Kali is an IPX network emulator for DOS and Windows, enabling legacy multiplayer games to work over a modern TCP/IP network such as the Internet. Later versions of the software also functioned as a server browser for games that natively supported TCP/IP. Versions were also created for OS2 and Mac, but neither version was well polished. Today, Kali's network is still operational but development has largely ceased. Kali also features an Internet Game Browser for TCP/IP native games, a buddy system, a chat system, and supports 400+ games including Doom 3, many of the Command & Conquer games, the Mechwarrior 2 series, Unreal Tournament 2004, Battlefield Vietnam, Counter-Strike: Condition Zero, and Master of Orion II. The Kali software is free to download, and once had a time-based cap for unregistered versions. For a one-time $20 fee, the time restriction was removed. However, as of January 2023, Kali.net offers the download and a registration code generator on the website, so registration is currently free. History The original MS-DOS version of Kali was created by Scott Coleman, Alex Markovich and Jay Cotton in the spring of 1995. It was the successor to a program called iDOOM (later Frag) that Cotton wrote so he could play id Software's DOS game DOOM over the Internet. After the release of Descent, Coleman, Markovich and Cotton wrote a new program to allow Descent, or any other game which supported LAN play using the IPX protocol, to be played over the Internet; this new program was named Kali. In the summer of 1995, Coleman went off to work for Interplay Productions, Markovich left the project and Cotton formed a new company, Kali Inc., to develop and market Kali. Cotton and his team developed the first Windows version (Kali95) and all subsequent versions. Initially Kali appealed only to hardcore computer tinkerers, due to the difficulty of getting TCP/IP running on MS-DOS. Kali95 took advantage of the greater network support of Windows 95, allowing Kali to achieve mainstream popularity. In the mid-1990s, it was an extremely popular way to play Command & Conquer, Descent, Warcraft II: Tides of Darkness, Duke Nukem 3D, and other games over the Internet, with more than 50,000 users worldwide by the end of 1996. The fact that only a small one-time fee was charged for the service, rather than a monthly subscription, also contributed to its popularity. This was largely possible due to Kali's
