this mod, once activated, will slaughter ALL spiders EVERYWHERE, vanilla, SCP, fan missions, it just won't care. a worm will be spawned at their place. pre-placed spider corpses will also be removed.

note: if the level does something scripted with a spider, this mod will break it (no change there, the previously available mods that were removing spiders are not any different) - a good example would be the Eng2 Many sequence, while the spiders will be converted into worms properly, they will not patrol around like the spiders did (as that part is scripted on the spiders, and will die with them).

I have now set the spiders to be destroyed as soon as they are created. As a safeguard I've also set them to be invisible, completly silent, slower then your avarge dead slug, have one (1) hitpoint, have weapons that make no damage AND they are on the Good team so any other AI's around will slay them! That enough for ya?
