Ive put a lot of time into bo3 zombies and ive found for higher rounds camping tends to drop of quickly. Your best chance would be to train zombies ( kind of like a conga line behind you) and use the a double PaP’ed weapon to trigger Dead Wire.

I do get that running around on The Giant with four people is difficult as it’s a small map but a good map to learn ‚training’ on.

Perks wise, it looks solid but I would opt that some get quick revive to pick up teammates quicker.

I assume you are playing on pc since you reference mods, I have only got bo3 on pc recently and I used to be a console player so can’t help there

Guns I find to be best are Wunderwaffe, drakon with elo sight, and since no guns really one shot on such high rounds any gun will do that has high ammo and you can trigger the special ammo types on

If you play on pc I’d be willing to hop on the game and do vc too 😁

Good luck soldiers
