Iron Lung is an acclaimed indie horror game that has inspired a film adaptation by Markiplier. The genre of vehicular horror is largely unexplored, with few titles like Barotrauma and Klekta. The Temple is an upcoming total conversion mod for Half-Life 2 that allows players to navigate a horror-filled submarine and expands the experience into space. It is part of MapLabs and promises over two hours of gameplay, featuring three vehicles and a visually impressive environment. The mod includes elements inspired by Amnesia: The Dark Descent, such as invisible water monsters and a talking crow companion. The creator, Klems, has hinted at a potential release "very soon, possibly next month."
