Ending and Menu are the only two SFX that are currently unchanged from their Containment Breach counterparts where as the Omega Warhead and Alarm 2 have had the most alternatives and changes throughout their lifetimes.
Menu [Remastered] was originally going to be kept as Menu from the original Containment Breach however players loved this piece, and as a result it has remained the main theme of SCP: Breached Containment
The Omega Warhead uses it's sirens and Alarms from Containment Breach, and it's music is a remix by Nukee and announced by C.A.S.S.I.E totaling 3 sources to create it's iconic Detonation Sequence
SCP-049's Chamber Area was originally never going to happen with it's original concept having Facility wide ambience labeled The Dread, Heavy Containment and Entrance Zone and would change as the round progressed but was scrapped and changed into SCP-049's iconic blackout based on SCP - Containment Breach.
