Survival Mode overhaul and survival map variants.

The survival (or zombie mode) has remained unchanged for YEARS. A change is needed to make it more interesting.

First off, new zombie variants.

Firefighter zombies: Starting from wave 11+, firefighter zombies have the same health as normal zombies, however they carry incendiary grenades, throwing them at players / vehicles once in a reasonable throwing range. (potentially even flamethrowers). This adds more difficulty to the game as flame damage reduces half of your health. Players won't be safe in spots where zombies typically cannot reach (e.g slightly raising that one elevator on the City map)

Police Zombies: Starting at wave 7+, Police zombies are 1.5x faster than zombies and have the same health as standard zombies. Their gameplay is to simply charge at players and potentially catch them off guard.

Game events:

Starting wave 15+, the BRAF gets involved as a hostile force. Jets will fly overhead and drop bombs over the play area. Their bombs can kill both zombies AND players. Their arrival can be detected audibly with the sound of distant jet engines.

Bricksville zombie map variant:

Bricksville will also get a survival mode, along with a special variant of map. Buildings will be toppled over (see one of the attachments), with an overall feeling of abandonment, such as half damaged buildings with caved in roofs. The airport will be fully destroyed, with large smoke plumes rising into the air.
