Don’t Look Back features supporting characters. Basically they’re NPCs who need to dragged around and/or eaten, but don’t get to play the heroes. The box comes with some tokens for them, but mixing models and tokens for characters never feels right to me.
Fortunately, one of the expansions available is this set of six models, along with some extra rules crunch. If nothing else, it’s a couple of modern civilians to fill out whatever random modern ruleset I might get into.
