Defend against Stitches... again! Rally as many troops as we can to assault the Hot Tub Slime Machine!
Use a Cycle or Squad Mini to waste the hook of Stitches and kill him. Use Quilboar behind the boss when your push is nearby to allow Unbound Minis to deal damage.
For every PvE mission, there is a campaign version and a Heroic version. When you first begin the game, you can only participate in campaign missions. Upon collecting 50 sigils, you will then unlock Heroic missions.
Campaign missions will grant rewards after the first successful clear with ANY family. Heroic missions must be completed with EACH of the 5 different families in order to receive the mission rewards.
