"Survival Of The Fittest" is a Survival Challenge present in 60 Seconds! Reatomized
General Information[]
Survival Of The Fittest is often considered by the community as the hardest Survival challenge in the 60 Seconds! Reatomized. This can be explained by the fact that it requires extreme luck.
In this challenge, you will be in the shelter several weeks after the explosion (30 days to be precise) and your resource are diminushing. But you managed to caught a message about a cache full of food and water from your radio before it broke. You will therefore have to make multiple expeditions to finally find it.

Challenge Texts[]
At The Begining:[]
- After weeks down here, it's not looking good for us in terms of supplies. But there's hope - we learned on the radio there's a hidden supply cache neraby. Hopefully, the transmition gave us enough to go by and we can locate it before the radioactivity out there makes us grow extra pair of... anything. | Enough sitting around aimlessy, waiting to be rescued. Everyone, get ready to do some exploring!
After the 1st Expedition:[]
- Our expedition found no signs of any supply cache mentioned on the radio. Maybe our next trip will be more lucky.
After the 2nd Expedition:[]
- The expedition was a disappoinment when it came to uncovering any details about the hidden supply cache. We didn't manage to find any of the landmarks mentioned in the radio broadcast, and still have no idea where to look.
After the 3rd Expedition:[]
- The expedition finally brought some information about the supply cache! We've pinpointed one of the landmarks from the radio message. At least now we know wich direction to head next time.
After the 4th Expedition:[]
- We followed the directions from the radio broadcast, and continued on our previous path. We haven't found other signs just yet, but we're optimistic about future expeditions.
After the 5th Expedition:[]
- According to the radio broadcast, the supply cache is hidden somewhere close to the next landmark. We've located most of them already, so finding the last one shouldn't be too difficult. We just have to keep going out of there.
After the 6th Expedition:[]
- Our expedition pinpointed the final landmark. We're so close to the cache, we can almost taste the soup already! We need to go out there once more, to finally unearth the stockpile.
After the 7th Expedition (End):[]
- Our mission was a total success! The hidden cache was full of supplies, we could basically build a soup can fort. Come to think of it, we just might. Who's going to stop us?! Maybe we'll even set up shop and trade the cans for other supplies. Like a gramophone. We really missed those. Either way, we will never starve again! (Challenge Completed)

Here's how I got the win. Five times I have completed this challenge. Let me know if you need help completing.
Scavenge Pattern:
- Load the Game until the checkers board appears. There undergoes three cycles of items. The cards, the harmonica, and the checkers. The Checkers board is the best path to victory.
- Send Mary Jane out with Checker Board. Note that Mary Jane always comes back around day 36-39.
- Then, Send Dolores out with Gas Mask.
- If you have the gas mask, send Timmy out. If not, send Ted out.
- Send the family member you have not sent out. (If you have gas mask, send with it. If not, send them out with checker board, or if you don't have that, cards)
- Try to heal family members. If you can, heal Mary Jane and send her out again.
- Send Dolores out again.
- Ted/Timmy out too.
Tips:
- Scavenge when presented opportunity, unless available family members are crazy/sick and you don't have mutant protection.
- If you don't have a gas mask, and you have spare water, trade for water chip. He might give you his gas mask.
- Never answer door for anyone or raid neighbors. Otherwise, raiders might come. Try to trade for items you need, and never trade gas mask.
- Do not send a crazy family member out. They will die, unless you have the safety of the mutants you gave food/water to.
- If you have the mutant friends protection for expeditions, sick people are good to go out. If you don't have any, just send any person out other than Ted, as he is most likely to survive expeditions. That means no gas mask! Radiation sickness isn't going to affect sick people.
- You can give water to Doctors.
- Feed/Hydrate everyone day 34, 39, 44, 49, and so on.
- Trade for Gun, Bug Spray, or Boy Scout Handbook, unless you are trading a medkit and someone else needs it. This helps prevent roach sickness from spreading in shelter.
IMPORTANT: If the raiders come, do not give up, This is a result of pure unluckiness. Try again. You can do this.

One of the strategies that I used to win in this challenge.
- Scavenge Pattern:
- For your 1st expedition send someone with: Suitcase ; Gas Mask ; Checkerboard/Deck of Cards/Harmonica(Depending on what you have).
- For your other expeditions, send someone depending on what you need: In your game you'll need in priority: Boy Scout Handbook ; Rifle ; Bug Spray ; Ammo ; Radio. So take something which can help you to bring back one of those Items. If you always have Suitcase try to send your other expeditions without for saving it for the last expedition. If you have enough items, take something for bring back more soup or water. If you haven't anything for that, send with the Gas Mask.
- For the last expedition send someone with: Suitcase ; Gas Mask ; Boy Scout Handbook/Map/Flashlight/Soup/Water ; Axe/Rifle(If Raiders are around the shelter). If you haven't Suitcase or Gas Mask, just take one of the last items.
The Boy Scout Handbook, Rifle, Bug Spray will be useful for kill the mutant roaches and not get sick. The Ammo and Bug Spray will be useful for the shower event if you haven't Gas Mask in your shelter, it can help you to cure everyone's sickness if you use something, but if you have nothing, everyone will get sick and you probably don't want that. The Radio will be useful for "Silent as the grave" event where everyone get tired if you haven't the Radio.
For the characters try to send everytime someone in good shape for the expedtion. If you don't have anyone in good shape try to send someone with: Boy Scout Handbook/Map/Flashlight/Soup/Water. It will increase chances of coming back. Also try to keep everybody alive, the more you can send, the better it will be.
If you're already followed by the Raiders in the 2nd or 3rd expedition, it will be very hard for the rest of the challenge, so you can continue the game or instead restart already.
