Background Story

Everyone has a knife in their house.

Knives are used for so many things — opening your packages, cutting meat, accidentally wounding yourself, and more! They're just so versatile. So, when the apocalypse came along, many reached for their simple knives. Sure, perhaps they aren't as great as an Axe for dealing damage, but knives are light, easy to use, fun to swing around, and useful for incapacitating those brain-dead infected for a bit.

R-Brain Hardwork decided to do some research into the logistics of creating a knife with an optimal balance between force and being lightweight and found that it was quite difficult to find this perfect balance. With small knives, there was too little room for modifications. They eventually settled on just making it as high-quality as possible and telling their buyers to go a sort of "Rambo" while using it. This just meant swinging it as hard as they could.


  • Throwing is a unique ability to the Rambo Knife.
    • If it lands, it deals 50% more damage. 82.5 points from 55.
    • After you throw it, it will take 3 seconds to come back.
      • You are entirely defenceless, so switch to a gun.
      • Others will still see the knife, but it'll be missing for you.
    • This throw is affected by gravity, much akin to a Brute's club.
    • If you hug a wall, your throw will go right through.
  • Unlike R2D 2014, this cannot save you from a Leaper or a Stalker.
    • However, you can cut an Edgar's tongue to protect yourself, so long you aren't pinned.
  • Fighting a Ticker isn't recommended. You'll lose a lot of your HP.
  • Once you melee a mob, hold down your mouse.
    • While they're down, you can throw a knife onto their back.
      • This saves time and it's just easier to land the throw.
    • In Team Deathmatch, this can lead to a clean execution.
  • Try to learn to switch weapons on the fly. It will be helpful.
    • If a mob gets too close, this is your security.
  • You can throw this to open doors that require a humanoid touch.
    • For example, Zero Kelvin Station's keypad doors. By throwing it at the keypad, the door will open for you. This trick can also be used in Quests.
  • Like other melee weapons, Boosters can be extremely useful.
  • Combined with an accurate weapon, this might make a lethal combo towards a Normal Zombie. It allows time to deliver a headshot before they can react.
  • Throwing this won't counter a brute's club.
  • In Melee Smash, this can be very effective, as you can use it at long range.
  • The animations now synergize into a 3-hit combo.
    • A fourth one can be seen if you jump and click in mid-air.



  • Throwing added in v0.9.1.
  • New animations added in v0.9.1.
  • Energy changed from 6 to 5 in v0.9.0.

  • This is the first returning melee weapon from R2D 2014.
    • The former animations were the same as R2D 2014.
      • In R2D 2014 there was a knife throwing jump glitch what made you jump very high if you did the throwing correctly.
    • In old R2D, a thrown knife could 1 shot a zombie but today, it can't.
  • In Debug, this used to cost 32,000$ and dealt 35 damage to mobs.
  • There is an uncommon glitch where you can throw two knives at once.
    • However, this glitch became extremely difficult to perform as a side effect of some Karambit patches.
  • In Team Deathmatch, a thrown Rambo Knife used to be able to damage your own teammates.
    • Killing them would still net you the experience and money.
  • Breezy was the first fan-made skin made specifically for R2DA.
    • This holds the record of the most skins for a weapon.
  • When you equip the Rambo Knife it has the CS:GO bayonet animation.
  • The mesh can be found in the ROBLOX catalog under Bombo's Survival Knife.
