...was that a reference to this Doom wad? (Note: please don't actually download and play it if you don't know what you're getting into.)
It wasn't a conscious reference to anything, but plain truth =)
Good to know (and quite obvious, now that I think of it) that I wasn't the first the make such a weapon in doom.
RE: Doom arena - if it is possible to trigger stuff by killing all enemies currently present, that would be great. I'll have to look into the possibilities. I'm sure the community have already made tools that allow you to do pretty much anything, though for now I will restrict myself to the basics and leave the more complicated levels for later.
I've finished entry (one version) and the unchained court.
The other easy ones are: Phobos Anomaly, Hell's Armory, City of Skulls, Spider's Lair, Tower of Babel, Unholy Cathedral, The Vaults (a switch will take place of teh staff), The Lava Pits and Dis, obviously without the unique enemis.
That will be quite a lot of work, I'll then probably try to make some "random" levels in between (seriously, going from entry straight to unchained court is crazy), so I have my work cut out for me for some time. Then I will worry about the scripting and stuff.
BTW, I'm not sure how the floors that lower into lava work, but if they are customizable, I should be able to make halls of carnage relatively easily. I already know how to make locked doors so yeah. That could be fun.
