Rules just about the same, was said by spooky in one of these threads...

Sounds like they just enabled the last three reels for Halloween..

Cute retort but looks like all of Halloween's shot entrances can be seen by the player, no shooting blind under the ship like Popeye.

Call some distributors and see what they can do.

Yeah and prototype TZs have art scraped off inserts. Nice eye but ultimately meaningless, they'll fix it when they order parts in bulk.

They both sold out nearly simultaneously, I think Spooky nailed the ratio perfectly.

The code is essentially the same for both games, only the assets and text will be changed. Guessing the junior programmer might do some of the conversion to UM. If the asset filenames are kept consistent between both games, not much really needs to be changed.. just the text on the LCD at that point.
