Launch a missile to defend the mothership from incoming enemy ships. The longer you can keep it in play to destroy enemies the higher score you can build up! Detonating the missile will destroy all on-screen enemies but forces you to lose your multiplier. Try to keep each missile you launch going for as long as possible between detonations to get a great score!
Press the space bar to launch and detonate your missile. Use the left and right arrow keys to move.
