Slime Heroes is a two-player, area control slime game. It was originally inspired by the designer's favourite game Splatoon 2. Players battle by manipulating their slime on the board and expanding your area. Each player has an action deck of 16 cards. There are four types: place a color, place a bomb, support actions, and specials. The game ends when both players run out of cards. The player with the most colors wins.
