Acid Drops is a simple arcade game with an abstract scenario. With no plot to describe, the player is only told how to shoot, what to shoot, what happens when they shoot and the consequences if they don’t!
There are three types of enemy to blast out of existence – moths, pods and spinners. Moths will drop bombs on the players ship, whilst pods and spinners will fire homing missiles. To cap it all, a leaky bath tub full of acid sits at the top of the screen. A gateway slowly opens on the right side of the screen, and the faster the player destroys the aliens, the sooner the gateway will open. Once through the gateway, the player then has to navigate a maze before they can reach the next level.
