Invaders to Earth

Alien ship combat

Invaders to Earth is a PC shooting game about defending Earth from alien warships. You shoot ships as they form up and attack, working through 50 levels that gradually increase in difficulty.

Scoring and power-ups

Destroying a ship in formation earns one point; the large ship at the back is worth five. Attacking ships are worth three points and may drop a power-up: an extra life, rapid fire, a temporary shield, ammunition that damages nearby ships with explosions, or a speed boost.
