I'll just steal the description from our Fan Projects page.
Time crisis is a tribute to the Wing Commander and Star Trek universe. It is an original fan project and is planned to be a simple yet addictive 2D Prince of Persia style game. However, the gameplay is aimed to be a lot more advanced and also involve team strategies. They are using the Mappy Map editor to create the maps and C++ to make the program.If you want to help, you can mail the project leader here.
