all alone achievement help

Having trouble with getting the “all alone” achievement, it’s virtually impossible to get in a game of infection on a defiant map. so i’m wondering if anyone wants to party up with me and try and get it?
I have 1 spare controller, it would help if you could have one too. Cheers!

I won’t be on today, but tomorrow after work for a little.

Should probably have done this in the recruitment forum. Still, I would like to help.

This is why Halo Reach needs a title update for the Defiant achievements so they can be earned on any map

You don’t need to get it on a Defiant map?

I have most of the achievements and have earned little to no of them on a Defiant or Noble Map… I got most of mine on Swordbase…
