I barely remember the game, however i remember that there was an option for 2 player mode where one played with the keyboard and the other with the mouse. I also remember that the game moved from the top to bottom, im not sure of there were branching paths to pick in the 3d environment. The game was played top down and i remember one of the bosses (or the final boss?) Being a giant spaceship. That is all, thanks in advance!
