Activision has shut down Radical Entertainment - the studio well known for creating the Prototype games. Activision has sent following explanation to Kotaku.

"Although we made a substantial investment in the Prototype IP, it did not find a broad commercial audience. Radical is a very talented team of developers, however, we have explored various options for the studio, including a potential sale of the business, and have made a difficult conclusion through the consultation process that the only remaining option is a significant reduction in staff."
According to Activision, "As such, some employees will remain working for Radical Entertainment supporting other existing Activision Publishing projects, but the studio will cease development of its own games going forward."

The developers have meanwhile posted on their official facebook page that inspite of the considerable reduction of staff from the studio, the PC version of Prototype 2 is still on the way and currently planned for release on  24 July.
