Marvel and Playdom’s popular Facebook game Marvel Avengers Alliance has been chugging along since early 2012, drafting new SHIELD recruits, teaming them with various Marvel characters and sending them on the hunt for SHIELD points and silver as they fight through the ranks of Marvel’s baddest villains.
In addition to the regular game, players are also treated to special operations every so often, which are sometimes based on storylines from the comics — like the recent one that drew from Dark Reign. Each special operation is typically limited to about three weeks, and if you complete all the mission objectives during that time, you unlock a new playable character — past missions have allowed you to unlock Emma Frost, Magik, Hank Pym, Vision and, most recently, Ares, among others. Occasionally they’ll also have you collect lockboxes that, through a process that’s probably long and boring to anyone who doesn’t play the game (and can be extremely frustrating for those of us who do), lets you gain a second character for your rather large team of Avengers. So far those characters have all been characters who have been both heroes and villains during their career — Magneto, Juggernaut and Elektra, for example.
