Here you can find a brief summary and overview over the development history of NS:CO. From the ideas that led to its inception, through its development and release as a total conversion all the way to the current standalone release.

Navy Fortress

1998 - 1999

The predecessor project to NS:CO built on the Quake 2 negine. Here the core of Team Mirage was founded with BenB joining the two Nerurkar brothers. The game was inspired by the the Navy Seals mod for Q2 and other semi-realistic games like Action Quake.

Quake 3 Mod Development

2000 - 2002

With Quake 3 released the team wanted to work on something bigger, and so Navy Seals: Covert Operations was born. A concerted development effort began with many other hobbyist joining Team Mirage. Alongside school development took much longer than expected.

Mod Release

March 9th 2002

The total conversion was highly anticipated. Even though the initial release was a little rocky, lots of players joined in and a stable and active community quickly formed.

Continued Development

2002 - 2005

Many more updates followed and the game was consistently improved and expanded. Since everyone involved was a hobbyist development was still slow until in 2005 the project was ended. The core team was planning to move to a different mod based on a more up to date engine.

Standalone Gold Effort


After the Quake 3 engine source code was released in 2005 under the GPL license, a standalone release of NS:CO was possible. In 2007 Democritus started an attempt to release a definitive "gold" edition with an overhauled UI. Unfortunately this effort never reached its goals.

Gold Revival


In a surge of nostalgia, Democritus put together another effort to release NS:CO gold. The progress in the other open source Quake 3 engine based projects since 2007 was helpful here and after a lot of cleanup a definitive version was made available.

Standalone Gold Release
