Developer Shiny Shoe is holding a technical test for Inkbound, its upcoming fast-paced, cooperative tactical RPG roguelike. And ComingSoon is giving away 10 batches of three codes on PC.

Shiny Shoe is best known for Monster Train, a card-based roguelite in the vein of Slay the Spire that sits at “Overwhelmingly Positive” on Steam. Inkbound is a bit different than that, though, as explained in the above combat overview.
