Transgression

In Transgression the player takes control of a hacker who has illegally
entered a series of computer systems and must fight against drones and
administrators. The game plays somewhat similarly to Joust. The player
controls the hacker, who is riding on some sort of flying cyber bike, on a 2D
plane which scrolls back and forth. Enemies enter from the sides and the
player hit them from above in order to destroy them. If the enemies hit the
player from above, the player loses a life. The player can reduce the amount
of enemies on screen by entering a portal. The player’s goal is to collect
eight computer chips, which will allow the player to proceed to the next level
by entering a portal. The player can get computer chips by destroy
administrators, who are riding in similar vehicles to you. The player starts
out with nine lives and can earn additional ones by destroying three enemies
in quick succession. Destroying ten enemies in quick succession will give the
player a temporary invincibility power-up. There is a 99 second timer which
counts down as the player plays, when the player proceeds to a new level the
timer is reset back to 99. Once the timer reaches zero or the player runs out
of lives it’s game over.
