Would you be willing to answer a few brief questions about PlayStation Forums?
The reason you got the assist was because the other guy got the last bullet required for the kill.
Aim better and shoot to the head. D:
I got 18 assists once..I threw my controller at the wall...
Assist cash should be relative to how much damage you dealt to the enemy. So, if you shoot the enemy until he's lost 75% health, and a teammate finishes him off, you should get $75 for the assist.
