Entering the universe of Hell is Us is essentially like plunging headfirst into a dark and surreal world where the player must fend for themselves. There are no maps to guide you or glowing arrows to show you where to go; the key lies in analyzing every clue and tool available to unravel the plot while facing creatures that seem straight out of a nightmare.
Join Rémi Letam on a journey filled with secrets and mysteries, where the gameplay blends the tension of soulslike games with organic exploration. To leave nothing to chance, we've prepared a comprehensive walkthrough that covers everything from the most brutal boss battles to the most hidden corners of Hadea, ensuring that no valuable item is left behind.
Fundamental Mechanics and Survival

To survive in this hostile environment, it's vital to understand that the game prioritizes a minimalist interface. The lack of explicit markers forces the player to pay close attention to their surroundings and use the Data Pad to organize information. Progress is divided into three main acts, structured around missions called "Investigations."
- Armament and Combat: You can equip two weapons and switch between them on the fly. Each has unique combos and traits, so it's worth experimenting to see which one best suits your playstyle.
- Protection and Defense: Defensive gear not only boosts stats but also grants special effects that can be passive or activated under certain conditions. Like weapons, you can combine two pieces of armor.
- Glyphs and Upgrades: Throughout the world you will find glyphs (such as Animosity or Recoil) that can be applied to your equipment once you locate the Blacksmith.
Advanced Exploration: Beyond History

Hadea is a place where it's very easy to miss important content. There are so-called Timeloops , black spheres that distort space; closing them is essential to clear the map of enemies and advance safely. In addition, the game offers side activities that enrich the experience:
The Mysteries function like true treasure hunts where you must find keys to open chests or secret doors. On the other hand, Good Deeds consist of helping NPCs; completing them grants invisible points that can be exchanged with specific merchants, but be aware that some characters disappear as you progress through the story.
Detailed Tour: The Senedra Forest

At the start of the adventure, Rémi finds himself in the Senedra Forest. After exploring the riverbank and collecting the Gold Medallion near a waterfall, the path leads to Caddell Farm. Here, we meet Ernest Caddell, who gives us the key needed to enter the forest and informs us about the location of the Acasa Marshes.
Following the sound of wind chimes, we'll reach an APC where a wounded soldier will ask us for a favor: to retrieve a first-aid kit from a nearby camp. Along the way, it's advisable to detour to the cliffs to find the Caddell Treasure Clue Note and the research item called the Scorched Bell.
The Dungeon and its Enigmas

After delivering the first-aid kit, we'll receive an Ancient Mechanism to open the door to the ruins. This puzzle requires rotating three columns based on images found on nearby stone slabs. Once inside the dungeon, the game introduces actual combat and starting equipment: the Drone, the Lymbic Blade, and the OMSIF Poncho.
Within these facilities, the Drone is essential for translating ancient texts. For example, clues like "sinners are taken to the tower" help unlock the doors. As we explore, we'll find key objects like the Ram's Head Medallions (Viridian and Crimson), which are indispensable for unlocking secret rooms containing the Queen's Decree Journal and powerful glyphs.
Towards the End of the Journey
The path will lead us through treacherous trenches where Lymbic Entities appear, enemies more complex than Hollow Walkers. After overcoming these areas, we'll reach the Tower, where we can obtain the Glyph of Animosity hidden beneath a staircase. Don't forget to interact with the woman trapped behind the iron door; this detail adds depth to the local narrative.
Finally, upon returning to Ernest Caddell, we discover the existence of the Blue Flowers, known as Adder's Tears, which are found in Cynon Lake. The journey continues through Acts Two and Three, where encounters with the Keystones of Terror, Ecstasy, and Wrath put everything we've learned to the test.
Having complete control over your equipment, interpreting environmental clues, and closing time loops is what makes the difference between getting lost in Hadea and achieving 100% completion. From managing medkits and basic food supplies to solving pillar puzzles, every detail matters in surviving the creatures and understanding the dark undercurrent of Rémi's story.
