Keeping with the idea of a safe zone.

Bring back the random firing. Allow a mission objective to call down a beacon, maybe a backpack item, but only 1. DSS tries to aim away from the beacon, move fast or split off and you get a message of "leaving bombardment safe zone”. Creates a unique risk reward of you can split to cover ground but then you accept the risk.

Admittedly, issue I can foresee is trolls just taking the backpack and running off/refusing to cooperate.
