Oh to be a structural engineer tasked with wandering broken-down buildings and tunnels.... To call Infra a walking sim would be to somewhat underestimate its purpose as a game. Instead, it's more notably an exploratory/puzzle game that tasks you with keeping as close an eye on your surroundings as you possibly can. If you're not checking every nook and cranny laboriously, then you're not playing the game properly. In short, you're an engineer named Markku, or "Mark," working as a structural engineer in a city that leaves you believing you may be the only person capable of properly working on or fixing any part of its INFRAstructure. Indeed, in some ways I'd call this game more comedic than one might expect. I have to imagine that people who've worked the very job that Mark does may have had similar thoughts of: how in God's name does this city even run, man? It's actually absurd how much is broken down and not in working order until you come along. It's as if the very city itself would have fallen apart were it not for Mark's careful eye and unbeatable tenacity. Setting that part of the humor aside, there's also plenty of little jokes for the discerning players - and in fact there's just a lot of stuff hidden away throughout the game for players to find in general. I was fairly thorough for most of the game (up until the last couple chapters where I began to lose a bit of steam thanks to the game's surprising length) and I'm confident that there's a lot I just never found or saw. I'm aware of some ARG-type puzzles strewn about the game, and just looking at the achievements that I didn't get (over half of them!) I can tell that there's just a lot to chew on in the game even beyond the core playthrough experience. But, that's all just gravy, really. For me, one playthrough is more than enough, being an incredibly long game for what it is that really asks you to be as patient as possible with it. There's a lot of jank, in short. Many puzzles ask you to interact with movable objects, this being from time to time a fairly irritating experience (the effort of stacking boxes, for example, can prove to be more involved than you'd think it should be). There's also a lot of moments where puzzles are solved merely through what information you have rather than any real problem-solving. There's also plenty of moments where there's no real puzzle to solve at all and instead it's just a matter of finding easy-to-miss keys laid around in relatively arbitrary manners. Where this all comes to a head is in chapter 9, in Turnip City. In reality, I actually rather liked this area, but it will absolutely be a major test of your patience. For me, this was pretty much the last of my patience as thereafter I was pretty much ready for the game to be done. Thankfully, this is about 95% of the way through, so I didn't have much left! Even beyond the stuff that is explicitly time-consuming such as Turnip City, there were also several moments in which I experienced bugs or glitches that artificially inflated the time it took me to do anything. I won't hold that to the design of the game itself, which I think is generally quite good, but instead just to the fact that it's an old game built in an engine that is somewhat prone to jank. But, despite all the frustrations I had playing this game, and despite the fact that I truly was ready for it to be over a few hours before it actually ended, I come way from Infra incredibly pleased. It's a totally unique experience, there's just nothing like Infra out there that I could say. Sure, it grabs onto that loveliness of urban exploration that other games have touched upon before, and the environments you go through have all been seen before in bits and pieces, but the whole of this game is a singular vision, to me. If nothing else, what Infra did for me was give me a real appreciation for what all goes on behind the scenes. There's so much that goes into the act of running a city, so much that no one thinks about. It's easy to forget about all the things that lay beneath your feet, hidden behind walls of buildings you could never fathom the insides of if you weren't already familiar. All those hallways you've never gone down or doors you've never seen behind, Infra explores them all and highlights a part of urban life that most simply do not let their mind wander to. I love too the solitude of it all. In many ways, Infra is an unsettling, almost outright creepy game. For the most part, there's zero human interaction. After you leave your place of work, you're pretty much by yourself for the next 20 hours. But, at times it doesn't feel that way. All the time you're exploring, no matter where you are, there's always an impression of life. There's graffiti everywhere, things strewn about in ways that suggests people were there not too long ago, and on rare occasion there's even this oppressive feeling that you're not quite alone. You'll find blankets and mattresses, suggestions that these abandoned places were called home by some unknown person you'll likely never meet. The story too is fun to follow. The paranoia-inducing mystery unravels as you go through the game. You begin to piece together this massive blight of corruption inflicted upon Stalburg by ne'er-do-well business owners and capitalists that seek to exploit their workers and citizens alike. My favorite part of this, I think, was the discovery of what happened to the people lost in an in-universe infamous metro accident. Really, that's all I have to say, but I also wanted to touch upon a little extra note: At one point, I was looking at one of the many newspapers you can find on your travels and I noticed that one of the blurbs was about a horrific aircraft accident that led to the loss of 273 lives. The blurb explicitly stated this was the single worst airplane accident to ever happen in the United States. This made me curious about whether that happened to be true, as I assumed this was just a fabricated accident created for the game to just fill out a newspaper and give it a sense of reality. In checking out the wikipedia article dedicated to the very list of deadliest aircraft incidents though, I found that the article was actually about a real event and the claim was indeed true. Just thought that was a neat little touch, is all. (And yes, it's not the deadliest INCIDENT, but accident for sure - that one you're probably thinking of, after all, was not an accident).
Recommended with reservations. You are Finland's most insanely dedicated civil engineer. Tunnels may be collapsing and buildings may be exploding around you, but that's not gonna stop you from photographing every single piece of decaying concrete and broken pipe. I really enjoyed the vibe of exploring the environments and trying to spot problems to photograph. The gameplay is split between that and figuring out how to fix pieces of infrastructure such as dams and water treatment plants. Those puzzles were generally good, however some of them were obtuse enough for me to have to consult a guide. Sometimes you'll find yourself stuck somewhere just scouring and re-scouring every inch until you find some obscure thing that you missed. However, when the repair puzzles are good, they do feel pretty satisfying. The game is also plagued by some annoying design decisions: - You can't look at your inventory, so unless you happen to see what's written on a key tag (if it's even visible) before you pick it up, you have no way of knowing what the key goes to. - The most absurdly short battery life of a flashlight and camera that I've ever seen in a video game. It's not really a problem past the first few chapters, but it is kind of annoying to juggle. - What counts as something worth photographing seems a little inconsistent and arbitrary at times. Broken windows are usually of interest, but not doors that are off their hinges. Sometimes Mark wants to photograph "out of order" signs, and sometimes he doesn't care. Fortunately the game does clearly communicate when you're pointing at something that counts and, to the game's credit, I only remember one instance of something being photographable but it not being clear why. - It's possible to fail at some puzzles, and early on I don't think they really do enough to communicate that you *can* permanently mess up fixing stuff before it happens. Failing to fix certain pieces of infrastructure locks you out of some content much, much later in the game, and the game is long enough that it would be a huge pain to replay everything just to see that extra content. All of that, and the game is pretty long for what it is and I'd say overstays its welcome. I could have done with it being 3/4 or even half the length. Still, overall I'd say I enjoyed my time with it, and if it sounds interesting to you I'd say it's worth picking up on sale.
While the game has some small issues, I couldn't help but get sucked into the story. The gameplay, while simple, is very enjoyable and needing to explore and look around for glaring problems and issues within the city's infrastructure really tickled the engineering part of my interests. Some puzzles were a bit repetitive (find and carry object from A to B for example is used a lot in this game), but others had me connect dots from the surrounding environment which I really enjoyed. Additionally, I've always been fond of Urban exploration, especially of big industrial complexes whether they're newly abandoned or have been left to degrade decades ago. With its environments, which seem to push the source engine quite hard, they have managed to really encapsulate desolate, old and crumbling structures that once thrived. Being able to explore and make sense of everything is fascinating. I am honestly amazed with the environments built by the Devs, and honestly wish that the game was even longer (even though it took me 22h to finish first time) so I could continue exploring. Personally i recommend it if you prefer games where you have to figure out the story and lore yourself, instead of seeing it through cutscenes and having it handed to you via dialogue.
INFRA (created by Loiste Interactive ) is THE walking simulator. If you enjoy exploration, puzzles and detailed environments, this is absolutely for you. Add a nostalgia bonus if you like Valve's Source Engine (or simply like Portal / 2 or Half-Life 2). (Yes, this game is made in the Source Engine). This is absolutely my favorite game ever!
