Endless Rails (끝없는 철로)

Touch/mouse: tap zombies to shoot (hold a press on the view or the shoot button for automatic fire with the M16, K2C1 and K16; the revolver and carbine fire once per press); the 4-step lever on the right sets speed (top to bottom: Full, Accel, Decel, Stop). Keyboard: W/S or Up/Down move the lever one step, Space shoots (hold to repeat), Enter departs. Zoom: pinch, the 🔍+/🔍- buttons, mouse wheel or +/- keys. Supply stops: up to 2 between stations. While the locomotive is in the yellow zone of a supermarket (food), gas station (fuel, parts), construction site (materials, parts) , hospital (medicine) or hypermarket (a little of everything but materials) at less than Full speed, supplies gather in 3 seconds, even while rolling. Stages: the top center shows only the stage number. Runners (orange eyes) appear from stage 5, brutes (blue eyes) from stage 10, bloated zombies (green eyes, three hits, explode on death, ignore the armored plow) from stage 15 and hidden zombies (no eye-shine; charge on all fours once a light finds them) from stage 20; walkers have yellow eyes. Tip gauge: zombies hitting the sides of the train fill the tip gauge instead of damaging the hull; at 100% the train derails and tips over. It drains back to 0% when the hits stop. Ammo: when the gun runs dry it clicks empty, then reloads 1 second later. Stations: inside a barricade; tap scavenging, locomotive, gun and headlight upgrades and train upgrade buttons. Higher locomotive tiers raise the headlight, turret, plow, greenhouse and fuel tank upgrade limits and the passenger car limit (2 per tier). One greenhouse and one fuel tank car only. Every passenger car, greenhouse and fuel tank attached lowers top speed. Train view at stations: swipe up on the station window (or press Up) to fold it and view your train; swipe left/right (drag, or Left/Right keys) to look from the engine to the tail car; swipe down (or press Down) to open the window again. v7: The train stops at the front end of the platform. The station window has Scavenge, Train (locomotive, headlight, passenger cars, greenhouse, fuel tank, cargo car) and Armament (gun, turret install/upgrade, armored plow, side armor) tabs. Every gun shows its rounds as cartridges that empty as you shoot. MG turrets fire only where the train's or guard towers' headlights reach and cannot go on the pump trolley. The cargo car (one only, upgraded up to the locomotive tier) sets how many supplies you can carry and slows the train a little. v9: Each departure may bring rain (turrets miss more), snow (the locomotive slows) or fog (the headlight reaches less far). Head-on zombie hits slow the train briefly. While viewing the train at a station, tap a car to zoom into its interior; tap again to zoom out. Each supply has its own max storage, raised by the cargo car.
