Gameplay

The player controls with the mouse, a black marble through a labyrinth -type structure levels, referred to in the game " landscapes". Knocks the ball against a so-called " oxyd stone ", so this opens and displays an icon. Pushes it to the neighbor, then the previous closes again when the two symbols were not identical. Successively two oxyds opened with the same symbol, they stay open. A level is solved when all pairs of tiles contained therein were opened. Numerous obstacles ( precipices, walls, ice and water areas, and more. ) And the simulated inertia of the marble make access to the Oxyd stones and must be overcome in part by creative combination of game elements, partly through clever mouse control.

Every tenth level is a so-called meditation landscape. These levels are achieved by four are placed at the same time with the mouse to be controlled smaller balls in a respective trough.

Multiplayer

Oxide and its successor oxide 2 can also be played via null-modem, modem, or the MIDI interface of the Atari ST to two computers. A player controls the black marble, the other one white. The two players do not act against each other, but to solve the landscapes together; in it there is usually game elements that can only be operated in each of the black or white marble.

Evolution of oxide - game series

Oxide was the first game of Schneider company Dongleware GmbH. It was freely distributed as shareware with a restriction on the total of twenty two hundred landscapes. The unlock code necessary for the continuation game were recorded in a available for DM 60 codebook, which thus acted as quasi dongle copy protection and next to it contained useful game tips. The game was developed first with Megamax Modula-2 on Atari ST systems.

Oxide ( 1990), and oxide 2 (1991 ) were also developed on the Schneider, but displaced by Application Systems Heidelberg Esprit ( 1989) established, but offered in addition to the two-player mode, a larger number of game elements. 1992 oxide has been ported with minor changes under the name Oxyd General Edition for MS -DOS, Amiga and Macintosh computers.

Oxyd magnum was released in 1993 for Atari ST, Amiga, Macintosh and MS -DOS. In this game, has been waived, the code book and the two-player mode. Oxide 2 was released in 1995 in a newly programmed and visually revised version under the name Per.Oxyd for MS-DOS and Macintosh. Per.Oxyd offered an additional game mode in which the two-player landscapes could be solved by one player alone. Oxyd Extra was released in 1996 for MS- DOS and Macintosh.

2002, the distribution of the oxide games from Dongleware publisher has been set, the series was abandonware.

Successor

Remake of Oxyd Extra

In 2005 there was a new edition of the previously released for MS- DOS game Oxyd Extra for Microsoft Windows. This in collaboration with Mad Data developed by Jens Duttke and released as freeware version offers ten new single-player landscapes and the opportunity to play oxide in the local network with two computers.

Open -source edition Enigma

A game technically identical open- source version of oxide is released under GNU General Public License ( GPL) as Enigma. Enigma can handle an extra special feature of the landscape directly as data in the original versions of oxide Per.Oxyd, oxide and oxide magnum and play a lot of the levels and functionally correct. In addition, Enigma provides the ability to write their own landscapes in the Lua scripting language. So over 1000 landscapes of different complexity have now arisen for Enigma. A special take a while those levels that are modeled after the game Sokoban. In this case, the player will also demanded a lot of sensitivity in the control. Enigma offers no real two-player mode over the network. Since November 2011, an unofficial port of Enigma for Android is available, in which the ball is controlled by tilt sensors.
