Wreckages are crucial to the progression of the game. They are currently the only source of blueprints and potatoes. There are currently 3 wreckage variants in the game, each with increasing rarity. Here is some general information about all three structures:

• They all emit a distress signal, which can be detected from a maximum of 200 meters away.
  
• Breaking the radio disables the distress signal beacon, meaning you will no longer detect it.
  
• They all contain metal platforms that can be destroyed for scrap
  
• They all have at least one blueprint monitor and one package
  
• Not only will the monitors yield a new blueprint, but they can broken for materials just like the distress radio.

No blueprints are exclusive to any one structure. Items are unlocked in a pre-defined internal order, so it doesn't actually matter what specific monitor you hack for a blueprint

These are the most common structures currently. They contain:

• 2 Blueprint monitors
  
• 2 Packages
  
• The distress radio and both monitors, which can all be broken for 3 metal scrap and 7 electronic total
  
• 17 Metal floors which can be removed for 21 total metal scrap

Trivia:

• This is incredibly easy to notice, due to the tall bright walls forming the hallway
  
• One of the floors cannot be destroyed

These are much rarer than the hallway wreckages. They contain:

• 1 Blueprint monitor
  
• 1 Package
  
• The distress radio and monitor, which can both be broken for 2 metal scrap and 4 electronic total
  
• 7 metal floors which can be removed for 8 total metal scrap

Trivia:

• This wreckage will automatically spawn near you if you lose your crowbar.
  
• Despite appearing quite intricate, the main structure cannot be entered (There is a rectangular room in the lower part of the asteroid which contains the blueprint monitor and package)
  
• The left exterior wall of the lower room features a crowbar you can grab
  
• The entrance is obstructed and cannot be entered without removing some of the metal floors
  
• Unlike the other two wreckages, which have orange-accented metal floors, This wreckage features blue-accented ones.

These are the least rewarding structures in the game currently. They contain:

• 1 Blueprint monitor
  
• 1 Package
  
• The distress radio and monitor, which can both be broken for 2 metal scrap and 4 electronic total
  
• 5 Metal floors which can be removed for 8 total metal scrap (there is one panel at the bottom of the asteroid formation)

Trivia:

• These structures are very hard to spot, which may contribute to the illusion of rarity

These are the rarest structures in the game currently. They contain:

• 1 Blueprint monitor, which can be broken for 1 metal scrap and 2 electronics
  
• 1 Package
  
• 10 Metal floors which can be removed for 18 total metal scrap

Trivia:

• This structure only spawns in the Dense Obliteration biome. You can see what biome you're in using the F3 menu in-game.
  
• This structure does not emit a signal, meaning you must look very closely to find it.
  
• These two facts contribute to what makes it the rarest structure in the game.
