## What is Assembly Line 2?

Welcome to Assembly Line 2, the sequel to the factory-building and managing game.

Assembly Line 2 combines elements from idle and tycoon games. Make the most money by using different types of machines to build an assembly line to craft resources and sell them. Unlock upgrades to make it more efficient and expand your factory.

The goal is simple, build resources and sell them. Starting with a few machines and very basic resources, and using them with more advanced machines to craft and create more complex resources.

Your factory will continue generating money even when you are offline. When you return to the game you will have piles of money waiting for you, but don't spend it all in one place!

While Assembly Line 2 is an idle game, because you make the layout of your factory, it is up to you to optimize it to make the most money possible.

Don't worry if you get lost with all those machines to build, the game offers an information menu so you can see what each machine does at any time. It also offers information on each resource price, so you can make decisions on what to craft. You can also see stats on the amount you are producing.

Features:
- 21 different machines to build and optimize the best factory.
- Tons of upgrades to increase productivity.
- Around 50 different unique resources to craft.
- Multi-language support.
- Backup your progress.
- No internet required.

### 5/5 — It’s perfect as is

*2026-08-29, version 1.2.22*

I really enjoy this game, my only real issue is how slow the first part of the game goes, but I understand that’s how it was intended, very addicting, and very fun.

### 4/5 — Don’t watch the ads they don’t work

*2026-08-27, version 1.2.22*

Watched one ad for 15.8 M, no reward, watched it all the way through. Thought, oh well it bugged I’ll wait for the next one. Same thing. The ad rewards do not work, don’t waste the 30 seconds

### 4/5 — Save glitches every once in a while, but not constantly

*2026-08-26, version 1.2.22*

So this is a few weeks later, so my previous save was indeed being weird, but the game is still a little laggy, still very good, ⭐️⭐️⭐️⭐️

Highly recommend

### 5/5 — My save was being weird

*2026-08-20, version 1.2.22*

So last review I said it kept making me lag and locking me out of building mode, but that was because something was being weird and after a deletion and reinstall I’m back in the game, and it’s INSANELY good, I highly recommend you try it. ⭐️⭐️⭐️⭐️⭐️

### 3/5 — Game is okey

*2026-08-14, version 1.2.22*

Good game but progression is very slow, you will be stuck with the same buildings for long periods of time

### 5/5 — This game is PERFECT!!!

*2026-08-07, version 1.2.22*

This game not only has no forced ads, but it’s extremely fun to play! I recommend!!!!

### 5/5 — Best Mobile Game!!

*2026-08-06, version 1.2.22*

Generally, out of EVERY SINGLE game i have played (on mobile), this is single-handedly the BEST-i really can not think of a way to make this any better, truly the perfect game!

### 5/5 — Assembly Line 2

*2026-07-25, version 1.2.22*

Make a new update, please

### 1/5 — Could not even figure out how to play

*2026-07-18, version 1.2.22*

I spent 10 minutes trying to figure out how to play the game. If you exit the tutorial early it doesn’t allow you to go back in and there’s no instructions anywhere on how to play the game. Eventually, I found out that I had spent all the allocated money and was unable to buy the right machinery because the game glitched. Ended up just deleting it from my phone.

### 5/5 — Best game ever

*2026-07-16, version 1.2.22*

I’ve played this game 4 times to completion it’s amazing
