|overview=
PL event has five chapters in total, laid out similar to the manner of the two previous event [[Isomer]] and [[Shattered Connexion]]. A story told by separate routes, routes have with no dead ends and will not require backtracking. But however players cannot complete one route at a time, all story nodes have to be played, if one route is met with a dead end, simply find the another unlocked nodes and progress.

Most event nodes are pure story nodes, a small amount of reward will be given after completion. Chapter 1 contains 6 normal combat nodes and 2 challenge nodes. Chapter 2 contains 5 normal combat nodes and 1 challenge node. Chapter 3 contains 4 normal combat nodes and no challenge nodes. Chapter 4 contains 9 normal combat nodes and 2 challenge nodes. Chapter 5 remains to be seen.

|overalldifficulty=
Chapter 1 and 2 combat nodes difficulty is arguably easier than the previous story events, players with lv60+ 3x expanded echelons can complete with ease. Chapter 3 may require level 70+ and 4x expansion echelons. There is no hard (EX) mode for this event, but there are challenge nodes available, challenge nodes test both the player's echelon level, diversity and performance, as well as their wits.

=== Event Currency: Crates ===
Similar to previous story events, crates are available from completing event chapter maps, however the daily limit for crates is lowered to 40 a day as oppose to the previous 60 a day. Completing normal stages to obtain 6; 8; 10 crates while completing challenge stages to obtain 6; 10; 12 crates. The following dolls are possible loots from the event crates:
*{{doll name|SL8|RF|5}}
*{{doll name|Contender|HG|5}}
*{{doll name|P90|SMG|5}}
*{{doll name|AN-94|AR|5}}
*{{doll name|MG36|MG|5}}
*{{doll name|S.A.T.8|SG|5}}

=== Pushing Crates mini-game ===
A new mini game mechanic added to challenge chapters, similar to the manner of the old "Pushing Crates" or "Sokoban" games.<ref name="sokoban">Wikipedia entry on [[wikipedia:https://de.wikipedia.org/wiki/Sokoban|Sokoban]], a game where the player tries to push crates into certain positions</ref> ''to-do''

=== Portable EMP ===
There is a new kind of bomb that player can utilize on the battlefield. Similar to goliath bomb, player can pick it up using either ordinary echelon or HOC unit from its tower and hurl it up to enemy units. Target will suffer reduced stats and unable to move for one turn, similar to what EMP generator does.

=== Shore Gun ===
Certain map will feature shore guns that player can control. Ordinary echelon or HOC unit must stand on the gun node for player to control it. Player can use it to destroy selected target that present on the map within the gun's range. The gun can only shoot one target per turn.

=== Water Valve ===
Water valve can be found in some maps. Destroying them using goliath bomb will leak water into the battlefield. Echelon that caught in the leakage will suffer reduced stats such as movement speed reduction. It affects both allies and enemies indiscriminately. Similar to contamination zone, the water leakage can spread across the battlefield.

=== Welfare Shop ===
To ease the limited edition doll looting process, the game introduced a form of "guarantee" system to the grinding process. In addition to have a chance at getting the desired dolls from specific enemy and the battle conclusion, players also gain another currency, with said currency, players can exchange all the limited edition dolls available in the event. Currency exchange shop can be found on the top tab of the Kalina's store.

Defeating enemies/concluding battles that drops 3* and 4* rarity dolls will yield {{Icon|Nova Medal}}x1 Nova Medal, while defeating enemies/concluding battles that drops 5* rarity dolls will yield {{Icon|Platinum Medal}}x1 Platinum Medal. Doing challenge nodes will yield double the amount of medallions. Medal cost for dolls will be dependant on the dolls rarity, 5* Rarity dolls will require {{Icon|Platinum Medal}}Platinum Medals while 4* and 3* Rarity dolls will require {{Icon|Nova Medal}} Nova Medals.

* A polarized light is a light source which light waves are filtered to a specific polarization.<ref name="polarization">Wikipedia entry on a [[wikipedia:Polarizer|Polarizer]], a tool to filter specific light waves</ref>
* Many map nodes are connected like a sine wave<ref name="sine">Wikipedia entry on [[wikipedia:Sine_wave|sine waves]]</ref>
* Although Polarized Light is considered the most impactful Event in the game, it was also left drastically unfinished with 2/3rds of the story being left untold. This is largely due to the sudden Covid-19 outbreak in February, causing majority of the citizens in china to self quarantine themselves for their own safety. This resulted the event lasting for 2 weeks longer than usual totalling in almost 6 weeks, but also resulted in Chapter 5 being unfinished and rushed. The epilogue of Polarized Light will be continued in Chapter 13 as a result.
** It'll be unlikely that the event will last this long when it reaches other servers.
