Trepidation is a Games & Entertainment::Action software developed by N5 Networks. After our trial and test, the software was found to be official, secure and free. Here is the official description for Trepidation: Trepidation is an open source first person shooter based on the IOQuake3 engine. Trepidation was a project originally conceived on April 9, 2006 with the intent to build a free first person shooter with a sci-fi theme. The idea was initially developed by members of the Star Trek Elite Force gaming community. The project disbanded before the game was complete sometime in 2008, but is currently back in development. We aim to have a game that runs well even on older machines that is fast paced and fun to play. you can download Trepidation 0.0.20 free now.
