Topologika are proud to present Peter Killworth's latest and greatest adventure. Return To Doom is part two of his developing Doom Trilogy - and is every bit as baffling as Countdown To Doom, one of the classic games of all time!

After surviving a deceptively simply beginning, you'll meet lots of original Killworth puzzles, alternative universes, werid weather, an empty field will never look the same again! You'll accrue a talkative four-legged friend who'll make you feel like laughing one minute and crying the next - maybe even both at the same time! The game ends with a danger-a-minute sequence that would even scare Indiana Jones (half) to death!

The top line contains a short description of where you are, together with your current score. The bottom section displays your current location in greater detail, together with your own input and the game's responses.

GO NORTH, THEN EAT THE PIG, E, SW, IN
GET ALL BUT THE DUCK AND GOBLET, AND LEAVE
GET - takes the first relevant object
DROP - similar
TAKE THE PIG AND UNICORN, WAIT
SAY HELLO
HELLO - equivalent to saying it
LOOK - gives a full description of where you are
SAVE - stores your current position on disk
RESTORE - brings back the saved game
RESTART - begins at the beginning
QUIT or STOP
VERBOSE - makes program always give the full description of where you are
NORMAL - makes program give full description the first time you arrive at a new place, with short descriptions for later visits
INVENTORY - lists your current possessions

You may be puzzled why the EXAMINE command is of only limited use. The game is conceived in such a way that in solving the puzzles you are not involved in merely happening to discover things about the objects. It is only by manipulating them where possible, or combing them in some way, that the relevant features are revealed. Some locations, however, do contain hidden depths...

If you get completely stuck, on-line help is available by typing HELP. Look up your problem on the list of hints and give the hint number you require.

You will then be given some sort of clue. The HELP facility is structured in stages so that you will initially get a partial clue, and will be given due warning if the entire puzzle is about to be revealed to you!
