hey I've been looking for a free Bo1 overkill tool for quite some while now and haven't seem to have any luck finding one. Can someone please help me out and send me a like to one, thanks.
I'd suggest you to tell by the title prefix that if you're looking for PS3 or Xbox 360.
If you're looking for Xbox 360, there are no free released tools for this.
gamer7112 has his AIO tool, which is paid, but it's very good and has what you're looking for (or so I've heard)
