Alien 8 Remake is my Mac OS X port of Ignacio Pérez Gil's outstanding remake of Ultimate's (now Rare) legendary 8-bit isometric computer game.
Summarizing, your mission on this game is to activate all cryochambers scattered arround the spaceship. Those cryochambers hold all the ship's cyogenized crew, and you must activate all of them before the ship reaches it's destination, so you can wake up the crew before it's too late...
To activate each cryochamber, you must find the right thermolec valve and drop it over the room's energy cell. There are four different kinds of thermolec valves; an hologram over each energy cell will tell you the right kind of valve you need for each one. All four kinds of valves and the energy cell do look like this:
To control your robot, you can use a joystick, or the following keys:
Move: Cursors. Jump: Z.
Get/drop: X. Jump & get/drop: C.
You can redefine the keyboard too, and keep in mind you can graduate the jump's height and length, depending on how much time do you keep the key pressed.
