Bus Upgrades Tech Tree & Milestones
The bus is your squad's moving lifeline. Upgrade its engine to squeeze maximum mileage out of every coal chunk, and fortify its hull with heavy spiked cowcatchers to survive 95,000 meters.
Engine & Powertrain
Directly improves fuel-to-distance conversion ratio and bus top speed.
1.0x baseline fuel burn and travel velocity.
+15% distance per fuel item, faster acceleration.
+30% distance efficiency, reduced engine overheat rate.
+45% distance efficiency, ploughs through small zombie piles without slowing.
+65% maximum efficiency, horn stuns zombies in road path.
Armor Plating & Ramming Cowcatcher
Protects the vehicle hull, windshields, and doors from horde breach attacks.
Fragile glass, zombies shatter windows after 3 hits.
Prevents zombies from leaping through passenger windows.
Instantly kills standard Walkers upon impact; -15% ramming deceleration.
Reduces hull damage taken from corrosive and heavy attacks while the bus is swarmed.
Smashes through roadblock cars and crashed vehicles with minimal hull damage.
Roof Mounted Auto-Turrets
Autonomous roof weaponry that covers the rear and flanks during scavenging halts.
Mounts 360-degree light machine gun with 500 RPM auto-target fire.
Ignites rear area in continuous napalm stream, roasting pursuing sprinters.
Heavy anti-materiel cannon that staggers Brutes and Bosses.
Auxiliary Utilities & Lighting
Nighttime defense, furnace expansion, and squad convenience upgrades.
Doubles headlight cone distance for earlier obstacle warning.
Massively extends night visibility for driving and scavenging — critical on Nightmare Mode's permanent night.
Allows stacking up to 10 fuel items in furnace buffer queue.
Optimal Upgrade Order for 95,000m Extraction
Engine Lv 2 + Window Bars
Prioritize fuel efficiency first to stretch early coal supplies. Barricade side windows to stop fast infected from ambushing survivors while refueling. (Ticket costs are community-reported estimates — no official price list exists.)
Spiked Cowcatcher + Roof LMG
In this middle stretch you hit the checkpoint gates and the Graveyard where Dracula waits near Checkpoint III. Get the spiked cowcatcher for ramming abandoned roadblock cars and the roof LMG for automated crowd control before committing to boss fights.
UV Rig + Engine Lv 4-5
The back stretch offers fewer resupply stops and hides the optional Anubis dungeon. Max out your engine, carry every spare fuel unit, and keep one full buffer reserved for the final approach to the 95,000m Last Stop.
95,000m Environmental Route Checkpoints
Hazard breakdowns, recommended engine levels, and key rewards as you push through each segment of the route.
Opening Road
The stretch from spawn to the first Gas Station, where you learn the furnace loop.
Road Stops & First Terminal
Gas stations and roadside buildings lead up to the first Terminal around 12,000m.
Checkpoint Gates & Graveyard
Three checkpoint gates with a Key/rescue/loot loop between them; the Graveyard housing Dracula sits near Checkpoint III.
The Long Haul
The community-reported back stretch of the route, including entrances to hidden content such as the Anubis dungeon.
The Final Stop
The end of the line at exactly 95,000m, where Fred awaits — cure him with the potion for the peaceful ending or fight him for the kill ending.
