Button Down: Twin Pack

Two buttons on one threadA twin button is the plain button and a partner button tied together by a single thread. You steer only the plain button. With the thread slack, the partner slides to a stop; pulled taut, it is dragged along — and turn sharply, and it swings wide. You start with both starter weapons. The partner's two exclusive weapons fire from the partner. The partner can be hit too, and the two share one health bar — the price of a second pair of hands.

Weapon cards come from 8: the two buttons' 4 exclusives plus the 4 shared weapons. Twin · Pearl — needle and rubber band. Slow them down, then both of you shoot. Twin · Maroon — pencil lead and keyring. Pierce and sweep. Twin · Gold — coin and bottle cap. The partner blocks up front while you fire from behind. Twin buttons work in every chapter of the base game, whether or not you bought the partner button there. Two 40-minute chaptersA button that lost its pair, finding its way through the washing machine and back to the coat.

Both chapters reach their boss at 36 minutes and follow the same four difficulty bands as the expansion chapters (easy to 10 minutes, average to 20, hard to 30, then a steady climb). Elites arrive every 5, 11 and 20 minutes. Washing Machine — Lost Sock, Hairpin, Soap Suds, Soggy Tissue, Coin Purse.…
