Martian Gothic: Unification (a.k.a. Martian Gothic) is a survival horror game for the PlayStation and PC. It was developed by Creative Reality and published by Take-Two Interactive. Programmers Neil Dodwell and Martin Wong, designer Stephen Marley, animator David Dew, modelers Julian Holtom and Paul Oglesby, and music & sound effects by Jeremy Taylor. The PlayStation version was one of a number of "budget titles" released near the end of the system's lifespan that debuted at only $9.99 MSRP

A unique feature of this game is that if any of the characters meet face to face, the bacteria that has infected them draw all three characters into a 'Trimorph' at which point of the game is lost. Because the characters cannot meet face-to-face, they can trade items using a system of "Vac Tubes," which can transport 4 items to other Vac Tubes at a time. Also, when the player needs to leave an item behind, she/he may do so by leaving the relevant item into various hatches, which can hold up to 4-6 items. Using the hatches may leave the player confused about where she/he left the item, but the player can use any in-game computer to bring up a list of the contents of every hatch, including ones that have not been accessed yet. In order for the character to unravel the events before their arrival, they may search dead bodies for letters or micro-recorders which may contain information about the character, plot, passwords, and the method in which they might have died. Many recordings have been stored on some of the base's computers, which also contain information about the person or the storyline, to provide information that can further the player's progress through the game setting.
