What is Fast Comeback?
It is something you earn during Wasteland King when you kill your troops. Your training speed up is increased by 300%, and you can craft 120% of the troops killed at this speed. This is the BEST way to train troops, to grow your account faster!
The more troops you kill, the more fast comeback you earn. You want to make sure not to earn more than you can complete, so if you are low on RSS or Speed Ups, be careful what you kill!
If you know a bit about Fast Comeback, and are ready to get started, we developed a tool to make it easy. The Fast Comeback tool helps you calculate what speed ups and resources you will need, as well as calculates how many troops you will need to kill to earn a certain amount of Fast Comeback.
PREP FOR earnING Fast comeback

Step 1: Make sure to have enough Infirmary and bootcamp buildings
You will want to have 10 infirmaries and 10 bootcamp buildings. This is the maximum amount you can have. You will want to work on upgrading them to the highest level you can. This will assist you in earning more fast comeback, as you will have a larger deep healing to fill, and you will also be able to train more troops, faster (which means savings on speed ups)!
Step 2: fill your infirmary with taxi’s
You do this because taxi’s (T1 Vehicles) are cheap to heal in the infirmary, compared to troops. All healing in the infirmary takes resources to heal, and so if all your troops get sent here, you will have a high rss bill to pay to heal them. Instead, once your infirmary is full, your troops will be sent to your Deep Healing Center. It has the same capacity as your infirmary.
Filling your infirmary is a CRITICAL step. If it is not full, when you kill your troops, only a % of them will count as “killed” instead of “injured, meaning you will earn LESS fast comeback. When your infirmary is full, and everything is being sent to deep heal, 100% of the march counts towards fast comeback.
To kill your taxi’s, either put them on a tile, and ask someone to attack it, or ask someone in your state to set up a ‘Taxi Killing Station’, where they will put troops on a tile, and you can send your taxi’s to die.
Deep healing does not heal troops by using resources. Instead, you can either heal them with deep healing potions (preferably) or with diamonds (not preferred). Earning deep heal potions is a waiting game and the rate improves once you keep your normal infirmary empty afterwards. You earn them for free, and can use them gradually as you earn them to get your troops back for free. If you choose to heal with Diamonds, wait and do so during Valiant Conquest weekend, when the Diamond Spend event is ongoing so you earn rewards for spending diamonds to heal your troops.

To Do On Wasteland KING: Earning Fast ComebacK
Step 1: Kill your troops on enemy towers
When your state is occupying its own hub, you have to travel to another region to attack their towers. If your home state is taken over, you can earn your fast comeback on your home state towers. Make sure to follow the set out NAP guidelines for that day when going to attack other regions. You do NOT need to leave the alliance to earn fast comeback. You will want to keep an eye on how much fast comeback you earn. You can do this by looking in wasteland king > Personal Reward > second (i) button at bottom of the screen. If you need tips on how much fast comeback you can afford to have, use the Fast Comeback tool to help calculate that for you.
Note: if you are defending in a tower during Wasteland King, enemy attacks will also kill some of your troops, and you will earn fast comeback this way too!

You will want to keep an eye on your deep healing numbers as well. If you exceed deep healing, you will then send troops to Alliance Infirmary. This is not good if you left the your home alliance to join the state alliance for the day, as it means you will be stuck there until you finish healing alliance infirmary, which requires alliances coins for healing (or you will lose all those troops permanently).

Some rough estimates:
Killing T9’s – to earn 10M fast comeback, you need to kill 185k of your T9 troops
Killing T10’s – to earn 10M fast comeback, kill 140k T10 troops
Killing t11’s – to earn 10M fast comeback, kill 104k T11 troops
Again – only earn as much fast comeback you can afford to train troops (you will need RSS’s and speed ups)
Step 2: Wait for the governor to activate the fast comeback boosts, and start training!
The governor will activate this at reset end of Saturday into Sunday. Do not start training troops until you see this boost activated! You will get a notification in your system messages.
It is also great to pair this with your own training speed boosts and the talent skill Cost Reduction.
The fast comeback is the ONLY boost that is activated if your tech hub is conquered by another state. It will begin automatically once the other state has secured your hub by occupying for 8 consecutive hours, or at the conclusion of the Wasteland King event.
Don’t train until the Ace Commander event on Sunday so you earn points for that too!
Other Important thinGs to consider
- It should be known, you will need a lot of taxi’s in reserve to fill your infirmary. And you will also need troops you are willing to kill, to go into your deep heal. it can take weeks to get your troops out of deep heal, when you go the potion route instead of diamonds.
- You need enough rss and speed ups saved in order to use up the fast come back limit you’ve earned. This can be tough if you haven’t spent 2 weeks prepping.
- Don’t forget to use talents when you want to heal your infirmary. Use fast heal and then wait til reset to use cost red for the retraining and healing.
- You will have 3 days to complete your Fast Comeback. You should aim to train on Sunday as it is the Ace Training day, and on Tuesday, when it is the Training speed up day during Off week.
- When doing fast comeback, not ALL of your troops go to infirmary/deep healing. There is a certain % that permanently dies. That’s why you want to make sure to only earn as much fast comeback as you can afford to craft. 30% permanently die if you have no research/nova at all; about 10% permanently die if you maxed out survival in research/nova. This is why you only want to get enough fast comeback that you can afford to retrain – because you do lose some troops permanently, but you can recraft them + more for cheaper
