Call Of Duty Infinite Warfare Zombies Souvenir Coin Combo Guide
Blue + Red + Blue = Window Laser Trap. You can use these to rig the windows where the zombies spawn at, not as useful as some of the others but good for camping a window.
Red + Green + Blue = Kindle Pops. These are little candy pieces that you place on the floor. When you shoot them they start on fire and become a fire trap for a little while. This is good for setting a trap in a doorway or a hall way.
Green + Blue + Blue = Electric Trap. This is placed down and shoots arcs of electricity from the where it is put down.
Green + Blue + Green = Boombox. Toss this down and the zombies will go to it and dance, does not work on bosses. You can use this to mow them down while they are distracted.
Green + Red + Green = Sentry Turret. You can place the turret and it will mow down any that come near it, not super strong but helpful.
Blue + Blue + Blue = Toy Ship for the special Face Melter weapon if you use it at the Blue Souvenir station in the Journey To Space Area. It also popped out a Sentry Turret. You put it on a cut out right around the corner from the station but you need other components as well.
