The first House to a certain amount of kills wins. The last House with a base standing wins. All other House bases must be destroyed. The first House to obtain a certain amount of ore wins the game. Teamwork is essential in all of these missions.
Credits are basically points.
Instead, a credits system has been installed. If you damage or kill any opposing House's pilot, you are awarded credits. Your total amount of earned credits determines what your rank in Silent Death will be. The credits that you earn in each game are cumulative. When you earn enough credits, you can upgrade your ship in a number of categories.
