Im looking for a map I played a long time ago

Im looking for a map that I played a LOOOOOOONNNNNNNNNGGGGGGG time ago! it was Infection, It started out with survivors on The beach across from the Island with weapons and machine guns, they had to hold out until a Friendly Falcon arrives and takes the to “The Rock” which has a base on it with shade turrets and a Gauss Hog, the zombies then get access to Banshees’ and start attacking the base, I forgot the name but it was reallllllllly fun, If you know the name of the map please link me to the file share!!
