According to this post over at Blue's News, Rebellion has acquired The Bitmap Brothers. Here's a snippet from the full announcement:
Described as “Gaming’s first rockstars,” The Bitmap Brothers were responsible for what many regard as some of the stand-out games of the late 80s and early 90s, including titles such as Xenon, Z: Steel Soldiers, Speedball and Chaos Engine. Rebellion plans to bring classic The Bitmap Brothers games to new platforms, and going forward to create new titles based on its beloved licenses.
