The Turrican clone you're talking about may be "Land of Genesis". A German review (including some screenshots) can be found here
Short version of the review: Impressive intro- menu and background graphics, poorly designed enemies, bad sound, technically flawed.
Abuse is a PC title, a "sort of Turrican clone". The sources were GPLed about 5 years ago it was then ported to the Amiga by the Frieden brothers. The executable can be found on Aminet, it requires the data files (either shareware or commercial versions) of the PC version.
Abuse was praised by the PC press when it was originally released.
