It's Spectre, not Spectre VR. Though it is the same game with the same graphics, there are some levels not included in Spectre that is in Spectre VR. But it does have "The Arena" where every one goes after each other. And you can work it on AppleTalk. when I had that lab, I had it on 15 Macs (modified 512k w/2MB of RAM, 2 MacXLs, 3 SEs, 2 SE\30s all on a combination AppleTalk/PhoneNet network and I would plug in with my Duo 210 to cause havok. Those days were fun!
Spectre has a smaller game size than Spectre VR and fits nicely in a 68K Mac's 4 megs. Spectre VR would not fit on a 68K Mac.
As a test, if you can find the freeware version called "Spectre Demo" and run that on a Mac SE, then Spectre will work on it as well Spectre Demo is the same game but with 3 levels and no network play.
Remember to have it in B/W Mode with No Polygon Fills.
