What's up YouTube. It's your boy RoYL Killswitch back again. This time with a special mash up edition on Call of Duty: Black Ops 3. I'll be first to admit, I suck at Call of Duty. I might just be the worst (at best), but I've put together a "Best Of" video just for you. It wasn't easy but as you can see I've got it done so don't forget to like and subscribe. Also remember tell a friend to tell a friend to tell multiple friends..
