Missions have a beat ’em up style where players must defeat a massive amount of enemies to reach the final boss. Many characters from the Marvel Universe appear in Marvel Super Hero Squad Online in a traditional Super Hero Squad “super-deformed” style. 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. Gold points can be used to buy most heroes, while silver points allow a player to buy additional items for their Headquarters.
Points are separated into two compartments, gold and silver. If the character is unable to fly, that character can have a double jump or a high/long jump. Selected characters can fly by pressing on green circles on the ground. 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. As they play, the heroes increased not only their power in combat, but unlocked animated emotes for use in the social game world zones.
They were able to choose a hero from their Squad to play in a number of games and activities. Players could collect heroes to form their own Squad. 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.
