Complex Map - Shotgun

Probably been asked before but what is the rule and timing of when the shotgun spawns on Complex in Big Team Battle.

I believe it is a Random Ordnance however I am not entirely sure. If so, it will drop randomly once in the game. I don’t believe it is on a Initial Spawn timer.

If you have played the matchmaking version of Complex recently, download it off the temporary history and look at the Ordnance drop in forge. That way you will know whether it is a Random or Initial Ordnance + the timing for each drop if the latter.
