Pragmata: How to Unlock the Secret Ending

To unlock the secret ending in Pragmata, you must first complete the main story, which then makes the "Unknown Signal" post-game mode available on the title screen. Selecting this mode with your completed game save data will load you into a save point just before the final boss. This mode introduces a new sector with a series of 10 new missions, similar to the main game's training missions. After the first "Unknown Signal" mission, you can return to previous sectors or your shelter. Returning to the shelter will unlock new equipment upgrade levels, thanks to the level five shelter key provided. You can upgrade your equipment as desired. Most "Unknown Signal" missions have specific unlock requirements, such as achieving 100% completion in certain sectors or defeating new enhanced bosses. These requirements will appear as you approach the mission pods. Upon completing all 10 "Unknown Signal" missions, you will earn new outfits, a new weapon, and a secret mod. Equip this final prize mod and take the tram back to the final area of sector six to re-fight the final boss. This will be a significantly harder fight. After defeating the boss and playing through the credits, you will receive a trophy/achievement and a new story snippet, which constitutes the secret ending.
