Unlike most contemporaneous racing games, Revs features selection of aerodynamic settings by the player and a full three-dimensional environment. The player is allowed to drive the wrong way around the track or even away from it completely. Unusual for the time, the track and terrain are not planar, but undulations in the ground are reproduced. The game was noted for its use of the BBC's hardware in achieving its display: such was the difficulty in squeezing the game into the BBC's limited memory, part of the game code actually occupies part of the screen memory. Whilst this would ordinarily be distractingly visible, timer-based manipulation of the BBC's display palette has the effect of turning all the 'code pixels' blue, thus hiding it in the game's sky.
The game features rudimentary AI for control of the opponents' cars, which are driven by individual characters with humorous names. Johnny Turbo, Max Throttle and Gloria Slap are usually the fastest opponents, whereas Miles Behind is often the slowest.
An enhanced edition of the BBC version was released in 1986 by Superior Software/Acornsoft as Revs plus Revs 4 Tracks which included all 5 tracks. The enhanced edition also included a 'steering assist' driving aid "designed to improve control of the car when using keys or a digital joystick".[2]
Ports
Revs was later ported to the Commodore 64, with the standard game providing the Silverstone and Brands Hatch tracks. The '4 Tracks' pack for the Commodore (released under the title Revs +) included the Nürburgring, Oulton Park, Snetterton and Donington Park circuits.
