Everyone knows the classic zombie Power-ups: 'Max Ammo', 'Insta-kill' and 'Nuke', but how about making available, in the new rumoured 4v4 zombie mode, 'Power-down' zombie drops - which solely affect the opposing team when a team-mate acquires them.
Dead-head - Zombies may only be hurt by damage to the head for 30 seconds by the enemy team.
Slashed Ammo - Removes half of the opposing team's ammunition and equipment.
Juke - Zombies will only be drawn to and attack the opposing team for 30 seconds.
- Double Points counterpart:
Halved Points - Opposing team will only gain half the amount of points they normally would for any action for 30 seconds.
Demolisher - All boards that have been placed throughout the game by the opposing team are instantly removed.
No Sale - Opposing team may not purchase anything for 40 seconds.
- Death Machine counterpart:
Tommy Gun - Entire opposing team is armed with only a standard Thompson for 30 seconds.
- Random Perk Bottle counterpart:
Poison Bottle - Each member of the opposing team loses a random perk.
I don't think a counterpart to 'Bonfire Sale' should be available because I think it was only a one-off power-up from Five, and only Five.
Rather than a golden, glowing hue, give the 'Power-downs' a bright, black sheen with slight red sections.
[Sorry to adjust the list for you mate, but I just thought I'd help by neatening up the thread and adjusting some of your ideas. The premise is brilliant, and an idea like this really shouldn't go to waste. If you'd like, use what I've done here as your own ideas - you have entirely full credit. Maintain this thread!]
