Twisted Minions: Rules to Spice up Your Encounters with Minions in Four Against Darkness

From BoardGameGeek:

Not just the same goblins again. Twisted Minions is a supplement for Four Against Darkness that adds a spin to minion encounters. Using a d100 table, you will create complications and unexpected twists every time you encounter a group of minions. Zombies are slow, but this time they ambush your party and gain the initiative; orcs fear magic, but those orcs have just robbed a wizard's library; those kobolds seem harmless, but they can call a medusa for help...?Features: 106 twists for minion encounters; The Prisoners scenario, for when your party is captured; Tables for chaos abilities and unusual treasure; 6 Minion Secrets. This is not a stand alone game. This supplement for characters of all levels requires the Four Against Darkness core rulebook. -From publisher blurb
