Demons of OsirisPC Port

Defend your base ships against waves of Osirian attackers, up to eight at a time. They are smarter than the usual invaders: they dodge your missiles to either side and slip out of your line of fire rather than sit above your ship. A base ship is lost when one reaches the space directly above it or diagonally above it. Keep moving and keep firing.

Controls: Left and right move the base ship; fire launches a missile, with rapid fire as a menu option.
