This is a guide for all 9 of the secret achievements available at the moment in rust. If you find the guide helpful, please consider leaving a like and a good rating, thanks!

Notes:

• This is my first proper guide, so any feedback would be great!
  
  
• There are 2 DLC ones, however you can still get them even if you don't have the DLC, you can get the items from other players or some modded servers even give everyone the blueprints.
  
  
• They are rated easy, medium and hard based on how difficult they are and how long they take.[/list
  All of the achievements and their descriptions:
  
  
  • Sealbreaker: Completely fill your hydration bar
    
  • Glutton: Complete fill your food bar
    
  • Giddy Up!: Ride a horse for 1km
    
  • Save the Planet: Recycle an empty can at a recycler
    
  • I'm the Captain Now: Reach the bridge of the cargo ship
    
  • Something of a Scientist Myself: Kill 5 scientists
    
  • On the Deck: Land a minicopter on an oil rig helipad
    
  • Getting the Band Together: Join a team of at least 4 people where everyone has instruments equipped
    
  • Sunglasses at Night: Equip a pair of sunglasses after the sun goes down

To unlock this achievement, you must fully replenish your hydration bar (Middle blue bar with cup icon) to 250




Method 1
An easy way to do this would be to find other players' water catchers or barrels, they look like this:



Small Water Catcher



Large Water Catcher



Water Barrel

Interact with them by pressing E and click the cup icon to drink it.

Method 2
A slightly harder way to get this achievement is by finding water bottles or jugs, they look like this:


They can be found in a lot of places, but usually these crates:


Ration Box

Food Crate

Once you obtain the water bottle or jug, simply equip it and left click.

To unlock this achievement, you must fully replenish your food bar (Bottom orange bar with knife and fork icon) to 500



Method 1
Quite an easy way to complete this achievement would be to forage food from the ground, this can be but is not limited to: mushrooms, pumpkins, corn, blueberries (as shown below)



Heres a table for their stats:


These foods are quite common to come across, so it won't take too long to reach 500 food points.

Method 2

Once again, a quicker method would be to loot the crates:

Ration Box

Food Crate

These can provide a range of foods such as:


Granola Bar

Chocolate Bar

Can Of Beans

Can Of Tuna

Apple

Pickles


Method 3

Finally, the hardest method would be to kill live animals and harvest their meat, cook it and eat it.

There are currently 7 types of animals in rust (including humans), all of which produce meat when harvested, they are:

• Bear
  
• Boar
  
• Chicken
  
• Deer
  
• Horse
  
• Wolf
  
• Human

To unlock this achievement, you must ride a horse for 1km (1000 metres).

Method 1

The free, but time-consuming method to obtaining a horse, is to look around for one. They are usually found in forest areas.
The expensive but quick method to obtaining a horse would be to claim one from a The Ranch or Large Barn. To claim a horse you need a saddle, which costs 75 scrap.

Tip: Pick a horse with a high speed (around 50 is best), although this can be increased with horseshoes.

Jfarr created a decent video about horses: https://youtu.be/UDPe5IJOYjw

To complete this achievement, you must recycle 5 empty cans in a recycler.

To obtain empty cans you must find 5 cans of beans or cans of tuna and consume them.

Can Of Beans

Empty Can Of Beans

Can Of Tuna

Empty Tuna Can

Once you have an empty can, go to a recycler, they look like this:



and can be found at these monuments:

• Satellite Dish
  
• Lighthouse
  
• Train Yard
  
• Water Treatment
  
• Power Plant
  
• Mining Outpost
  
• Harbor
  
• Launch Site
  
• Abandoned Supermarket
  
• Oxum's Gas Station
  
• Junkyard
  
• Military Tunnels
  
• Outpost
  
• Bandit Camp

Now you have found a recycler, interact with it, place your 5 cans inside and turn it on.

Heres an old video guide of the location of recyclers: https://www.youtube.com/watch?v=9YWW6YOWhR8

To earn this achievement, you must kill 5 scientists, they look like this:



and can be found in many places. They can be found next to broken down vehicles next to roads, or in monuments such as:

• Cargo Ship
  
• Train Yard
  
• Large Excavator Pit
  
• Launch Site
  
• Military Tunnels

They are quite easy to kill from a distance, as they have a range in which they can detect players. A prim* could wipe out a scientist, although it might take a lot of ammo and time.

*prim: a primitive player, usually still using stone tools and a bow

There is a good Reddit post about this here: https://www.reddit.com/r/playrust/comments/aztjfx/best_way_to_kill_scientists/

To unlock this achievement, you must land a minicopter on the helipad on an oil rig. I think transport helicopters work too, but I'm not sure and minicopters are cheaper anyway.

How to get a minicopter

To get a minicopter, you can either steal one off of someone although this is very rare, or you can buy one from Bandit Town. They cost 750 scrap and spawn with 100 Low Grade fuel in the fuel storage. You might want to bring more fuel as 100 will most likely not be enough to get you there from Bandit Town. Landing on the helipad might be quite hard as the scientists will shoot at you.

To complete this achievement, you must reach the bridge of the cargo ship.

Tip: The cargo ship isn't always on the map, it is a temporary monument

Firstly, you will need to prepare for the cargo ship, as it has a lot of scientists on it and you will need to eliminate them. Good weapons to consider taking with you are:

• MP5A4
  
• Custom SMG // edit: this isn't recommended, as stated in a comment
  
• Assault Rifle
  
• LR-300 Assault Rifle

Also bring lots of ammo and medical supplies as you will need to shoot a lot and heal from being shot.

How to enter cargo ship

To enter the cargo ship monument, you will need to approach it in one of the following:

• Minicopter
  
• Transport Helicopter
  
• R.H.I.B Boat
  
• Motorboat

You can also swim, but it is not recommended. Once you are on board, kill all the scientists and find your way to the bridge (the main room at the top I think)
