Harpoon © 1989 Three-Sixty Pacific, Inc.
The Harpoon software engine contained over 115,000 lines of code, with most written in the C programming language and the remainder in Assembly. The original program was 426K and supported (through separate graphics files) CGA, Tandy, and EGA video formats. After 30-months of development, and at the cost of over $300,000, the computer game was released on December 18, 1989 (Monday) for IBM PCs in the USA.
