Survival Scoring

Scoring in Survival is separated into 5 categories: Mission, Combat, Survival, Looting, and Performance. Each category is counted separately, and totaled up to give an agent's final score in a game of Survival.

Ranks
There are 6 ranks in Survival, depending on what score threshold one passes. Scoring Master Rank for the first time awards the player with the Survival Instincts Trophy/Achievement, as well as completing said Commendation and adding the Killer Instinct patch to the player's collection.
 * Rank 0: No Rank (0-599)
 * Rank 1: Novice (600-1749)
 * Rank 2: Trained (1750-3999)
 * Rank 3: Skilled (4000-7499)
 * Rank 4: Expert (7500-9999)
 * Rank 5: Master (10000+)

In addition, for playing on PvP Survival, your score will be multiplied by 1.20 to reward the player for the extra risk of potential combat against other agents.

Tips to Score Higher

 * Remember that all enemies in the Dark Zone are Level 30, allowing you to gain more points for killing fewer enemies.
 * Take a Food and Drink before boarding the Helicopter; the score potential for Hunger and Thirst are much higher than that of simply holding on to the Food and Drink.
 * Counting only the core objectives (Mission without Time Sensitive Materials and 1 Hunter), you score 4000 and 100% for Thirst and Hunger grants another 1000, totaling 5000, not counting other categories. You always start out at GS 38 (190 Points) which is definitely going to rise as you find better gear, so plan out how to get the other 5000 Points necessary.
 * Killing 4 Hunters equates to 3200 Points, 1600 for the Hunters Defeated, and another 1600 for the Punisher bonus.
 * This applies for every 4 Hunters killed, meaning 8 Hunters equates to 6400 Points, assuming the group can take on that many enemies.
 * Don't be afraid to use a Medkit if low on health; they can also be crafted, and the points possible for Never Downed can be pivotal in gaining Master rank.
 * It is actually possible to extract without grabbing the Antivirals. Don't forget them if you need the points!
