Apogee Software announces the release of the source code for Blake Stone: Planet Strike, the sequel to Blake Stone: Aliens of Gold, saying this helps celebrate the recent Apogee Throwback Pack release on Steam. They state they are releasing "what's left of" the code after discovering it after believing it lost. Both Blake Stone games were based on id Software's Wolfenstein 3D, and the source code for that is available for free on id-Software's GitHub archive. The download can be found on this page, and here's word:

After nearly 20 years, Apogee Software has unearthed the source code (or what’s left of it) for their classic FPS, Blake Stone: Planet Strike. This code (long thought lost) is being made available freely to the public as of today.

With the release of The Apogee Throwback Pack on Steam, interest in Blake Stone is at an all time high, and Apogee hopes that with the release of this code, fans will be able to bring Blake back in a whole new way.

“When we were selecting games for the Throwback Pack and decided to put both Blake Stone games in, I knew we had a golden opportunity to finally release the source code that Blake fans have been wanting for all these years. And when I contacted Mike Maynard, he agreed that it was definitely about time. Nice to know that those old 3.5″ floppies retain data for so long!” Terry Nagy, Apogee Software
