Probably the most complex thing I made back then. You controlled 4 different player characters at the same time in a turn-based sort of gameplay. The score and stats are broken here but you can get an idea.
First choose where you want to go from the map, choose wisely.
Each turn would let you select your character then move or attack from any vantange point in the time remaining for the player's turn (the spinning-sword clock in the corner). You can also use spells and objects from your inventory.
It was a very Stephen J Cannell time.
Find spells and add them to your spellbook. Some of these are unfinished, just as I left them 30 years ago.
