Learn how to unlock the Syndicate Gun in Battlefield Hardline's Betrayal DLC. This guide details the cooperative steps, map locations, and weapon requirements.

Walkthrough
  1. 1
    Ensure five players with the Betrayal DLC are in a party, using party chat.
  2. 2
    Each player must equip a different classic weapon: M1A1 Thompson SMG, M1 Carbine, 1887 shotgun, M1903 sniper rifle, and the Mammoth Gun.
  3. 3
    Join a server running the Cemetery map.
  4. 4
    Meet at the large circular catacombs area north-east of the map's center (the "D" flag in Conquest Large).
  5. 5
    Identify the four mausoleums around the circle with doors bearing Syndicate emblems (circular maze motif around a Greek letter).
  6. 6
    The first four players must stand in front of the doors corresponding to their weapon and the Greek letter as follows:
    • South-East: Phi (M1A1 Thompson)
  7. 7
    South-West: Xi* (M1 Carbine)
  8. 8
    North-West: Pi (1887 Shotgun)
  9. 9
    North-East: Sigma (M1903 Sniper Rifle)
  10. 10
    The fifth player, equipped with the Mammoth Gun, must go underground to the west side of the circular room. They need to stand on the octagonal plate marked with a mammoth's head, in front of the golden doors (marked with two Sigma symbols).
  11. 11
    The four players at the doors must simultaneously interact with their respective doors when prompted.
  12. 12
    If successful, a lightning bolt will strike the central tree, causing it to catch fire, and the golden doors downstairs will open.
  13. 13
    Descend the spiral staircase to the crypt to find the Syndicate Gun on a sarcophagus.
  14. 14
    Collect the gun. Note that only one player can collect it per round, requiring the process to be repeated for other group members. Exit the crypt promptly after collection, as the doors will close.
Tips
  • The Syndicate Gun functions like a battle rifle, offering lower recoil and a larger 47-round magazine compared to other battle rifles.
  • It shares the same "long-range" damage profile as the FAL and HCAR, achieving a three-hit kill up to 46 meters and a four-hit kill beyond that.
  • Its fire rate is slower at 550 RPM, but its large magazine and reduced vertical recoil make it manageable.
  • While it has good stationary aimed accuracy, its high SIPS (Spread Increase Per Shot) value means sustained fire will quickly reduce accuracy.
  • The unlock requires cooperative effort and communication among five players with the Betrayal DLC.
  • The specific Greek letters on the doors are Phi, Xi (serifed version rotated 90°), Pi, and Sigma.
  • The fifth player must be positioned on the mammoth head symbol on the floor in the crypt.
