level 4
15
Go up levels
there's a certain amount of levels that you have to get to to unlock a certain amount of killstreaks
Killstreaks in MW2 are tools, such as Predator Missiles, that can help you eliminate your enemies easily. If you have a Killstreak but you are killed, you will have to start the streak again but you will keep any killstreaks unlocked.
Yup. You must become dirty at the game like pistolpete917!!!!!!!!!!!
you can not get a nuke in a care package. the rest of the killstreaks can be found in a care package tho
well it is on certain ranks, im not too fully sure what are those ranks but if you go to your killstreak then it will tell you how many levels you need to unlock a new kill streak
When you level up to level 10 you unlock kill streaks and have the option of unlocking one of the many available. From there on every 4 or 5 levels you can unlock another one.
get to level 48 and you unlock the ACR
no
Go to "callsign & Killstreaks" then select "Clan Tag" here you can create a custom name.
your sights go out, killstreaks including the nuke deactivate, equipment don't work it's pretty awsome
