Spellcast is a multiplayer strategy game for Unix machines running X windows. It concerns a conflict between two or more powerful wizards. The opponents use mystical hand gestures to invoke their spells -- spells of summoning, elemental energy, protection, psionic influence, and good old-fashioned brute force. Each wizard has two hands, a sequence of gestures can contain multiple spells, and some spells require two-handed gestures. This means that timing and forethought are necessary to insure that your defensive spells block all attacks while your attacks get through.
