Sol Invasion

In Sol Invasion, a fleet of space ships has to shoot down invading enemy waves. The basics are simple: the player controls a reticle, highlights an enemy with it and shoots either guns (short range) or missiles (long range) in order to kill it. Additionally the player can instruct allies to aid the fight: either the fleet attacks the highlighted enemy or the fighters distract it. Each killed enemy rewards resources which can be used to upgrade the weapons, upgrade the fighters or call reinforcements. While most of the game is spent by strafing the reticle over the screen, it actually takes place in a three-dimensional fleet. This means the player sometimes has to use the thruster to move closer to the action. By pressing a button, the ship automatically aligns to the next enemy. Being hit by enemy fire reduces the crew which basically acts as health. The goal is to to survive as long as possible and earn points for the high-score list.
