The Collection Chamber: SENTINEL: DESCENDANTS IN TIME

THE DOOR OPEN ONCE IN A LIFETIME. THAT MOMENT IS NOW.

The legacy of the Tastan tombs has long held some of the most profound secrets of an extinct race of people. Some believe the tombs hold a fabulous treasure, others say wealth is in the knowledge and technology left behind by this advanced civilization.

You must now search for the truth as you enter the tombs on a dangerous quest for riches.

As you begin your strange and perilous journey, a female sentinel, a holographic image with advanced A.I., left by the ancient Tastans to guard their sacred caverns, awakens. She appears throughout your quest as a guide with a sometimes benign purpose, but other times with calculated intentions. You will soon realize that behind the mask of illusions, the sentinel is much more than she appears to be - her dark purpose might threaten your very existence.

What truths will you uncover...
8 brilliantly inspired, diverse worlds
Unravel wonderous mysteries
More than 20 mind-bending puzzles

There was a brief moment in the early 2000s when Polish developer Detalion looked poised to become the rightful heir to Cyan's puzzle-adventure throne. After years of uninspired imitations of Myst, the genre was in something of a slump around this time with only a few bright spots shining though. Detalion's very own Schizm: Mysterious Journey - a classic that's not only still sold today on GOG or Steam (as is their first game Reah) - may have been their magnum opus, even earning a belated revival in the form of Nemezis that resurrected the company after its demise in 2005. The game that brought about that unfortunate even was 2004's Sentinel: Descendants in Time. It may have been financially unsuccessful, but their last release in the company's original form has just as much going for it as their other adventures. Like Detalion's previous work, it's beautiful, maddening, deeply atmospheric, and perhaps a little too clever for its own good.

The game's story comes courtesy of Australian science-fiction author Terry Dowling, adapted from his short story The Ichneumon and the Dormeuse. Set nearly two millennia into Earth's future, the game casts you as Beni, a reluctant tomb explorer forced into the infamous Tomb 35 after a criminal kidnaps his sister. Inside waits the Dormeuse - a holographic artificial intelligence tied to the long-dead Tastan civilization. In theory, this should provide fertile ground for rich worldbuilding and philosophical sci-fi. In practice, Sentinel keeps most of its narrative frustratingly out of reach. There are barely any environmental clues or historical fragments to flesh out the Tastans beyond vague conversations with the Dormeuse herself. She spends much of the game appearing like a detached digital goddess, teasing Beni with cryptic musings and half-explanations while the player is left piecing together scraps of meaning from implication alone. This leaves the game in something of an identity crisis. The worldbuilding is intriguing but emotionally distant, with the story largely playing second fiddle to the puzzles and surreal locations.

Tomb 35 itself is something of an enigma; a cavernous hub area filled with dormant portals leading to fragments of worlds once cherished by the Dormeuse in century's past. Each domain is essentially a self-contained puzzle realm with its own visual identity and mechanical gimmicks. Solving the puzzles in each area rewards you with a crystal shard that slots into a central plinth back in the tomb, unlocking access to new areas. Your inventory barely exists beyond them. It's a satisfyingly simple means to gatekeep progression without locking you in a mental dead end. If you can't figure out the puzzles in one world, you can leave in the hope that it would click while exploring another.

And what worlds they are. Detalion's artists absolutely revel in creating strange alien dreamscapes filled with strange yet familiar devices. One moment you're wandering through floating islands made of metal and stone suspended in an endless sky, the next you're navigating a serial of wooden boardwalks in what appears to be an abandoned fishing village. From volcanic islands to snow-capped mountains, these places often feel less like believable civilizations and more like giant interactive puzzle boxes. For example, in the gardens of Tregett, the tower in front of you is your only point of interest. You will need to link up some metallics buds with electricity to access its elevator. Then, you'll have to colour match the edges of a bridge so you can identify symbols on some flower-like windmills. This will lead you back to ground level where you can collect a crystal before leaving. These worlds aren't designed to simulate life, they're designed to challenge your brain. Yet despite this, they remain consistently memorable.

Of course, the real test of a Myst-inspired adventure is the puzzles, and Sentinel delivers far more often than it does not. Some puzzles are genuinely brilliant exercises in pattern recognition and environmental deduction. Others feel like the tedious machinations of a struggling mathematician. Thankfully, Sentinel mostly sticks to the self-contained puzzle chains within each world rather than hiding clues halfway across the game world. Still, trial-and-error rears its ugly head more than once. That Tregett bridge puzzle I mentioned earlier, for example, required a number of switches to be flipped to figure out the right combination which I never really understood how each flip affected the whole. There are rarely any Indiana Jones-style diary pages or schematics to help you reach that "aha!" moment, but for the most part the puzzles can be easily understood if not solved.

The only help you get from the game is an immersion-breaking hint system that can thankfully be turned off in the Settings menu. Whenever you reach a puzzle, bright yellow instructional text appears on the top right of the screen. They are brief and specific so I recommend veterans turn it off or else risk ruining your enjoyment.

Unlike the still images of Myst, Sentinel uses Monolith's LithTech Jupiter engine for full real-time 3D exploration. This still felt enormously impressive at the time when it was not unusual for other games to still be using pre-rendered graphics. Being able to freely wander these bizarre worlds, peer over sheer cliffs and study machinery from any angle only adds to the immersion. The controls remain pleasantly straightforward even today. Traditional keyboard-and-mouse movement works perfectly well, while mouse-only players can hold the right button to move forward. The downside to full 3D, however, is that important clues can be much easier to miss. What would have been carefully framed in a slideshow adventure now risks hiding slightly off-camera behind a railing or tucked away into the environment. To combat this, transparent arrows appear when interactive elements are nearby, but unlike the hint system, it cannot be turned off.

Technically, the game still holds together surprisingly well considering its age and modest budget. The lighting and environmental detail often punch far above what you'd expect from a niche 2004 adventure title, while Daniel Kleczyński's soundtrack quietly reinforces the lonely, contemplative mood without becoming intrusive. The voice acting is a little uneven, though the Dormeuse herself leaves a strong impression thanks to her calm, almost amused detachment. There's a strange melancholy hanging over the entire experience too, perhaps unintentionally amplified by the knowledge that Detalion wouldn't survive much longer after release.

What ultimately makes Sentinel: Descendants in Time worth revisiting isn't necessarily its story or even its individual puzzles, but the consistency of its atmosphere. Even its flaws become oddly endearing after a while. The vague storytelling, the wildly inconsistent puzzle difficulty, the lonely silence between conversations - it all contributes to a sense of exploring something ancient and unknowable. Few adventure games capture that feeling quite so effectively.

It's a real shame Detalion closed its doors only a year later. With Reah, Schizm, and Sentinel, the studio carved out a distinct identity among early-2000s puzzle adventures, creating games filled with atmosphere or imagination. Sentinel: Descendants in Time may not reach the heights of Myst or Riven, but it absolutely deserves recognition as one of the better descendants of that design philosophy. Difficult, beautiful, occasionally infuriating, and unmistakably ambitious, it stands as a fitting final monument to a studio that perhaps never quite got the attention it deserved.
