Give this a try for the Amiga version. Just scroll down the page. It is a German site but hey what can you do? I would recommend that you give the Speccy version a try through the emulator if you don’t like this game as it may be that the original was better. In the prototype version the playing screen was simply on 1 screen with no scrolling, like bomberman. The full version was designed to be a bigger playing field but didn’t work as well in my opinion. As far as I am aware, this version (Total Chaos) is in keeping with the prototype version (just 1 screen). Anyhow I am rambling again so give it a try.
There is another game further up the page called ChaosHeavy, I have no idea if this is part of the same game/family.
