does anyone know where i can get a copy of this film?

There was a really nice widescreen VHS from Japan released in 1987 that I did manage to find on eBay, look for sellers using the names "Hontoni" and "SpiralHeadCase", they are both dependable & honest and have both had it for sale more than once. Spiral can often find stuff on request too though mine came from Hontoni, the quality of the tape is strikingly good though obviously not 16x9 format. If you get desperate feel free to message me and we can maybe cook you up a copy to tide you over.

I too am a fan of the 80's Italian actioner. Go to Amazon.de and type in cinema treasures. This company has several of these films.

Films available are (incomplete)
Blastfighter (AWE/ 88 films)
Killer Crocodile (AWE)
Bronxe Warriors 1&2/ New barbarians (Shameless/ Blu-Underground).
Rats: Night of Terror (AWE & I think blu-underground).
Iron Master (AWE).
2019 After the fall of new york (AWE).

Also Code Red is slowly releasing films by Cirio H. Santiago and Roger Corman. Similar vibe. They have released Equalizer 2000, The Sisterhood and Wheels of Fire. You can buy these at Screenarachives.com Happy spending broseph.

Here is the film you are after.
