Underworld Ascendant is a single-player fantasy RPG built around stealth, combat, magic, and environmental experimentation. Its launch-era reviews were sharply negative, and later updates addressed parts of the game’s structure, AI, gameplay, and performance. Those updates matter when judging the game today, but they do not erase the original criticism or establish that every issue was fixed.
What is Underworld Ascendant?
Developed by OtherSide Entertainment and published by 505 Games, Underworld Ascendant launched on November 15, 2018. It is a first-person action RPG set in the Stygian Abyss. Steam presents it as a game where players combine combat, stealth, and magic and experiment with different ways to solve challenges. Steam’s game listing provides the official store description and platform details.
The appeal is the promise of an immersive-sim sandbox: rather than relying on a single prescribed solution, players are encouraged to make use of the world and their abilities. The key question raised by reviews is whether that freedom is supported by clear, dependable systems—especially in combat, quests, and progression.
What did reviews say?
GameSpot’s launch-era review
GameSpot awarded the game 2/10 in its 2018 review, titled “Underworld Ascendant Review: Going Under.” That score is a contemporary assessment of the release-era game, not a new evaluation of the current patched build.
#1 Best Overall
- LOVECRAFTIAN TWIST: Dive into the world of H.P. Lovecraft's cosmic horror in this Pandemic spin-off. Work together as investigators to seal gates and prevent the awakening of Cthulhu.
- CLASSIC COOPERATIVE GAMEPLAY: Experience the beloved cooperative gameplay of Pandemic with a chilling twist. Cooperate with your fellow investigators to thwart the ancient horrors.
- ELDTRITCH FIGURES: Immerse yourself in the eerie atmosphere with custom plastic figures of investigators, cultists, and shoggoths that bring the Lovecraftian world to life on your tabletop.
- BATTLE INSANITY: As you search for clues and face unspeakable horrors, beware the encroaching chaos that could drive your investigator to the brink of insanity. Keep your wits about you!
- MYTHOS POWERS: Encounter twelve Old Ones, each with unique powers that threaten the world. Adapt your strategy and utilize investigator abilities to confront these eldritch entities.
PC Gamer’s criticism
PC Gamer’s review also criticized the game, including the opacity of its systems. That criticism speaks to an important trade-off in the game’s design: experimentation can feel liberating when the rules are legible, but frustrating when players cannot readily understand how combat, magic, or objectives are meant to work.
These reviews describe a substantial gap between the game’s advertised systemic freedom and the experience critics encountered at launch. They should be read as launch-era coverage, not as proof that every later version plays identically.
Did updates improve the game?
OtherSide Entertainment published updates in 2019 that addressed several areas raised by the game’s troubled reception. The announcements establish the developer’s stated focus and changes; they do not independently demonstrate that all problems were resolved.
Rank #2
- DEFEND THE LAST BUNKER: Earth has fallen to an alien invasion, and a colossal Mothership looms overhead. Work cooperatively as Bunker Leaders to survive relentless attacks, rebuild your settlement, and ultimately destroy the Mothership.
- A UNIQUE MASHUP OF MECHANICS: Experience a tense, strategic blend of classic trick-taking and desperate base-building. Win tricks to secure vital resources, but be careful—communication is limited, and every card played matters!
- OUTSMART THE ALIEN SABOTEUR: You aren't alone in the bunker. An automated Infiltrator Deck represents a hidden alien shapeshifter sabotaging your plans. If the Infiltrator wins a trick, the Mothership attacks your defenses!
- DYNAMIC BASE BUILDING: Visually build your defenses using an innovative card-tucking mechanic. Attach People, Weapons, and Shields to your Buildings to make them operational, increase your armor, and unlock powerful abilities.
- SOLO OR CO-OP SURVIVAL (1-4 PLAYERS): Features a dedicated, fully-fleshed-out Solo Variant ("The Outpost") for solo gamers, as well as highly replayable co-op for up to 4 players. (The box says 2-4. Solo mode was added after printing.)
- Update 2, February 14, 2019: OtherSide said the update focused on the player journey, the structure of the Abyss, AI, and gameplay.
- Update 3, April 10, 2019: The developer announced frame-rate and loading-time improvements.
- Mac and Linux availability, August 2019: OtherSide announced availability on those platforms.
The announcements and update notes are available in OtherSide’s official Steam announcements. In January 2019 coverage, GameSpot quoted OtherSide as saying, “We convinced ourselves that the game was in more robust shape.” GameSpot did not identify an individual speaker for that statement. GameSpot’s launch-response coverage also discussed the planned update roadmap.

Is Underworld Ascendant worth playing now?
It depends on what you want from it and how much tolerance you have for rough or opaque systems. The original reviews are a warning about the launch experience; later patches make it inaccurate to treat the launch build as the only version that exists. But the documented update scope is not enough to promise a polished or fully repaired game.
- Consider it if first-person fantasy, stealth and magic combinations, and experimenting with environmental solutions are the main draw.
- Be cautious if you want clear objectives, immediately readable combat and progression, or assurance of smooth performance. The available update notes report improvements, not a guarantee for every system or PC.
Steam’s listing showed a Mixed user-review label, with 41% positive from 696 reviews in the snapshot accessed in 2026. That is a changing Steam-specific count and share, not a stable measure of all players or critics.

Rank #3
- UNIQUE TAKE ON CIV BUILDERS: You lead a grand civilization at the height of its influence, but can you save it from collapse? In Empire's End, 2-4 players compete to keep calamity at bay by bidding their way through disasters.
- FUN MECHANISM: Empire's End marries the intuitive and elegant mechanism of reverse-bidding with engine-building, long-term planning, and strategic depth. The result is a game with a quick tempo, abundant tension, and multiple challenging paths to victory.
- SIMILAR TO NO THANKS: With each disaster that befalls an empire, its people grow in wisdom and resilience. In the style of the modern classic game No Thanks, resources bid by all players will end up in the hands of the player who ultimately takes the disaster card. That player also gains a new ability, an innovation that reflects their empire's ability to adapt in the face of challenging times.
- MORE TO IT THAN DISASTER: Each turn, players move along a progress track that dictates whether they will face a disaster or another type of phase. Players can gain new resources during Economy phases, rebuild lost territories during Industry phases, and challenge one another during Military phases.
- PLAY FASTER WITH LIGHTNING MODE: Want a quick game instead? Our Lightning Mode in the rulebook plays the same as the regular game, but in fewer rounds!
