I've been thinking and I've come up with a few ideas for what Black Ops 2 Zombies could have:
-Quick Revive+ - Revive teammates 5 times faster (Normal QR = 3 times faster).
-Juggernog+ - Take 14 hits from a zombie (Normal Juggernog only takes 7 hits).
-Speed Cola+ - Reload your gun 5 times faster (Normal SC does it 3 times faster).
-Double Tap+ - Fire your weapon 4 times faster (Normal DT does it 2 times faster.)
-Stamin-Up+ - Run for 3 times longer than normal (Normal SU does it 2 times longer).
-PHD Flopper+ - Drop a bigger nuke when Dolphin Diving.
- Deadshot+ - No change
-Mule Kick+ - Lets you have 4 guns (Normal MK lets you have 3 guns).
-Caffiene Kick - Makes you aim down the sights of your gun faster. Also makes you go back down to hip firing more quickly (Cost: 2000p)
-Morphene Hit - Makes your weapon useful for a change. Shoot your downed teammates to revive them. (Cost: 3000p)
-Cheap Vodka - Allows you to open doors, buy guns, use the box etc for half the price. (Cost: 4000p)
-Helium Pump - Makes you jump 3 times higher than normal. (Cost: 2500p)
Let me know what you think about it in the comments!
