Vortex

Vortex is a science-fiction-themed space shooter for multiple systems.

The player controls a space vessels that travels along the bottom of the screen. As the shops moves laterally it banks to the left or the right, causing its laser fire to shoot away at an angle. Enemy vessels appear and fire towards the player. Getting hit drains shields, and if the player directly runs into an enemy craft they are destroyed. If the shield reaches zero, the vessel is also destroyed. After surviving a length of time against enemy fighters, the player enters an asteroid field where they must avoid incoming dangers. Game play switches between enemy vessels and asteroids until the player loses five lives.
