Call of Duty: Modern Warfare 2

Think about the name. I'm guessing you have to steal a guys gun then kill someone with it.
Most of these have to do with accolades I think. Or something like that

When someone on your team calls in a supply drop you steal it several times. I don't know if it works for the other team's supply drop i only stole from my own team.

You can steal the enemies aswell as your teammates supply drops i got it in like the first 3 matches i played

Steal an enemy supply crate either 5 or 10 times.

Steal the enemy's supply crate a few times and you should unlock the title

I got kleptomaniac from completing the challenge renaisance (kill 3 people with 3 diferent guns in one life)

I got it by stabbing an enemy who was in last stand (that was the thing i did that round to unlock it that made the most sense to me)

im pretty sure it has something to do with scavenger, because i unlocked the Klepto title after upgrading it to pro

5 enemy care packages sounds like it should be true, but like X_eternal_X I got it from killing 3 people with 3 different weapons in 1 life.. odd. O.o

Steal supply crates.

I got this from killing someone, Stealing thier weapon and then killing them again with it.

I am VERY sure that I havent ever stolen more than 1 supply crate on a map and I have it.

Same as Manicblitz, I've got it and I've only ever used a supply crate once

It is entirely possible that you can get this emblem from stealing supply crates AND/OR from stealing a gun and killing someone with it

I looked it up in multiple locations and all say the same thing. In order to get the kleptomaniac title you steal or "hijack" like 5 -10 enemy crates. its not hard to do just run core and try to stay near the enemy .... i got it fairly easy but then i'm really good at staying hidden.

I have klepto and i stole zero crates (my team mates or the enemy)...
I got it cos i ran outta ammo and picked up a dead enemy gun and proceeded to nail 3 ppl with it.

I got Klepomaniack by killig thre people with diffrent guns Whithought Death
