Slay the Nereis

Slay the Nereis is a 1-player Centipede clone for the TRS-80 CoCo.

You are the commander in charge of three mini-subs. During your mission, you soon discover that the area you were sent to scout is a dangerous one, teeming with several innocent looking creatures. Schools of fish, manta rays, starfish, jellyfish, and an occasional "Nereis", a marine creature which excretes a paralyzing poison.

The player controls a small sub at the bottom of the screen which can move in all directions, and partially up the screen. Numerous enemies stream towards the player, including schools of fish, which move laterally, and descend one level when they reach an obstruction. A new stage is reached by shooting all fish in the school.

The game is over when all subs are lost.
