Notoriety

Info
The purpose of the Notoriety system is to create a relationship between the difficulty of scoring a kill ("frag") and the value of that frag that is directly proportional. The more difficult the frag is, the more valuable it is, and the easier the frag is, the less valuable it is. Your Notoriety score, and not strictly your amount of frags, determines your spot on the scoreboard. It is quite feasible to end a game in first place with half as many frags as the player in second place.

Killstreaks
Scoring multiple frags in one life will generate a Killstreak bonus. This bonus will go up to +100% Notoriety per frag.
