The gameplay for 13 Sentinels takes place in 3 parts. One part is roughly translated as “Recollection,” the other is “Collapse,” and last but not the least is “Investigation.” Recollection is the first part and shows the adventure segment, Collapse is the combat part which reveals battles against invaders, and Investigation consists of the archive.
Tips on how to play
You can opt to kick off with clearing as much of the Recollection segment and then focus on the Collapse section afterward. Another option is to cycle between Recollection and Collapse.
Keep it balanced
Although you have free rein over how you want to play 13 Sentinels, the best experience is to juggle among the three sections. Certain sections affect others. The sections are linked through the materials that allow you to progress with the other sections. Materials like meta chips which can be obtained from the adventure portion help you go through the battle portion, whereas clearing the battle portion allows you to unlock mystery files necessary to advance the archives.
Recollection Tips (Adventure)
Look for signs
The recollection section has many icons to take note of. First off, you need to pay attention to the Cloud Sync. Check the upper right corner for an icon. If a red mark shows up, it means that there are still some mysteries left to uncover. Use Cloud Sync on various passers-by until the red mark no longer appears.
Use Trial and Error to trigger Cloud Sync
Timing makes a difference when interacting with the NPCs. In other words, you may have to change the order of NPCs that you talk to. For instance, you’re inside the classroom with filled with students.
Try to talk to student A and then speak to student B and then check to see if something happens. If not, approach student B and then go back and ask student A. Having more NPCs may require multiple attempts to get it right to trigger the Cloud Sync.
Look for clues
When in doubt, check the chart for clues. Hover to a section that shows “???” to find a hint. Use clues to formulate a better approach to interacting with the students.
Collapse Tips (Combat)
Optimize the team
Team Organization or party formation plays a vital role in battle mode. The key is to get familiar with the four elements: pilot type, combat bonus, favorable matchup, and HP and EP management.
Each pilot belongs to a certain type with each having a specialty. The ideal set up is to deploy pilots that have advantage against the approaching enemies. Look at the team’s BP and make sure that it does not reach the limit. If you assign pilots that share the same type and weapons, you can lower the BD to prevent overload from occurring.
In between battles, you can recover gauges using rest. To use rest, press the Square button on the formation screen. However, if you opt to let your team take a break, you will have to forego the chain bonus that comes when the team achieves a winning streak. Aim to win as many battles as possible without relying on rest to build a high score.
Analyze the enemies that you will be pit against on your next match and then adjust the team organization to gain an upper hand. Large enemies are best handled by G1 and G3 pilots, while airborne enemies fare poorly against G2 and G3 pilots.
Conserve HP and EP
HP and EP of mechanics do not regenerate. You can restore HP using one of two ways, one is to use weapons while the other is to use a meta skill. Meanwhile, you can also gain EP using two ways, one is to simply defeat an enemy and the other is to use its equivalent meta skill. Learn how to conserve the two gauges to stay longer in battle.
Learn to use meta chips
In the early game, there are four steps that you need to know in order to conserve meta chips efficiently. First, you must play the Recollection section to collect 20,000 chips. Move to the Collapse section and then raise the meta system to level 5 to earn an additional 10,000 chips. Improve the Meta skill to level 2 to earn 5,000 more chips. Last but not the least, unlock HP recovery, EP recovery, and forced cooldown skills to gain 5,000 chips.
Investigation Tips (Archive)
The investigation section shows the archive which contains files and reports that are not shown in the main story. Make sure to collect files to have a better understanding of the convoluted story.
How to obtain Mystery Files
Mystery Files are reports that can be examined in the archive. You need to play the adventure and combat segments to expand your mystery file collection. Below is a list of ways to obtain files:
- Raise the level of progression in the main story (Recollection).
- Obtain an S Rank in battle (Collapse).
- Finish all missions (Collapse).
- Clear each stage once to unlock the First stage clear reward to earn MP (Mystery points) and then spend them for mystery files (Collapse).
