Starmada

This is a great space action game! Starmageddon II – Return of the Starmada is a truly classic sequel, in the way that super mario bros 2 was a great sequel to the original super mario bros! The alien attackers from Starmageddon are back to have another go at enslaving humanity, and once again it’s up to you to stop them. In Starmageddon II – Return of the Starmada the developers have added a bonus system where you can earn medals.

Move your ship using either the mouse or the arrow or WASD keys.

Your guns fire automatically.

Activate your repulsion-wave with the left mouse-button or X or M key.
The repulser functions defensively by destroying all enemy bullets it touches and blocking enemy beam weapons.
It also has an offensive function, inflicting damage on all enemies in range.

An upgraded repulser can be an effective means of quickly annihilating large groups of closely packed enemies.

Dying enemies eject treasure worth money you can spend in the shop on upgrades, stars for extra points and power-ups which replenish health, increase lives, increase score-multiplier or activate shields.

Annihilate all enemies in a formation to gain a squad-bonus worth extra points.
Enemies armed with beam-weapons unleash a shockwave when they explode, similar in effect to your repulser, this can be helpful when fighting hordes of enemies.
