Combos and Badges


 * Combos are shown when you achieve to kill at least 3 soldiers with max 2 seconds between each kill. The more soldiers you eliminate within that logic, the higher the combo, thus the bonus XP award you receive on top of the XP for killing each soldier individually.


 * Badges are visual overlay images that show you that you did something special, like a kill streak, dying 5 times in a row without killing anyone, teamkilling at least 2 allies with one explosion, dogtag for killing an enemy soldier, etc.
