Gazillion launched “Marvel Heroes 2015” for the PC on Wednesday, and the beta is opening for Mac players.

“'Marvel Heroes 2015’ is a new launch for the ‘Marvel Heroes’ brand coinciding with a one-year anniversary milestone on June 4, and it highlights all the new game content added since launch,” publisher Gazillion said in a press release.

"Marvel Heroes 2015 nicely represents everything we have accomplished and intend to accomplish with one name," Gazillion CEO David Brevik said. "We've come a very long way since our original launch a year ago, and the now imminent release of ‘Marvel Heroes 2015’ alongside our massive anniversary celebrations marks the beginning of something even better. Whether it's defending the X-Mansion or recruiting your favorite superhero as a Team-Up, we're excited to continue delivering on our community's expectations."

New features in the game include an Omega System that allows in-depth character customization and progression, daily shared missions, an epic end-game that allows up to 10 players to participate, login rewards and achievements.
