Scapeghost

You were successful police officer Alan Chance, until you were killed during a raid on drug dealers, who managed to take a hostage in the process. People have assumed that you died as a result of your own mistakes.

Now you have returned as a ghost, with psychic powers in place of your physical ones. Starting out at your own funeral, you must follow conversations to find clues. One early task is to find items which boost your physical abilities. You have help from other deceased beings, starting with pub owner Joe Danby.

Scapeghost was Level 9's final adventure game, and it is in the same format as the existing ones, which makes for a text parser with additional graphics. Puzzles require instructions to be given to other characters. The game is split into 3 days, each of which can be played independently of each other - November Graveyard, Haunted House and Poltergeist.

Level 9 Computing went out of business in 1991. To my knowledge, no one owns the copyright to L9 games anymore and they are truly abandonware.
