Necromancer is an action game created by Bill Williams for Atari 8-bit computers and published by Synapse Software in 1982.

The player controls the wizard Illuminar who attempts to grow an army of trees to attack Tetragorn the Necromancer and his evil minions that are trying to take over a graveyard.

Pressing the fire button plants a seed that will slowly grow into a tree in several stages to adulthood.

Here the player enters a five-level side-view map of a crypt filled with spider eggs.

Using the wisp, the player selects trees and moves them over the coffins where their roots grow into the roof of them and eventually break through to crush the eggs below.

The player must move through the vaults while all of this takes place, capturing question-mark prizes in order to extend ladders needed to reach lower levels.
