The official Solo Pro badge requires reaching 80 Km in a single run while playing solo. That proves substantial solo progress is intended, but it does not publish enemy scaling, checkpoint changes or a required class. A successful solo plan reduces handoffs: one compact bus, one sustainable weapon set, one fuel budget and only the detours that solve the next problem.
Build a compact bus
Complete the mobility parts, keep the burner and driver path open, and store fuel, spare parts, ammunition and objective items in reachable groups. Avoid a large structure that takes too long to repair or navigate alone.
Test every attachment before leaving. A spare wheel or its current recipe materials should be easier to reach than sale cargo.
Use a strict fuel budget
Check the gauge at every safe stop and preserve confirmed efficient fuel. Optional buildings are worthwhile only when they answer a named shortage. Turn back from low-purpose loot before the bus reserve becomes an emergency.
At terminals, sell true surplus and buy mobility before an unnecessary second weapon. Community full-run guides repeatedly identify fuel and inventory failure as major solo risks.
Carry one sustainable combat plan
Use a reliable melee option for ordinary enemies when safe and keep a supplied firearm for checkpoints or bosses. Match ammunition before carrying the gun and reload before entering an objective.
Do not fill the inventory with unsupported weapon variants. A single tested loadout plus healing and fuel is easier to manage than several empty guns.
Control checkpoint timing
Stop before the trigger, heal, reload, inspect the bus and park for visibility. Follow the live objective rather than an old wave count. Keep enemies in view and avoid a long chase that separates you from the vehicle or required interaction.
After completion, confirm the gate, reward or rescue state, then reset supplies. There is no teammate to notice the wheel or fuel you forgot.
Choose classes for self-activation
Compare Level 1 value and whether the role works alone. A starting kit, movement benefit or self-managed supply can be easier to use than a terminal bonus that assumes shared cargo. A restriction-heavy class needs a solo-compatible healing and food plan.
Do not assume an expensive class is required for Solo Pro. The official badge names distance and solo state, not a class.
Skip costly optional objectives
Anubis, Dracula and the Hospital can support badge goals but add risk and supply cost. On the first solo completion, take them only when the route is stable and the reward serves the selected plan. The Fred ending already requires preserving the main road reserve.
Record optional encounters on separate attempts once the 80 Km and completion route is reliable.
Choose the Fred outcome early
Solo gives full control over the final choice. For defeat, preserve the weapon and ammunition you have tested. For cure, protect the Cure Potion and follow the live interaction without continuing damage.
Do not let sale optimization consume the branch item or final reserve. Check the Endings guide before the last stop.
Recover from solo failures
- Bus stopped: increase fuel and mobility reserve; shorten detours.
- Checkpoint overwhelmed: park better, preserve ranged ammo and use shorter attacks.
- Inventory full: keep only current-function materials and sale high-purpose surplus.
- Final fight dry: protect ammunition earlier and use melee on ordinary enemies.
- Solo badge missing: verify no other player joined the active run and record the distance shown.
Solo record fields
Use class and level, bus layout, fuel sources, weapon/ammo, optional stops, checkpoint conditions, distance, Fred outcome, badge result, version and date. Route randomness should be recorded, not flattened into a guaranteed order.
Evidence level: the 80 Km Solo Pro condition is Official. Detailed solo route priorities are Community corroborated. Scaling, respawn, random stop order and class performance need in-game testing, checked September 18, 2026.
Pause points for a solo run
Use every quiet checkpoint as a deliberate pause. Confirm fuel, all mobility parts, loaded weapon, matching reserve ammunition, healing, inventory space and the next objective before moving. A thirty-second inspection is cheaper than discovering a missing wheel or empty magazine while enemies are active. Record distance at the same moment so the 80 Km attempt stays easy to audit.
