Okay, this one is a real oldie.

Hase & Wolf?

Nope. At least that was not the name it had back then.

Polyplay?

No, sorry. This appears to be a fishy one :-p * wink wink, nudge nudge*

Piranha?

Not yet, but quite close. It wasn't an arcade release, but a 8-bit tape.

Damn, can't make it an easy oner, I see. :P

:)

Snack Attack?

Probably not, but eh, may as well take a stab.

Well, I thought this would be easier; as there were not that many titles released here in spain back in the 80s, I assumed this one would be at least mildly popular. Here's a hint: it was a C64 game (although I think there was a spectrum port as well)

Pakacuda.

Whew! I thought I'd had to call time or something. You're correct.

New game gogo :)

ok.

one of the empire games?
