Sunstorm Interactive was the video game development company responsible for Cryptic Passage, an expansion pack for Blood. It was well known for creating the Skunny the Squirrel series and Deer Hunter series, spawning the hunting game genre, but enjoyed its most success from value-priced expansion packs for Build engine games, including various expansion packs for Duke Nukem 3D. They also later built Duke Nukem: Manhattan Project, a three dimensional platform game released to moderate success. In 2003, after being unable to regain the same level of profitability, Sunstorm shut down due to financial difficulties; with Gabriel Entertainment being a quasi-successor. Recently the company seems to have been reborn and entered the mobile gaming market and technical consulting.
