How To Complete the Last Delivery Order Quest in Zenless Zone Zero

Besides tackling the big commissions in the main story, you can also accept various small requests to level up your Inter-Knot account. Some are only a single short mission, while others are a chain quest. The Last Delivery Order commission is the last request in the Survivor Rescue chain quest. Unlike many Zenless Zone Zero missions, the Last Delivery Order requires you to solve several puzzles to complete it. Your goal is to lay down tracks and distribute medicines to survivors inside a Hollow. Although you can simply run to the endpoint, you also want to collect all the Gear Coins and other items to get extra rewards.

How To Solve Last Delivery Order Puzzle in ZZZ

The Last Delivery Order quest consists of four puzzle stages, with a regular battle at the end. While laying out the tracks, you don’t need to worry about being bothered by Hollow monsters; you can focus on helping the survivors. All stages also contain barriers that you have to unlock using switches.

Route 1

The first puzzle is the easiest one. You just need to activate the switch on the bottom part by laying a track through the TV. Then, you can head up to the survivor and head right to reach the finish point.

Route 2

After completing the warm-up puzzle in the previous stage, the difficulty increases slightly in the next round. Although you need to grab all the Gear Coins and survivors, you need to avoid walking through the Contamination zone.

Here are the steps you need to take to complete this Last Delivery Order quest puzzle:

1. Go down one space.
2. Turn to your left and head up.
3. Head to your right until you reach the switch.
4. Go down to grab a Gear Coin.
5. Turn to your left and go down again.
6. Head to your left to help a survivor.
7. Go down until you reach the edge.
8. Turn right and then up.
9. Finally, head to the left to reach the end.

Route 3

The third stage is much harder than the previous round since the switch is located in an awkward spot. If you want to get all the survivors and unlock the barrier, you need to make your way around the area.

Here’s how you can solve the third puzzle in the Last Delivery Order quest:

1. Head to the left until you reach the edge.
2. Go down, grab the Gear Coin, and stop at the corner.
3. Turn to the right until you reach the next corner.
4. Now, you need to head up and turn to the left to grab a survivor.
5. Next, you can go down until you are next to the previous track.
6. Go to the left until you can’t move and head north.
7. Turn to the right and pass through the switch.
8. Stop before the barrier and go down.
9. Turn to the right to grab another Gear Coin.
10. Lastly, go up to reach the finish line.

Route 4

Your puzzle-solving skill is going to be tested in the fourth stage. In the last round of the Last Delivery Order quest, you have to save four survivors, grab three Gear Coins, and avoid two Contamination rooms.

Here are the steps you can follow to complete the Last Delivery Order quest:

1. Go down one room and then turn left to press the switch.
2. Head up three spaces and turn right until you reach the edge.
3. Go up again and head left until you reach a corner.
4. Head down two rooms and turn right.
5. Go down to get a survivor and pass through the barrier.
6. Head down again and turn right until you reach another corner.
7. Go up until you can’t, and then turn left.
8. Finally, just go down one space to reach the endpoint.

Once you complete the four puzzles in the Last Delivery Order quest, you can collect all the rewards in the area. To exit the Hollow, you still need to face some monsters. The battle consists of two stages, with the second round containing an elite enemy wielding a bow.
