I know that no one is impressed with modified physics files, but that's basically what I've uploaded to Simplici7y:
While designing new enemies for some other maps I'm working on I came up with some ideas for "Bosses". But since I don't actually like boss battles, I'm not going to use them in any of my other maps, so I figured I'd share them as a separate little thing. I think they're fun, and I had fun making them.
Each "boss" does require a specially designed arena for him to work properly. The arenas in the map I uploaded aren't perfect, but they do provide the opportunity for the boss battles to play out the way I intended them to about half the time (if you're not cheesing the monsters or using invincibility).
Humor me, and let me know what you think.
