Boosters are a means of gaining an advantage (or disadvantage if it is a Badge of Honor) in a multiplayer match.
Boosters have to be bought from the multiplayer store, and can only be bought after reaching a certain level. Players can only equip two Boosters at one time, one in slot 1 (upper) and one in slot 2 (lower).
When the player reaches level 51 (stylized in game as the Roman numeral I), they can purchase badges of honor. These are special boosters which give the player a disadvantage in a match. However, for every five kills a player gets while a badge of honor is equipped, they earn a medal worth a substantial amount of money.
