SuperSecret, Inc. announced this morning that it has raised $10 million from Opus Capital to fund product development and distribution efforts in anticipation of a launch next month. The company’s primary game, also called SuperSecret, has been in beta mode for a few months. This is the second funding this week of a tween gaming venture. OMGPOP yesterday announced it had raised $5 million from a group of VC funds including Bessemer Ventures and Spark Capital. Though both ventures target tweens (kids 8 to 14), SuperSecret has a virtual-world twist — users create characters and interact with other users inside the SuperSecret world — while OMGPOP doesn’t.
