How to play Infected Shelter on Mac

"Dead Cells + Castle Crashers + executions = Infected Shelter Infected Shelter is a randomly generated rogue-lite post-apocalyptic action RPG shooter / dungeon brawler. Singleplayer and co-op for up to four players. Every run is different because of the randomly generated content. By beating enemies players can loot more than 150 different blueprints of permanent improvements and this is the key to Infected Shelter's replayability. Instead of just collecting loot to make yourself more powerful during a single run, you unlock new weapons, clothes, skills, relics and RPG-like character improvements that change how you play the game in the following runs."
