how about you can pack a punch your gun multiple times but each time you buy, it increases the price by 5000 points. everyone knows that even after you pack a punch a gun the zombies get hard to kill in the later rounds.
for a map (assuming it wont follow the four characters we all know and love) what if there was something like a haunted forest with random shacks hidden in it. each shack contains a perk machine and a gun. then a graveyard located in a random spot in the forest with the pack a punch machine located here and with all the developers name on the tombstones. and just for kicks, put in frankenstein or something as a 'camp counselor.'
More A7x!!!!! anything with a sick rock solo like 115. Need Pack-A-Punch special grenades. like pap gerch device that has a huge radius and sucks zombies through walls or somethings.Pack-A-Punch perks once.ONLY ONCE. For guns pack-a-punch them again for another 5 grand for full ammo or something not to big cause you could be a wicked overkill with a thundergun and a hk you could keep buying ammo for. Don't stray to far from the original game mode and cool new game modes. Same characters in the games storyline. Like call of the dead where theres new characters but the old ones are still in the game. Hope this gets read but i dout it. Anyway Zombies Forever!!
What I would like to see in BO 2 Zombies is the ability to pause during multiplayer. It's very annoying to get a crawler at the end of a round so that someone can use the restroom or something. So this could work by pressing start, and there would be an option that says "Vote to Pause". Something pops up at the top of your screen asking the players to pause. Start for yes and Select for no. When the players are ready to resume, there will be 4 check boxes (4 players for example). Everyone has to press Start and the game will resume.
Another helpful idea would be to Save and Exit games to continue later. This can be the same as the "Vote to Pause" option. You will see it when you press Start.
I would also enjoy Solo Leaderboards and the ability to see your total number of zombie kills in your carrer.
