"Rails Undead" is a relentless survival shooter where you defend a speeding steam train against endless ravenous zombies. Armed with limited weapons, you must blast apart rotting hordes clawing their way onto the train while frantically collecting scattered coal chunks to keep the furnace burning—stop feeding the fire, and the train slows to a deadly halt. With no upgrades or respites, every second is a desperate balance between shooting shambling corpses and scrambling for fuel before the boiler runs dry and the dead overwhelm you. How long can you last before becoming another bloodstain on the tracks?
