The object of this Puzzle Game is to build things. You have no idea what they are for and you don't really care.
You are given a basic set of instructions of what to build and then, by the use of converyers and things, you feed it into a recepicle to see if it was built correctly.
The game starts out with just a few simple tools to build your 'thing' and then adds more as the game progresses.
If you are like me and HATE arcade puzzle games that make you guess, by trial and error, what to do then you will Love Infinifactory. It starts you off letting you know exactly what you have to create and you can take your time to design a machine that will produce it. No hurry. No rush. No guessing.
I've even sat in a waiting room with a pad and pencil and sketched out ideas to try when I got back to my computer (Love my big screen;)
I've only been playing about 6 hours or so but if it keeps doing what it has done already....I'm in puzzle heaven!

Basically a 3D version of SpaceChem with the same mechanics. Start with basic materials and work out how to get them to the drop-off in a certain configuration. Well made, nice graphics & interface.

This Is one of the best puzzle games I have ever played.

There, I said it, whew that feels good to have that off my chest.

Zachtronics really knows how to make a good game. You will be incredibly frustrated in places after thinking "this should be easy enough" before reasising that you will need an IQ similar to that of a Steven Hawking-Albert Einstein hybrid to complete this game.

Now don't get me wrong this game is hard, I spent most of the time feeling like my brain cells were being blasted my microwaves. But that just increaces the reward from finishing a really dificult puzzle.

To all those who are looking for a puzzle game they can sink hours into all the while thinking your brain is going to explode, this is the game for you because it is

Very cool little puzzler. I wasn't sold on the visual style at first but it grew on me. If you're into puzzlers, definitely give it a go. It's one of my favs, along with Portal.

If you're a logical thinker, then this game will give you lots of cool puzzles to reason out. You can spend a good bit of time optimizing your solutions after you first figure out how to complete each level.

If you're not a logical thinker (illogoical?), then this game will still be great fun as you create crazy, Rube Goldberg type solutions to the puzzles.

The only constraints are the puzzle space made available and the creativity you bring to bear.

Really good puzzle game. Gets too confusing/tedius for me in the later levels, but whatever. I still had fun.

It is a fun, puzzle, game with simple rules and concepts. Could they improve it? Yes. Is it worth the current price? Still yes. It is a fun game, that I will always love. It has good simple machanics, and is very reliable. Get it, it's good.

I do wish they allowed you to move through blocks, to edit inner functions, but with the area tool you can move stuff away to get in a machine. Though I wish it was a bit more reponsive and easier to control. That and I really wish they would allow you to rewatch cut scenes :(

That is all though. A great game. Get it.

I have 50 mind-wrecking hours in this game and just realized after finishing every puzzle for my alien overlords that that just unlocks the second campaign... /o\

Seriously though, very cool game. I'm not quite as in love with it as with TIS-100 but that may well be a matter of taste.

Turning cute things into meat

*I like to create contraptions and I have this tingling feeling when I sit back and watch them operate

*I like to have to stop playing a game for 3 days because I'm not good enough to find a solution and have to think about it in the shower

*I like to have to use a pen a paper to help me play video games

*If I ever get abducted by aliens, it'd be totally cool to help them build war machines etc. so they can continue their invasion of earth

*Building machines that transform cute animals into packaged meat products sounds pretty cool.

Infinifactory probably isn't for everyone, but if the above list appeals to you, dive in, you won't regret it.

Sometimes I spend my lunch break at work playing games. I spent one of those precious hours last week building a factory in Infinifactory. For the full 60 minutes I was engrossed in testing layouts and aligning conveyors and wiring sensors, only to discover at the end that my design was flawed and simply wouldn't work. Instead of falling to frustration, my brain kept churning through solutions until it struck upon one, and it stuck with me for the entire day until I could spend hours more that night constructing it.

This is the crux of what makes Infinifactory so amazing, that even failure is an engrossing and enlightening experience. And you're sure to fail now and then as the game asks more and more of you, from moving boxes from one wall to another all the way to breaking down starships and building cannons out of the pieces. It's the kind of puzzle game that presents you with a seemingly insurmountable task, and through only the basic systems presented it helps you experience that delicious eureka moment when everything clicks. I'm getting ahead of myself here, but it's hard for me to contain my admiration for everything Infinifactory accomplishes.

You play an unnamed human who gets abducted Fire in the Sky style by aliens. Instead of probing your tender orifices, however, they just task you with building factories for them. Every puzzle takes place in an exotic location with hatches that produce objects, and a platform that demands a finished product made from those objects. Your job is to use your infinite supply of factory blocks provided to combine, separate, and rescramble the input into the appropriate output. As I mentioned before, this can be anything from linking three boxes together to constructing a missile to breaking down a whale into packaged meat.

The beauty of this setup is that you have simple tools that can be spun into factories of infinite complexity. Your basic work blocks are things like conveyors and rotators and welders that get the job done. Added to this though are sensor-controlled pushers and blockers, destructive grinders and lasers, and even programmable counters once you get far enough in. The combination of these elements allows you to create meticulously-timed networks of shifting lines and presses that can produce satellites, starships, and even fully-furnished rooms. And consistency is important as well, because every puzzle requires you to produce not one but ten of the requested object. The amount of combinations possible also means that there is no one solution for any puzzle, but a vast array of elegant or brutish layouts to experiment with.

Discovering the full potential of your blocks through the campaign will take well over a dozen hours, spread across upwards of thirty puzzles that gradually ramp up in complexity. As you progress so too does the story, conveyed through audio logs, meetings with your alien overlords, and some quality environmental storytelling. I won't spoil what happens at the end of the campaign but I will stress that it is one of the most pleasant surprises I've had in recent memory, especially in the additional content it reveals. On top of this is a wide-open testing mode, a custom puzzle creator that lets you set up your own scenarios, and a fully-integrated Steam Workshop that lets you share and download user-created puzzles of surprising quality.

Honestly I would be in love with Infinifactory if it had even a quarter of the content. There are few things as satisfying as watching a sprawling industrial complex churn out rovers or tanks in perfect rhythm, complete with hearty whirrs and clanks. The sound design deserves some special mention for the perfect effects and incredibly chill soundtrack (included free with the game!). And there's even an element of community with your solutions being rated against those of your friends on criteria like how fast they work and how much space they take up. This is a puzzle game that leaves nothing out, combining rock-solid design with excellent story, presentation, and spread of features. Infinifactory has easily claimed a place as my favorite puzzle game of all time, with a perfect balance of challenge and satisfaction.

It melts your brain until you remember that you can drop blocks in three dimentions, and gravity only matters to what you're producing.

Its a puzzle game and it makes me cry.

Pre-Release Review
Posted: June 30, 2015
How to solve a puzzle in Infinifactory:
1) Look at the output and think, "That's not so hard, let me put this here and that over there."
2) Run your experiment.
3) Swear because it's nowhere near what you thought it would be.
4) Swear again.
5) Come up with a rickety solution that works under one use case but falls apart on others. (This is exactly like some real-world programming!)
6) Marvel as your friends come up with more elegant, faster solutions.
7) Realize that you're having a tremendous time.

I don't know what Zachtronics has against the human brain or why he wants to punish it so, but I encourage his behavior. Great game, they've been very good about expanding it and refining puzzles. Recommended.

It's straightforward. The mechanics are simple. The purpose is clear. There's no confusion as to what you are expected to do and what tools you have to do it.

It's diabolical. The puzzles are sometimes bananas, requiring some pretty twisted logic and lateral thinking. While you strive for a solution, there's a constant nagging feeling that sometimes your solution is just inelegant and you need to do it better.

It's oddly darkly humorous. There's a strange undercurrent of defiance against your alien overlords, from listening to the audio diaries of the project managers who came before you, from resenting the food pellets that drop into your cell when you complete sections of the game.

It's also gorgeous - not so much in graphics, which are perfectly adequate, but in the efficiency of the presentation. No main menu. No weird visual effects cluttering up the screen. No unnecessarily ostentatious setpieces. No splash screen! On load, the game drops you right into where you left, so you can literally load the game and get building. There's a gorgeousness to seeing your machine, your factory do its work, and the satisfaction that comes with it makes the effort all the more worth it.

It's one of the most interesting puzzle games I've ever played, and I'm enjoying it hugely despite not being great at coming up with particularly creative solutions.

Early Access Review
Posted: January 19, 2015
This game is freaking awesome. Don't let the Early Access tag scare you, because it's pretty far off, and it's already worth every full-priced penny in it's current state even if the developer decided to walk away tomorrow (which I'm sure Zach will not do)

The best thing about this game (and SpaceChem before it) is the awesome feeling of "♥♥♥♥ yeah, I'm such a badass for doing this ♥♥♥♥", that you get after each level completed. And in a way you are, as this game is a lot harder and smarter than most games out there.

- "I'm such a bad-♥♥♥" feeling
- Great tutorial/intro
- 3 solution slots per level
- Spacechem pyramid dangling in the rear view mirror in the intro
- Learning curve is very well balanced
- Stable and polished

- No in-game recording and sharing tool (ok, this shouldn't be a Con, but we got spoiled...)
- No or too few data points to compare performance (this will turn into a Pro later, as this feature is awesome)

Graphics are functional but nothing to write home about, neither Pro nor Con, but certainly good enough.

I recommend you pick this up at full price if you can, as this is one developer that deserves more money so he can make more good stuff like this. The fact that H1Z1 is topping the top selling list while people put this game on their wishlists waiting for a sale just makes me want to cry. So go ahead and pick this one up sooner rather than later.

Infinifactory does this thing I love. It makes you earn your enjoyment of it.

You load up your next task and take a look at what you'll need to produce and what materials you'll have to produce it with. Immediately, some ideas start popping and you think, "Okay, I know what to do." Ten minutes later, everything's wrong and you realize you were being naive. But you keep building and trying things because that's just who you are. An hour later, things start to click. You still feel dumb as bricks but you're at least smarter than you were ten minutes ago. Then, long after you began, you have a working production facility. You are a genius. The smartest of the smart. Nothing can bring you down from this high.

Then you get to see how your solution rates against everyone else who's finished that same factory and it turns out you're actually pretty much middle-of-the-road. But maybe you can go back and adjust some things and score better? Or maybe you've learned some things and maybe your vision and clarity has leveled up and just by starting fresh you can shave your score by half?

Whatever the case, you have had a blast. You've been challenged for the first time in who knows how long. You've had fun and by all the things that you might even consider swearing on, you've earned that fun.

SpaceChem is one of my favourite puzzle games of all time. I adore its design and its open-ended puzzles. I was interested in Infinifactory because I liked SpaceChem. I was also skeptical. I didn't like the idea of doing puzzles in a 3D space. I didn't like the aesthetic. I didn't like the whole factory concept.

I needn't have worried. Infinifactory is actually probably better than SpaceChem. Which hurts me to say. But it doesn't hurt too much because I'm busy having tons of fun.

I can be very brief about this game:

If you like Zachtronic's SpaceChem, you will like Infinifactory.
If you love SpaceChem, you will love Infinifactory.
If you hate SpaceChem, you will hate Infinifactory even more.
If you think SpaceChem is too hard, you will find Infinifactory undoable.

If you never played SpaceChem, what are you waiting for? There is a free demo available. And if you enjoy it, rest assured that you will enjoy Infinifactory too.

Heartily recommended for all those who love tough puzzles and enjoy building complex machines.
