TimeWarp
TimeWarp is a fan-made project based on the Star Control Universe and game dynamics. The developers were disappointed with Star Control 3 and want to create a "true sequel" to the epic Star Control II. The original TimeWarp project has spawned several forks.
TimeWarp
At the time of writing it has the melee portion of the game implemented, which contains an enormous selection of ships. The classics from all three Star Control games are coupled with a wealth of fan-made vessels. You can even fight in the planet lander!

Public Plot Initiative
The public plot initiative is an initiative for and by the public, which develops a plot set in the Star Control universe, using ideas and suggestions that are posted on the Timewarp forums.
TW-Light
TW-Light is a TimeWarp fork created by Yurand and Youbstrd! in 2004, and intends to produce a more clean and stable codebase. It also has a revised Melee mode, which features a more selective roster of ships. TW-Light is more actively developed than the original TimeWarp.

Legacies
Legacies is the first-person "story mode" component of TW-Light. Work on this story has halted due to lack of developers; the Legacies team is on the lookout for new writers and artists.
TWX
Another fork of TimeWarp, this project was created in 2003 after some dissent in the Timewarp team, by Tau, GeomanNL and UAF. Originally it aimed at creating an adventure in the Star Control Universe, but after some setbacks, the project aims at more modest goals which will be completed in turn - namely, (1) a playable mission set, (2) a simple real-time-strategy, and (3) an adventure. These goals accompany the completion of different critical parts of the code.
