Quick Answer
Doomsday Express is the shipping and raiding activity with individual trucks and alliance freight trains. Inspect the cargo, refresh cost and escort before sending a shipment. Use raid attempts on targets you can reasonably beat, and claim daily task rewards before their deadline.
It is different from Doomsday Open and from Supply Convoy. Convoy handles eligible donations between alliance members; Express has its own shipments, rewards and combat.
Separate the Three Jobs
| Activity | Your decision | What to check |
|---|---|---|
| Personal shipment | Dispatch a truck with worthwhile cargo | Quality, actual rewards, escort and remaining sends |
| Raid | Challenge another shipment | Defender, cargo, eligible attempts and state rules |
| Alliance freight train | Coordinate a shared departure | Alliance eligibility, conductor, boarding and preparation timer |
Express arrived through a staged rollout, and later updates added alliance shipping and promotional reward periods. Your visible limits can differ from an older chart or a player with a seasonal benefit.
Send a Truck Step by Step
- Enter Doomsday Express and open your shipment panel.
- Inspect the available truck's quality and reward preview.
- Decide whether to use a Supply Refresh Voucher before dispatch.
- Select the escort formation and review its actual strength.
- Confirm the shipment, then return for its arrival and any completed tasks.
The August 2024 reference format allowed four shipments daily, with randomly assigned quality and voucher rerolls. Its chart distinguishes D, C, B, A and S trucks. Later seasonal passes have offered extra slots or attempts, so four is a reference baseline rather than a universal maximum.
Choose by the cargo your account needs. A large food quantity is not interchangeable with a small supply of a material that blocks your next upgrade. Also check whether a crate is random or lets you select its contents.
How Much Should You Spend on Rerolls?
Set a voucher budget before starting. A better-quality truck can be attractive, but a reroll is not a guaranteed improvement to the specific reward you want.
Suppose you have six vouchers and four shipments left. You could reserve one attempt for each shipment and hold two for a particularly poor result. That is a budgeting example, not a claim that this distribution maximises expected rewards; the current probabilities and cargo pool would be needed to prove that.
Stop when the available cargo meets your target or your voucher allowance is used. Chasing one perfect truck can consume the refresh supply you wanted for later sends. During a verified double-reward window, reassess the budget against the tagged rewards rather than assuming every future day has the same value.
Raiding Without Wasting Attempts
Inspect both cargo and defender. A valuable truck guarded by a formation far beyond yours is not automatically a good target. Compare previous reports against similar opponents and confirm that the intended heroes and supporting systems are selected.
The documented truck rules allow losses of the cross-marked reward items when defeated, with immunity after two defeats in that format. A truck continues toward its destination; it is not simply aborted because it loses a raid. Check the shipment history to understand which rewards remain.
Use the state-truck filter where your attack screen provides it, and follow any agreed state restrictions. The battle report guide helps distinguish an unfavourable matchup from an empty or outdated preset.
Do not respond to an Express loss by attacking a player's settlement without understanding the separate consequences. The two actions have different objectives and risk.
Freight Trains and the Conductor
Alliance freight shipping adds a shared timetable. The established workflow uses an R4-or-higher appointment for the conductor, who organises escorts, cargo and boarding before departure.
Before announcing a train, officers should verify:
- The freight feature is unlocked in the state and the alliance meets its membership conditions.
- The conductor is available for preparation and departure.
- Members know the boarding deadline and whether joining restricts leaving the alliance.
- Escorts and cargo have been confirmed before the preparation clock ends.
Older documented rules include a four-hour preparation period. Use the actual train timer rather than subtracting four hours from an assumed universal daily departure time.
Later Dig for Treasure rules introduced additional trains through a Freight Train Pass or a Rail Rush purchase. Those rules gave the free train departure priority and required the conductor to be in the current state for successful departure. This means the older “one train daily” baseline is not a complete description of every edition.
If you plan an alliance change or cross-state activity, resolve train participation first. Passenger restrictions and the conductor's later exception should not be treated as the same rule. The alliance guide covers planning membership changes around ongoing activities.
Double Rewards: Three Different Deadlines
The 1.23.600 double-reward format distinguishes dispatch, tagged raid targets and task claims:
| Reward | What preserves the double reward in that format? |
|---|---|
| Your shipment | Dispatch during the promotional window; arrival can be afterward |
| A raid | The truck carries the double-reward tag |
| Daily tasks | Claim before the promotion ends; unclaimed task rewards expire |
Do not delay claiming a task because an in-transit truck can finish later. Those are different rules.
This is a named promotional format, not a permanent doubling of all Express rewards. Check that the event is active on your account and the relevant tag is present.
Troubleshooting
The train is missing: check state rollout, alliance eligibility, appointment and preparation status. An old screenshot does not prove your alliance has an unclaimed train.
A truck's final rewards are smaller: inspect its raid history and the crossed-out cargo rather than comparing only its starting tier.
A formation looks wrong: reopen the selected lineup and supporting equipment. Patch history includes display fixes for vehicles, so distinguish an interface discrepancy from an empty assignment using the report and current client.
Leaving the alliance is blocked: inspect active train participation before treating it as an account error.
F2P and Spender Tips
F2P: use available shipments, sensible raid targets and free task rewards consistently. Save refresh vouchers toward useful cargo instead of chasing the highest letter on every truck.
Spenders: price any extra train or seasonal benefit against the shipments you will actually use. Coordinate purchased alliance activity before paying; a pass does not ensure people are available to board.
FAQ
Is Doomsday Express the same as Supply Convoy? No. Express uses shipments and raids; Convoy handles eligible alliance donations.
Can I cancel a truck after it is attacked? The documented truck format runs to its destination rather than offering an early abort.
Are there always four trucks per day? Four is the older reference allowance. Seasonal benefits and editions can change the visible limit.
Do all double rewards remain claimable after the event? No. The 1.23.600 rules preserve qualifying shipment and tagged-raid rewards, but unclaimed daily task rewards expire at the event's end.
Key Takeaways
- Budget vouchers around useful cargo and remaining shipments.
- Coordinate freight boarding and state travel before departure.
- Read task-claim deadlines separately from shipment arrival rules.
