Ok that's the most awesome thing I've seen in ages for Doom. If you've not already, go play "house.wad". That is an experience in itself.
Wow, I've just spent some time playing "myhouse.pk3", and it's not what I thought it was at all. Google found a site with this Doom level, with both '.wad' and '.pk3' formats, so I tried the .pk3 version, as I thought it might be better or more advanced.
I take it this is the level that you mean? It starts out like a normal Doom level, you are standing outside a house, but inside it's fenced garden, you enter the house, you fight zombie pistol men, zombie shotgunners, imps, and pinky demons, then it becomes.... surreal. It's really well done (I've not tried the .wad version yet, can the standard Doom engine, via a .WAD file, do these things?), and I don't think I've seen a Doom level or mod do this before (I'm not mentioning spoilers here, in case anyone else decides to try it).
At first I thought the title "My House" was bad, as it was so generic. But I see now that it was meant to lull you into a false expectation that the mod would be an unimaginative and straightforward mod.
When I get home, I'll carry on with it, see how deep it goes. Thanks for the recommendation, mate.
...It just looks like a Doom 1 mappack for D64, with a few extra additions like the cut D64 enemies returning.
Yes (and Doom 2, and TNT, and Plutonia, and many-fan made levels are presumably compatible, too), but I feel that the Doom 64 aesthetics are extremely atmospheric, and really immersive, so this is something I will keep in my Doom installation.
