Fans of running up buildings and mutilating crowds in spectacular fashion weep.
Today it was announced that Radical Entertainment, creators of the Prototype franchise, have been closed down. According to Activision (their parent company):
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. 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.
