Martian Memorandum is a nice talking and animated game.
=======================================================

It is a police quest in a Science fiction Background with good pictures.
(Under a killing moon is a new episode)

Here are some advice and a complete walk-through. Please forget any
mistakes I may have done here.

To complete the game, be aware that there are several traps, where you
can miss a very important clue and not be warned. For example, you can
leave to Mars, and not have the address of Big Dick's Casino, if you
miss a very small item. You will be stuck on Mars, and you cannot go
back ! I was stuck on this for several months, and almost gave up.

Also, save the game very often. In most of the situations, you are safe,
but there are some dangerous places where you can get killed, and some
other where you WILL get killed as soon as you move in the wrong direction.
(Junkyard, Jungle, Pyramid, Big dick's office).

To move, deselect all the icons and then use the mouse to move around.
There are several screens where the land extend farther than the screen.

When you talk to someone, you may have itemized answers, or just 
'ask about'. In the first case, explore all possibilities after saving
the game. My solution may be incomplete there. In the second case,
ask about everyone. If you get a new name, ask again, you may get 
some more information (An address, most likely).

You may do some blackmail, when you get a compromising clue on 
someone. This works well.

Well, here is the solution :

Don't read next page if you are not stuck in game !
