Great news, but thanks to the games author Simon Phillips, we have managed to preserve possibly one of the only copies and packages of the obscure Gamma Strike game set on the Commodore 64.
What is particularly interesting about this finding is the use of the two guns which shoot plastic pellets, and of which probably caused the downfall of the package and its very limited release.
Now, it is pretty hard to fully preserve this title because of the hardware packaged with it, but by time of the Christmas update we should have a semi-playable download version of the 3 games that you can check out. Also with this will be various high quality photos/scans of the hardware, box and technical details of how the target and gun worked (So maybe you could rebuild the thing! ) to completely preserve this wonderful obscurity.
Look out for the Christmas update of GTW64 for the full story and all the findings, but for now check out the current entry in GTW 64.
