No, mods are the work of the debil and god strangles a puppy every time someone mentions them. Seriously. Don't even
wish for mods. CoC has a sub-forum just for mods but they are UNOFFICIAL, and to my knowledge, no one has worked on any for CoC2 or TiTS.
Just the mere
mention of mods make the developers break out in rage-hives.
There is, however, a
Save Editor that allows you to tweak things like your character's stats and equipment, but it's more akin to using cheat codes.
