hero Squad “super-deformed” style.
Missions have a beat ’em up style where players must defeat a massive amount of enemies to reach the final boss.
Game World Areas are separated as zones. Zones include the Daily Bugle, Baxter Building, and Asgard with all taking a small portion of Spider-Man’s, the Fantastic Four’s, and Thor’s home locations. Additionally, Villainville has been made available for players to visit, as a zone.
Recently as of April 10, 2012, Asgard has been updated with major changes; the Bifrost bridge has been broken, and the city has been attacked and conquered by Loki. Also, Loki’s design changes from the original SHS version to the one from the Marvel Cinematic Universe (presumably to foreshadow the events of the Avengers film). The entrance to the palace has also been replaced with a table holding the Tesseract. By clicking it, players will be able to play a mission with the Movie Loki as the boss and upon victory, receive a ‘goodie’ Cosmic Cube.
A collectible card game was made available to play. An arcade has been developed where players can play as Deadpool, She-Hulk, Black Panther, Daredevil, Captain America, Thor, Doctor Strange and Jean Grey in selected mini-games. Two characters such as Deadpool and She-Hulk are featured in each mini-game. A challenge system was released that allows players to complete several challenges such as greeting other players, buying new heroes, beating missions or card game quests. Each challenge completed awards the player tickets, silver coins, gold coins and new heroes.
