How to Unlock PRAGMATA’s Secret Ending

Before we get into things, HERE THERE BE SPOILERS for the end of PRAGMATA.

So, you stopped the threat of Dead Fillament, and Hugh managed to keep his promise to his newly adopted robotic ward. PRAGMATA is done and dusted, now it’s time to give Lunatic mode a thorough playthrough, right? Well, yes and no.

Once the final boss of the game is completed, the player is awarded with a few niceties for their achievement: they can now start a New Game+ with most of the upgrades they have painstakingly collected, the aforementioned Lunatic difficulty mode is unlocked for those seeking a challenge, and both Hugh and Diana get a few fun cosmetics. However, there is one final addition that may be a bit misleading: Unknown Signal.

This post-game mode purports to contain a few extra challenges that will net the player further cosmetic goodies and bragging rights. While this is true, there is more to it!

Found in the main menu, starting it up will plop the player back in time to just before the big fight with Eight. Cabin has detected the titular Unknown Signal somewhere in the Cradle and tasks our heroes with checking it out. Using the Tram, the duo go on to find a hidden wing of the facility, housing a giant Cabin robot and ten Sim Pods, in addition to a sealed chamber containing the promised cosmetics.

NOTE: A Completed save is necessary to start up Unknown Signal, so be mindful if you want to try out NG+ first.

each pod has a requirement that must be met before they open. These usually take the form of either achieving 100% completion of a specific area or defeating an enhanced version of the many bosses the player has faced.

Now, it should be noted that 100% completion does not mean finding every Mini-Cabin or upgrade material, but only the listed chests and items seen in the map selection screen. Using Diana’s Scan ability makes this a simple process.

The enhanced bosses themselves can be found in the same area as the original battle. While tough, they’re not much of a challenge against a fully kitted-out Hugh and Diana.

As a sidenote, completing the first challenge pod, which teaches the player to use the new Jackhammer weapon, will unlock Shelter level 5, allowing for further upgrading of weapons and opening up the final Stamp Card with both some additional lore and… “interesting” costumes for our main leads.

Once the requirement is met, the pods open. Complete them all, and you will open up the sealed chamber housing the critical component for unlocking the secret ending: The Black Box mod.

To unlock the ending, simply equip the mod and go fight Eight for a second time. Upon defeating the final boss, the last cutscene will play, now with an added extra at the very end.
