The Mac open beta for Marvel Heroes started yesterday, welcoming a new community of wanna-be superheroes into the fold.
The open beta includes all of the content that PC players get, including the recent Battle of Muspelheim raid. Gazillion is selling two special packages to go with the beta that include heroes and costumes. The packs are available for purchase by both PC and Mac players.
Currently, Marvel Heroes is celebrating its first anniversary with a month-long in-game celebration.
