There’s a rebalancing mod that adds a lot of monsters mostly in the existing categories (some more zombies, lots more triffids, fungals, and ants, maybe some other stuff?).
There’s also a mod that adds the creatures from DOOM. That might be the same mod, come to think of it… I haven’t played with either of them, but they are interesting to read about.[/quote]
If you’re referring to pisskop’s mod, I believe they’re the same thing.
