Kosma, did you see Javelin glitch response?
In case you didn't:
Take a create a class slot.
Layout:
Preferred:
Perk1: Marathon
Perk 2: Danger Close
Perk 3: Anything.
Primary Weapon: whatever
Secondary weapon: any launcher besides thumper (javelin is most widely used)
primary equipment: semtex grenade
secondary: anything.
Basically, you swap to your launcher. From there you hit and hold R1/Right Button like you are cooking said semtex grenade. Then, while still holding R1/Right Button, hit Y/Triangle to swap back to the launcher. From there, once you are shot, your launcher goes off, and with danger close as a perk, pretty much anyone in the room u die in that is an enemy dies. *
*If you climb a ladder or wall, this gets canceled out.
People do this alot in HQ.
