Maybe it's my luck--maybe it's me doing something wrong but whenever I play, I've never seemed to have an issue with the Terror Level. I've never seen it rise above 3. Knock on wood but it seems I'm doing everything right too--killing monsters, so no Terror level there. I've never used Charlie Kane in a single game, so it's not like I've kept it from going up either.
Now, it's not like I /want/ it to go up or anything but I have to wonder if anyone else has noticed this or if this is a regular thing?
