It is 11 it is either attack dogs or a gunship
i belive so! and they have black ops for the ds?
You get a Radar by getting a 3 kill Killstreak
you get the required amount of kills
Yes anything that you don't call a care package for adds to your killstreak
The best killstreak is the Tactical Nuke but use killstreaks that you can get frequently.
Call of Duty 4: 7 kill streak: Attack Helicopter Call of Duty World at War: 7 Kill streak: Attack dogs Call of Duty Modern Warfare 2: 25 kill streak: Tactical Nuke Call of Duty Black Ops: 11 kill streak: Gunship or attack dogs.
There is no highest
everything that comes with the hardened edition, plus your own RC suicide car. This will be a killstreak in the game.
Well, in CoD4 killstreak rewards end with a helicopter after 7 kills. The highest scored by a person ever, I do not know. It is hard to tell as many players glitch, hack or cheat the game and therefore you cannot use their numbers as a basis for information. My highest killstreak is 27, and it stopped there because the game ended. I was 27-0 with the potential to keep going, so it is tough to say what the highest killstreaks are. But there are people with 40-50 killstreaks.
It is a Perk used to gain a killstreak with one less kill. Very use full if you choke under pressure to get your killstreak. Hardline Pro gives access to change the care package drop to another random thing.
NUKE!!!
There is no gattling gun perk in Call of Duty: Black Ops. The only gattling guns that you can control are: Airdroppable sentry gun at a 6 killstreak (without hardline) Chopper gunner gattling gun at 9 killstreak (without hardline) Death Machine: a gattling gun you can walk around with, randomly acquired from a care package. Ammo is limited. Hope this helped.
