Petroglyph announces September 12 as the launch date for Rise of Immortals, their free-to-play MOBA game. "The Rise of Immortals development team is a passionate group of battle arena fans, and we are all eagerly awaiting the game’s official launch on September 12," said Steve Wetherill, executive producer of Rise of Immortals for Petroglyph. "Throughout the development process, we’ve worked internally and with our fans to create a MOBA game that adds all kinds of exciting new features to the genre, and we can’t wait to open it up to the world." Here's more:

Rise of Immortals, an online PC game that expands on the hit MOBA genre with new, innovative features, is currently in the final phases of an open beta test. Players still have a chance to be part of the test and receive the exclusive gifts that testers will receive: 1,000 Petroglyph Coins at commercial launch (worth over $10), and an exclusive Immortal skin. The Immortal skin, a dazzling gold version of the robot-suited Psychozen, named “The King of Bling,” will be available exclusively for open beta testers to enjoy both during the beta test, and as a complementary add-on to their account at launch.

Anyone interested in participating in the open beta test can register at http://www.riseofimmortals.com, and will be immediately invited to download the game and start playing.
