Space Invaders

Your objective is to defend Earth from waves of alien invaders by controlling a laser cannon at the bottom of the screen. Move your cannon left and right using the control stick to avoid enemy fire while shooting upward to destroy the descending aliens.

The aliens move horizontally across the screen and gradually advance downward; if they reach the bottom or destroy your shields, you lose a life. You have three lives to clear all waves.

Collect power-ups that fall from destroyed UFOs to enhance your cannon with rapid fire, spread shots, or shields. Focus on eliminating entire columns of aliens first to reduce incoming fire, and prioritize shooting the UFO that occasionally flies across the top of the screen for bonus points and power-ups.

In tense moments, use the remaining barriers for cover while picking off aliens methodically to survive longer waves.
