Usually you could get three levels of spree-based medals. For an example, Sniper Spree, Sharpshooter, and Be The Bullet. I would like to have a fourth level included, where the medal is a golden eight-pointed star, just like the Rampage medal. These are the names I came up with:
For killing with the Sniper Rifle: Area Code
For killing with the Shotgun: Animal Hunter
For Splattering: Hitting And Running
For killing with the Energy Sword: Shredder
For killing as a Juggernaut: Rhapsodical Monster
For infecting humans: I, Zombie
For killing zombies: Hells Jinkies
For killing with a Plasma Grenade: Like Glue
For killing with the Gravity Hammer: Batter Up
For assisting: Designated Killer
For driving while another person kills: Bruising Cruiser
For having a partner spawn to you: Partners In Crime
