Fracas

Fracas is a Shareware Mech Fighter from Casco/John Smith on the Amiga. It says in the readme this took 3 years to make.

Basically you have to search down the enemy/ies and destroy them on each generated level. The game also offers a 2 player mode but suggest you use something to split the screen to stop your opponent cheating.

You do have a selection of different mechs too. This is a nice game I have only just discovered 28 years later.
