The Summoning

A single player, shareware point-and-click adventure game created by Asa Margetts in 1994. There's a reward out the summoner who roams the streets and haunts a sky scraper and murders people at random. Defeat him and not only could you save millions of lives, but you could also find a reward of about 500,000,000 pounds coming your way! You begin in the sky scraper he is known to roam it is also known that he's not human or if he is, has one weak spot where he/it can be stopped (maybe). Find him and finish him, the summoner is out there.
