Survival/Rewards

Rewards
Besides the bonus amounts of materials, experience, and mods from the increase in enemies compared to normal missions, certain rewards can be awarded at the end of the mission if the mission is a success. Mission rewards will vary depending on the level of the mission's enemies (the starting level; this tier does not scale during a mission as higher level enemies spawn) and also depends on the amount of time spent.
 * Enemy level tier (in average):
 * Tier 1: Level 1 - 10
 * Tier 2: Level 10 - 20
 * Tier 3: Level ≥ 20
 * Note: While most missions obey these enemy level tiers, there are a few exceptions, such as Hymeno and Cambria. Refer to the table above for a more accurate list of mission enemy level tiers.
 * Time spent Drop Rotation (rewards cycle every 20 minutes):
 * Rotation A: 5, 10 minutes; 25, 30 minutes; etc.
 * Rotation B: 15 minutes; 35 minutes; etc.
 * Rotation C: 20 minutes; 40 minutes; etc.
 * Rewards stack the longer you play.
 * At 15 minutes and every 20 minutes after, you are guaranteed to receive a Void Tower key.
