Ghostmaster.net (thanks Frans) reports
the closure of Sick Puppies: "We're sad to discover that Sick Puppies, the
developers of the PC version of Ghost Master, have closed their doors. This is
because the games publishers Empire Interactive didn't feel it had performed as
well as it could have done."
Ghost Master is a great game, but it was just too different from the usual type of game. They should have set it in World War II, and it would have been a hit.
