I think the lighthouse island is a given, I would be shocked if that section wasn’t turned into a survival map.
I personally think it’d be a bit of a goof to make ONLY the bridge where deadshot is a survival map, would definitely be a fun change of pace for survival since it’d be very challenge map esque.
I also wouldn’t mind seeing the boss fight arena made into a survival map like how we saw mars for Astra. I honestly think that should just be a trend for every map where that’s applicable. Bonus points if treyarch spices it up and implements attacks from Dravakar (sparingly) just to, once again, give some change of pace to these survival maps.
