The game world is 3D and built from blocks, à la Minecraft (which itself was inspired by Infiniminer, an earlier Zachtronics game). The blocks you can use in your factory include conveyors, welders, pushers, sensors, rotators, lifters and so on. Lots of ways to manipulate the blocks you're working with.
The lightweight story and mechanism design aspect of the gameplay draws a lot of comparisons to SpaceChem (also by the same developer), though it's a good deal easier.
Infinifactory contains examples of the following tropes:
- Alien Lunch: Two of the Overlord levels involve processing meat for the Overlords. One has some lemming-like creatures, the other an alien whale. You, however, get food pellets in your cell. When the resistance rescue you, you can talk to Dave. He'll mention the food at the cafeteria, saying, "Just keep telling yourself it's fishcake."
- Aliens Speaking English: Averted for the Overlords, played straight for the resistance. Presumably the Overlords' opinion of you is too low to bother translating anything for you.
- Apocalyptic Log: The Failure Log audio recorders you find on the bodies of previous engineers throughout the Overlord campaign.
- Big, Bulky Bomb: The bomb you build in the last level of "The Heist".
- Book-Ends: The opening and closing cinematic both have your character driving along a country road listening to the radio.
- Chekhov's Gun: The Overlords give you trinkets from Earth during your performance reviews, transported in using a little trapdoor on their desk. This is how the Resistance gets in their bomb to rescue you.
- Continuous Decompression: When Resistance saves you, they blow up a hole in the Overlord ship. This trope follows, before your character is sucked through.
- Dying Alone: Floyd in his last message. He sounds pretty satisfied with it, though.
- Frickin' Laser Beams: Second part of the resistance campaign involves use of lasers to break apart blocks. Unlike Eviscerates, lasers have no range limit and need to be triggered.
- Food Pills: Food pellets, in this case, provided by the Overlords and dumped into your sink.
- Incredibly Obvious Bomb: It's beige, boxy, and beeps loudly, and scrawled on the front are the words "GET DOWN!" Cue the Resistance busting you out.
- Interface Spoiler: You can see that you are missing several types of blocks before you are introduced to them, even when you are nearing the end of Overlord campaign which hints the second campaign.
- Even during the Resistance Campaign, you're still missing one block, and one segment of the campaign is suspiciously empty...
- Jet Pack: You have one as standard on your space suit. There's no fuel limit, so you can fly freely when building your contraptions.
- La Résistance: The Resistance busts you out at the end of the Overlord campaign, and put you to work on finding a way to escape.
- No OSHA Compliance: It's entirely possible to fall to your doom on many of the work sites. The Overlords don't even bother to remove the bodies.
- Programming Game: You design a factory and then run it until you have ten outputs.
- The resistance has fishcake for food. Which other game used fishcake as a standard food? Zachtronics' earlier game SpaceChem.
- One of the areas in the Resistance campaign is called "Atropos Station". Guess which other Zachtronics game has an "Atropos Station"? SpaceChem, again.
- Look out the window of one of the missions in the Atropos Station area. See that planet with the lava rifts covering its surface? Looks a great deal like Hephaestus IV, the area immediately prior to Atropos Station in SpaceChem.
- Stealth Pun: During one of your performance reviews, you are given a live chicken and instructions to eat it. A fade to black and the sound of you biting its head off follow.note
- Teleportation: Later in the game you get to use to a teleporter cube to send items to other location. Most puzzles involve taking apart object and then reassembling it on the other side.
- This Is a Drill: One of the tools you have in your arsenal is a drill that allows you to destroy any block they touch.
