-* +5 for picking up a flag.
-* +20 for then capturing the flag.
-* +X for killing someone, where X is:
-	* +5 for every kill they've made since last death in this match.
-	* `15 * kd` ratio, with variable cap based on player's score:
-		* capped at X * 10 for < X * 100 player score
-			(eg 10 for 100, 20 for 200, 40 for 400+).
-		* capped to 40.
-		* deaths > kills gives 0 score
-	* Limited to 0 ≤ X ≤ 100
-	* If they don't have a good weapon: half given score.
-	  A good weapon is a non-default one which is not a pistol, stone sword, or crossbow.
