Limp Mode is a top-down zombie survival roguelite about keeping a broken car alive on an endless highway. Fuel doubles as the run timer, and every stop for gas, parts, or salvage turns into a fight. When a warning light comes on, the answer is an OBD diagnostic scanner: read the fault codes to find the failing part, clear them to limp on a little further, or disable systems outright to trade reliability for power and for noise the horde can hear. Handling leans toward simulation, with slip-based tire physics, weight transfer and drift behavior, and a proving ground behind the player's base provides a track editor for shaking down a build before taking it onto the highway. Cars wear out, leak and fail in ways that can be diagnosed and repaired, parts can be stripped from wrecks, and money and vehicles carry over between runs. The world persists after a death, so abandoned wrecks and emptied containers stay where they were left. It can be played solo or in co-op for up to four players.
