What'Sub is a co-op action game where you and up to three friends run a submarine crew hauling coffee across the ocean floor. You'll need to keep your aging sub operational while navigating hazards and hostile encounters. The core loop involves coordinating crew roles—managing repairs, steering, combat, and cargo—as systems break down mid-voyage. Each run challenges you to balance maintenance against forward progress, since stopping to patch leaks means less time outrunning threats. The coffee-pirate premise leans absurd, but the mechanical demands are real: ignore a flooded compartment or a busted engine too long and you're sunk. Success depends on clear communication and quick role-switching when chaos hits. Best suited for groups who enjoy frantic cooperation over careful planning.
