Bob The Schizo is the more complete version of the game
Bob The Schizo Lite. The main difference with the Lite version (apart from the 56MB it takes up) is that it comes equipped with many more sound effects, and much more ambient music.
For the rest, Bob The Schizo isn`t much different from the Lite version. You have to go through different cities across the world, via many levels (just like all pure platform games, but with much more action than normal).
In Bob The Schizo you have more than twenty different weapons (some simpler than others, from catapults to machine guns). These weapons let you fight and kill all your enemies you find in these cities. The arsenal you have isn`t just to destroy or kill, as you also have elements to protect you (like shields) from the attacks of your bloodthirsty enemies.
