This is a challenging, old-school, retro, side-scrolling shooter. You must defend your base, against the onslaught of alien attackers.

Features:

Radar of entire playfield, shows where threats exist
Picture in picture view of the base, so you can keep an eye on it
28 waves
16 power-ups. Power-ups can be combined
10 bonus twin-stick shooter levels, starring Hitch, the security robot, take place under the base. Many enemies on these levels are spawned by generators, that must be destroyed. Ensects attack power generators, damaging the base. There are gas outlets that cause large explosions, if shot.
Multiple weapons, including: Lasers, Bombs, and the dreaded Sonic Bomb, which can mass-kill enemies
Many enemy types, each with unique abilities, including one whose weapon can be stolen
Boss battles
Snow, thunderstorm, and darkness environments. Dark environments must be lit with flares
AI-powered wingmen can be summoned to assist. Careful, they can be turned against you
Rock launchers help you defend the base. You can pick them up and re-position them with your ship
You can escort evacuation ships to the opposite side of the playfield. If they escape, you are rewarded with resources. Supply landers can be brought to the base for more resources.
Defensa- your ship's computer voice. She informs you when you activate power ups, warns of threats, and makes comments about the unfolding events
Original Soundtrack- original soundtrack written specifically for the game by six different composers
Optional arcade style controls, where the joystick on the gamepad only moves your ship vertically. Horizontal movement is done via thrust and reverse buttons
Randomized waves - no two waves are the same, for improved re-playability
New Endless wave mode- One increasing endless wave with all regular enemies. How long can you last?
New upgrade store - collect metal from destroyed enemy ships to purchase upgrades and supplies for your ship.

A gamepad is recommended.

Photosensitive seizure warning
Thunderstorm levels have lightning flashes in the sky (you are able to turn off flashes in the options screen).
A very small percentage of people may experience a seizure when exposed to certain visual images, including flashing lights or patterns that may appear in video games. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can cause these “photosensitive epileptic seizures” while playing video games.
Immediately stop playing and consult a doctor if you experience any symptoms.
