We are removing upgrade timers, and Spare Parts is what makes it possible.
Throughout Update 12.4, we will be running a series of highly ambitious tests. This experiment targets a core system that has been in place since Day 1: robot upgrades. Because of the balancing risks involved, it is entirely possible we may have to scale back or even scrap the idea. However, if everything goes smoothly, this feature will bring the War Robots upgrade system up to modern standards and pave the way for significantly faster gear progression.
Here is how the Spare Parts feature will improve the upgrade system:
- It eliminates the need to constantly watch upgrade timers.
- It significantly slashes the total time required to fully upgrade a robot or weapon.
- It flattens the steep spike in MK1 timers, making your progression feel more logical and rewarding.
NO UPGRADE TIMERS
On accounts with the new system enabled, robots and their equipment can be upgraded instantly at the press of a button, just like Titans. To balance this, each upgrade will require a specific amount of Spare Parts alongside its usual Silver cost. This feature allows us to maintain a healthy sense of progression while cutting out the tedious, time-consuming wait.
WHAT ARE SPARE PARTS?
Your Workshop automatically produces 1,500 Spare Parts per day, just a notch over one part per minute. They represent the work time of your hard-working hangar drones that used to facilitate robot upgrades.
Accumulating enough Spare Parts to max out an item is significantly faster than waiting out traditional timers. Let’s take a look at the preliminary numbers for a Tier 4 robot:
| Item Level | Minutes | Spare Parts |
| 1 | 120 | 100 |
| 2 | 300 | 300 |
| 3 | 840 | 600 |
| 4 | 1,680 | 900 |
| 5 | 3,960 | 1,200 |
| 6 | 6,120 | 1,500 |
| 7 | 7,440 | 1,800 |
| 8 | 8,400 | 2,100 |
| 9 | 8,880 | 2,400 |
| 10 | 9,120 | 2,700 |
| 11 | 9,600 | 3,000 |
| 12 | 0 | 0 |
| 1 | 720 | 3,000 |
| 2 | 1,440 | 3,000 |
| 3 | 2,160 | 3,000 |
| 4 | 2,880 | 3,000 |
| 5 | 2,880 | 3,000 |
| 6 | 2,880 | 3,000 |
| 7 | 2,880 | 3,000 |
| 8 | 2,880 | 3,000 |
| 9 | 2,880 | 3,000 |
| 10 | 2,880 | 3,000 |
| 11 | 2,880 | 3,000 |
What used to take 83,820 minutes now takes 49,600 Spare Parts, which take roughly 47,600 minutes to produce.
The same time-efficiency applies to Tier 4 weapons:
| Item Level | Minutes | Spare Parts |
| 1 | 120 | 100 |
| 2 | 300 | 200 |
| 3 | 840 | 400 |
| 4 | 1,140 | 600 |
| 5 | 2,400 | 800 |
| 6 | 4,080 | 1,000 |
| 7 | 5,160 | 1,200 |
| 8 | 6,480 | 1,400 |
| 9 | 7,200 | 1,600 |
| 10 | 7,680 | 1,800 |
| 11 | 8,160 | 2,000 |
| 12 | 0 | 0 |
| 1 | 720 | 2,000 |
| 2 | 1,440 | 2,000 |
| 3 | 2,160 | 2,000 |
| 4 | 2,160 | 2,000 |
| 5 | 2,160 | 2,000 |
| 6 | 2,160 | 2,000 |
| 7 | 2,160 | 2,000 |
| 8 | 2,160 | 2,000 |
| 9 | 2,160 | 2,000 |
| 10 | 2,160 | 2,000 |
| 11 | 2,160 | 2,000 |
Here, 65,460 minutes of upgrade time are substituted with 33,100 Spare Parts. While these numbers will likely change after initial testing, the core logic remains the same: faster upgrades across the board and no steep increase in wait times around late MK1.
HOW TO GET SPARE PARTS?
The primary source of Spare Parts is the Workshop, where they have their own dedicated production slot. To move them into your storage, simply claim them from the assembly line. You can grab them fresh out of the oven in small batches, or wait for them to pile up. Just keep in mind that once your production slot hits 1,500 Spare Parts, progress will pause. You'll need to collect the produced Spare Parts before your workshop drones can get back to work.
MANAGING UPGRADES EFFICIENTLY
The new system also eliminates the need to constantly monitor upgrade timers of varying lengths, a change that is especially noticeable when working through low-level upgrades. Now, you can hoard Spare Parts and rush through multiple upgrades right before you dive into battle.
UPGRADING WITH GOLD
Finally, even with Spare Parts in the picture, you can still use Gold for instant upgrades. If you run out of Spare Parts and don't want to wait for the Workshop to produce more, you can buy them with Gold right on the spot.
