Lazy Marathon is a mod that has a lazy bastard achievement counter but increased to accommodate for the costs found in marathon mode. It fails the game when you go over the limit and also includes a button to toggle crafting to make sure you don't accidentally make something. You have 222 available crafts which is 2 more than you need to finish the game so craft wisely.

If you think this is an insane challenge, you'd be right. It takes a long of time to mine the thousands of ore you need to get some decent automation (a good burner inserter setup is recommended early game) but after that it moves at a better pace. Most guides for Lazy Bastard are still applicable besides the numbers, such as this one by r3nko. I will provide some of the numbers and a couple early game tips below for those interested.

Notice

this mod overwrites the objective GUI, so the new in-game tutorials and scenarios will sometimes have part of the textbox overwritten. This will be fixed in a future release. The recipes in marathon mode may change in the future as well, in which case I will update the mod. It is currently built for build 0.15.3. This is my first mod/scenario, so feedback is appreciated! It was fun learning how it all works and I want to give thanks to the people in the Factorio discord channel for helping me work things out. You can report bugs by sending me a message on steam.

Crafting Numbers

To get an assembler 1:

Pump: 10 iron, 10 copper.
Boiler: 8 iron.
Steam engine: 100 iron.
Power pole: 1 copper.
lab: 70 iron, 50 copper.
40 science: 160 iron, 40 copper.
Assembler 1: 35 iron, 15 copper.

combined: 383 iron, 116 copper.

To get an assembler 2 (crafts inserters, miners etc):

440 science: 1,760 iron, 440 copper.
Assembler 2: 70 iron, 25 copper.

combined: 1,830 iron, 465 copper.

TOTAL: 2,213 iron, 581 copper.

After that it should not be very difficult to create electric miners and start pumping out science.

Have fun!
