A fun little shooter in the style of an advanced Wolf3d clone, with simple weapon and health upgrades scattered about secrets hidden within the various levels. The levels are a bit sparse and could use a tad more variety. Beyond that, I got exactly what I wanted.
Really liked it! Woflenstein-like but with wonderfully designed levels, the guns can be upgraded and have alternate fire modes, the enemies are easy read. This is perfect to either get your kids into FPS as their first shooter or for when you just want something straight forward and simple yet never boring! Worth every penny I paid for it!

Extranuem is a game that I got on day one. I love the original Wolfenstein 3D and any shooter with nice crispy pixel art, 90 degree angles and no verticality. The game has been on my radar since the demo dropped. When I got it in early access, I played through the first chapter and waited for the full release. When it was released, I was unable to play it immediately and only got around to it last month. I had so much fun, I decided to get all the achievements. And it was worth it. I wanted to do a review since then but only got around to it now. Anyways, here's the review. Extranuem is a Wolf 3D inspired game but also so much more. Instead of strictly sticking to the limits of Wolf 3D, it expanded on it with new ideas, great level design and just plain fun enemy designs. Extranuem has 3 episodes consisting of 8 levels each. 6 main levels and 2 secret levels each. That might not sound like much but it took by about 4 hours to play through all the levels once. The rest of that time was getting the achievements. The levels were well designed, with open areas, small claustrophobic areas and even a train level. My personal favorite is the secret level that is a homage to Doom's E1M1 Hanger level. Just like the rest of the game, it's just not a copy but so much more. You start out like the original E1M1 and follow it to the exit. Great nod. But then the exit opens up to another area. And another area. It's such a good level, with nostalgia and surprises mixed into it. That also describes the games levels in general. Nostalgic with surprises. The weapons are fun to use and often have secondary fire modes (That is hidden away in secret areas, giving you incentive to explore the levels). You have a shotgun, chainsaw, energy gun, rocket launcher and a few more. Most follow the typical lineup but they are so fun to use, I didn't mind it that much. The only weapon type not present is a room clearing super weapon, but I din't really miss it that much. The enemies are fun to fight and all have a kind of chibi-style. I actually felt bad killing some of them. The enemies range from fast melee enemies, enemies that jump attacks you, small low damage ranged enemies and big, heavy hitting ranged enemies. The way they are combined makes them really fun. Over all, I had a smile on my face during my time with Extranuem. I enjoyed my first play through and getting all the achievements. Now, is the game perfect? No, of course not. There were a bug or two (Nothing game breaking), it is a bit short if you just want to play through the levels once and it is simple. The thing is, I enjoyed the game. I got 12 hours out of it and it was intended to be simple. So I have to recommend this. I don't know if the dev is planning another game but if he does, I'll be first in line for it.
Really enjoyed the presentation of Extraneum. On the surface, it displays as a cozy Wolf3d-inspired title. While you progress through, you're met with more intricate layouts, more clever secrets, some snazzy weapon upgrades, and an increasing variety of enemies. This to me set it apart from a lot of other shooters in the category. Difficulty settings let you scale things to how you like, and I do appreciate that the harder difficulties do not lead the player to play in an exceedingly tedious manner. I didn't feel pressured on Gruesome to corner camp and bait every encounter, but I was punished for poor movement and poor gunplay, and I think Extraneum really strikes this balance well. Secret hunting is also heavily encouraged and rewarding. I definitely enjoyed my run through the game. Everything felt worthwhile to pursue in a map, and everything from the map presentation, to the combat loops, to the music all added up to just a really cozy experience. Great stuff.
Extraneum is an absolutely adorable 2D shooter with 3D environments, and I would call it a Wolf 3D-like, but it would be doing a great disservice. This is so much more than Wolf 3D, with its choices for level design being more stylistic, but don't be fooled; it looks better visually with height variation in ceilings. Far gone are the days where you have to put up with annoying hitscanners playing ping pong with your health; the game tries its best by giving you non-cheesy enemies. While I'm sure that having levels be almost entirely flat with some slight floor dips might seem boring for some (except the few levels with actual height variation), all levels are themed, with the first episode seemingly more city-like with some more industrial-like areas, the 2nd featuring suburbs and brown-like texturing (no, not that kind of texture), and the 3rd follows a more lab-like theming; I mean, the game even has a moving train level like what? That's so cool and such a nice break from the norm, the secrets are also accessed by finding secret items, which encourages exploration, neat! But if I had to pick favourites, it would be 1-A, 1-3 (favourite music, btw), 1-5, 1-6, 2-4, 2-5, 2-A, 3-1, 3-A, 3-3, 3-4 (flows really nicely), 3-6. As you can see, I like a lot of the levels, some more than others, and that's a good thing. It's really hard for me to find favourite maps these days, but all of these stuck out to me as being very fun. I will make a note that the 2nd boss is, uh, almost a cakewalk. Extraneum also offers a nice minimap on the HUD, which you can zoom in/out and enlarge. Speaking of the HUD, you can actually scale the HUD size, a big plus and something all games should strive for. As someone who also plays on a console, which Extraneum is unfortunately not available on, sometimes the HUD is too small, and I am sitting from a distance playing. It's just horrible when you can't see anything.
Fun, chaotic, fast paced Doom-like action with a solid soundtrack. Amazing that only 3 people worked on the game--it's quite fun! You guys did great!
Extraneum, developed by David Jalbert and published by Hellforge Studios, is a retro-inspired first-person shooter that pays homage to the classic shooters of the 1990s while carving out its own distinct identity. From the moment you step into the game’s dystopian world, it’s clear that Extraneum embraces the fast-paced, adrenaline-fueled gameplay that defined early shooters like Doom and Quake, but it also injects modern design sensibilities that elevate the experience beyond simple nostalgia. Set within a mysterious high-security facility called Project EXTRANEÜM, players take on the role of a security guard thrown into chaos as the facility becomes overrun with bioengineered monstrosities. The narrative is sparse but effective, providing just enough context to motivate your descent through the sprawling, increasingly dangerous levels. The game’s core appeal lies in its level design and exploration elements. Unlike many straightforward shooters, Extraneum encourages players to thoroughly explore each of its 24 meticulously crafted levels. Hidden passages, secret rooms, and scattered upgrades reward those who take the time to search beyond the obvious paths. These upgrades, which include health, armor, and ammunition enhancements, feel like genuine rewards that encourage curiosity and make the challenge more manageable as you progress. This focus on exploration gives the game a layered feel, turning each level into a puzzle of sorts, where uncovering secrets becomes just as important as clearing out enemies. Combat in Extraneum is fluid, fast, and brutally satisfying. The arsenal includes a diverse set of 12 weapons, from trusty pistols and rapid-fire machine guns to powerful shotguns and more exotic armaments. Each weapon feels distinct in its handling and effectiveness, encouraging players to adapt their approach depending on the enemies they face and the layout of the environment. The game features 12 enemy types, each with unique attack patterns and behaviors, demanding that players think on their feet and switch tactics dynamically. Boss fights punctuate the campaign and provide intense, memorable confrontations that test not only your reflexes but your ability to strategize and use the environment to your advantage. Visually, Extraneum embraces a pixelated, retro 3D aesthetic that beautifully captures the spirit of early polygonal shooters without feeling dated or clunky. The environments are richly detailed, blending grim industrial settings with eerie sci-fi elements that help immerse the player in the unsettling atmosphere of the facility. Lighting effects and environmental details create a sense of depth and mood that contrast well with the sharp, colorful sprites of enemies and weapons. This art style strikes a delicate balance between nostalgia and modern polish, making the game accessible to fans of classic shooters while still appealing to newer players who appreciate stylized visuals. While the game excels in its core design, it’s not without imperfections. Some players have reported occasional bugs and performance drops, particularly in larger levels with numerous enemies and complex geometry. These issues, while rare, can momentarily disrupt the flow and immersion but don’t significantly detract from the overall experience. Additionally, the game’s heavy emphasis on exploration and secret hunting may not appeal to players who prefer a more linear, straightforward shooter. Those looking for quick, run-and-gun action might find Extraneum’s slower pace and attention to detail less immediately gratifying, but for players willing to engage deeply with the level design, the rewards are substantial. In summary, Extraneum is a thoughtfully crafted throwback that successfully blends the best elements of classic first-person shooters with modern touches. Its intricate level design, engaging combat mechanics, and atmospheric presentation create an experience that feels both familiar and fresh. The game challenges players to be both precise in combat and thorough in exploration, making each victory feel earned and satisfying. For fans of retro shooters or anyone looking for a challenging, atmospheric FPS with a strong sense of place and personality, Extraneum is a standout title well worth playing. Rating: 8/10
Hidden Gem среди бумер шутеров. Челы умудрились сделать на вульфоподобной архитектуре уровней настоящую красоту, которую интересно играть, интересно рассматривать и интересно исследовать. Прошел на 100% на платину. Единственный достаточно раздражающий минус для меня это то, что после прохождения секретных уровней нужно заново проходить прошлый уровень на обычный выход, чтобы продвинуться дальше. Иногда это довольно бесяче было, учитывая размеры некоторых уровней, особенно во втором эпизоде.
This game brought me back to the days of Wolfenstein 3D and Doom/Doom 2/Doom 3. Nice pixel graphics, scrolls smoothly and quickly, nice secrets, set the degree of difficulty to what you want so you can play it how you want. Highly Recommend!
