• Successfully killing a boss solo, which is stupidly hard to do but will reward you with a whopping 30,000 points to skyrocket your position on the leaderboard. Especially the Fallen Booster.
• Taking the top position on the leaderboard and holding it for a prolonged period of time. As the top player, everyone is alerted to your position and a good chunk of the server will be out for your blood, so not only surviving, but eliminating the challengers to your throne is incredibly gratifying.
  • Forget being the top-scorer, how about killing the top-scoring person on the leaderboard? Usually, this will net you enough XP to instantly secure you a spot on the board as well, particularly if they had been reigning for a long time.
• Successfully outplaying and killing a player that is significantly higher level than you. Incredibly difficult, but oh so rewarding.
• It's possible to kill a player much stronger than you if you catch them at low HP from a skirmish, or just accidentally hit them with a stray bullet in a firefight. Considering this will usually level you up several dozen times, if this happens in the middle of a losing fight, you can easily use your sudden burst of XP to turn the tables on your attackers.
