Danish developer Interceptor has bought 3D Realms, according to this Eurogamer report. Initially there was some confusion because the company said it bought Apogee Software LTD. The new Apogee - a separate company doing business under the name Apogee Software LLC - denied the report. This caused Interceptor CEO Frederik Schreiber to later clarify on Twitter.
The purchase of 3DRealms is happening in the midst of a new lawsuit filed by Gearbox Software, who claims that Interceptor's new game 'Duke Nukem: Mass Destruction' is violating its copyright. It bought the Duke Nukem brand when it purchased Duke Nukem Forever from 3DRealms...
