Game versions
The first version is known as ''Walken'', the version which Ken Silverman sent to companies for evaluation. This was the first version created, and therefore it had very few features. There was almost no interactivity, and the code was mostly a test.
The first version to be released was a modified version of ''Walken'' called ''Ken's Labyrinth''. Many changes were made, including interactivity, an early money system and music. It was sold by Ken directly, using the
Advanced Systems company name, a company that Ken's older brother Alan Silverman was involved with.
Following that was version 1.1, which featured 27 levels and an alternate final boss. New enemies, textures and music were added, as well as a money system with which the player could locate money and use it to purchase a random item from a
vending machine
A vending machine is an automated machine that dispenses items such as snacks, beverages, cigarettes, and lottery tickets to consumers after cash, a credit card, or other forms of payment are inserted into the machine or payment is otherwise m ...
. Slot machines were also implemented. The game was then submitted to fifteen different software companies, including Silverman's later employer
Apogee Software, which appreciated the engine but requested considerable changes to the game.
Released in March 1993 by
Epic MegaGames, the final version (2.01) featured 30 levels, and many new features that older versions of the game lacked, such as the ability to choose the item purchased from the vending machines, a difficulty option (on "easy" mode, or "Don't touch me", enemies do not use
melee attacks, while on "hard" mode, or "Ouch!" they charge into the player and cause damage), an episode select, and also new enemies, textures and music with additional artwork made by
Misko Iho of
Future Crew.
