Gloomhaven: Buttons & Bugs is a solo play game, with an original campaign story written by Isaac Childres, that features a playstyle similar to Gloomhaven in a fraction of the size.
Each scenario is a single card, pitting one mercenary against a handful of enemies with simplified actions and AI. Each mercenary has a hand of just four double-sided cards, but they can be used twice — both the front and the back — before they are discarded. Attacks are resolved using a die in conjunction with a modifier table, and both the table and the mercenary ability cards can be improved as you level up throughout the campaign.
