Eggs-it is an arcade game where you play as a small vehicle which can move left and right, while monsters steadily scroll towards you. Monsters come in two types: Alien creatures worth 10 points which come out of holes in the ground, and bird-like creatures worth 20 points which attempt to drop eggs on the player. The player can shoot forwards to destroy aliens, and can shoot vertically to destroy birds. A large flapping bird in the middle of the screen with intermittently swoop towards the player. Vertical shots will fall back to the ground if they do not connect with a monster, allowing the player to shoot themselves.

When the player is shot, the vehicle will catch on fire and move to the center of the screen, and the driver will fall out. An ambulance will then drive to the center of the screen to pick up the driver. The player has 3 lives, and it's game over when all are lost.
