Re: Multikill mission?

I am having the same issue as you.  No matter what type of explosive multi-kill I get, it would never give me the task completed.  Then last night while playing, a friend of mine was able to complete it.  He advised that he had to kill 3 people at once in order to get it. Now it would seem to me that a multi-kill should be 2 or more at once, but apparently you need to kill at least 3 people at once in order to complete this.

If I am wrong about this and others have found a way to complete the task with only two kills at once, please respond.
