About this game
Description
Supplied by the Steam store
The Citadel Project, the last line of defense built by the Ancient Kings in an attempt to preserve what remains of humanity in the face of the Great Storm. Unfortunately, an evil force is consuming it from within... Will you be able to navigate the nightmarish, labyrinthine architecture of this mega-structure and uncover what happened?
You are nobody, just a simple prisoner who manages to escape from a cell deep within the Citadel. With only a few tools at your disposal, you must survive and find your way through its alleys and labyrinths, now turned deadly.
Master the shadows
You must remain silent and, above all, unseen by the many dangers lurking within the Citadel. The Citadel Project features a complex lighting system that dynamically calculates your exposure to every light source, allowing you to take advantage of every area of darkness, or even create your own using the tools at your disposal.
Eliminate your enemies
These infected guards and civilians are a real threat, but if you are stealthy enough, you can tear out the gangrenous growths on their backs. Be careful, don't leave bodies in plain sight, or the entire area will be alerted...
Use your brain, push away
Even if you can't fight and defeat infected enemies, you can still use your force to push away your foes, on the ground, off a cliff, on thorned barricad, … or even fall on them from above. Use the verticality of the Citadel architecture so that your enemies will no longer be a threat.
One crossbow, multiple bolts
Your main tool for surviving and progressing through the Citadel is your crossbow. Various types of bolts can be found throughout your journey, each offering new possibilities. Stay hidden and extinguish torches, reach new heights with rope bolts, or eliminate threats with fire bolts, the choice is yours.
Explore your environment
Take the time to explore your surroundings and discover useful resources such as ammunition, secret relics, and notes detailing the Citadel's history. More importantly, careful exploration may reveal new paths forward through the vast depths of the mega-structure.

Hotfix 2 - 0.9.6
Little second hotfix for the patch 0.9.6 to fix some issues.Fixed an issue where you could charge a push, release it and instantly parry canceling the push but placing you in a non desired state, disabling the capacity to use the sickle to attack.Fixed some minor issues related to stamina regeneration and use.Fixed an issue related to custom audio volume box not having the right bounds size and position, making some guard not detecting audio while being in very specific location of some areas.

Little hotfix for the patch 0.9.6 to fix multiple minor issues with the new rope behavior.Fixed an issue where the rope sound could sometimes not be stopped when player leave the ropeFixed an issue where the player could sometimes grab then leave the rope instantly when he was still on ground or almost.Fixed an issue where if a player keep SPACE pressed while grabbing a rope, he was automatically dismounted from the rope then jump out.Fixed an issue allowing player to have a big jump boost if he pressed dash key and jump key at the exact same time. But that being said, it was pretty fun, so I've integrate this as a feature (balanced, indeed, if you do this jump boost you'll go just a bit further than a jump while sprinting).

Disclaimer : Sorry for the inconvenience, long story short, how steam handle main game/demo steam hub and Patch/Announcement is a bit messy. I have enable a standalone Steam Community Hub dedicated to the demo. Like this, I can link build to patch note to better deliver informations to players. Wrong side, the new community hub discussions board is empty (don't worry, all previous discussions are on the main game board). A lot of progress has been made since the demo’s release (that is to say, barely two weeks ago). Rework of the climb feature, huge polish and improvement on the crossbow, the rope, the AI, a whole new melee combat feature, crouch slide, parry, ... And it's just the beginning ! Today's patch, a lot of cool things are coming. Major changes:Steam Achievements have arrived ! 13 for the moment, I'll add some more in next week.Huge improvements on the melee combat. Enemy no...
