# Applying a tech research cost multiplier

In Seablock, some players like to apply a tech research multiplier to increase the length of the game. Due to the sheer number of items and recipes available, it's common to unlock techs faster than you can utilize them when you are playing on the default 1x multiplier settings. By increasing the tech cost by 5x, 10x, or even 100x, you progress slower, and have a chance to savor Seablock longer. Many feel 10x strikes a good balance between progressing too fast vs too slow. There are also some masochists that apply a 100x multiplier.

Seablock is already a complex mod. If you aren't experienced with heavy overhaul mods, then playing with the 1x multiplier, which is the intended Seablock experience is highly recommended. If you are experienced with Seablock, or if you are comfortable playing through a complex mod in general, then a multiplier run can be a fun way to challenge yourself.

## How do you apply the multiplier?

### Applying the multiplier to the FTL techs

In the startup screen, visit the "Settings / Mod settings" page, and uncheck the "SpaceX ignore tech price multiplier" checkbox.

### When starting a new game

Then, when you are starting a new game, go to the "Advanced" tab and enter the multiplier you wish into the "Price multiplier" input box.

### When applying a multiplier to an existing save

If you want to apply the multiplier to an existing game, run the following command in the console:

```
/c game.difficulty_settings.technology_price_multiplier = 10

```

The above command applies a 10x multiplier to the current game. Adjust the value to set the multiplier you wish.

### When applying a multiplier to a multiplayer game

See the example settings file in `./data/map-settings.example.json`, modify the `technology_price_multiplier` key and save the file as a name you wish (i.e. `my-map-settings.json`). Then create a new save with the following command:

```
./bin/x64/factorio --create saves/my-save.zip --map-gen-settings my-map-gen-settings.json --map-settings my-map-settings.json

```

## How does the multiplier work?

The multiplier will apply to the techs past starting from "Water Treatment".

If the default 1x cost was 30, then a 10x multiplier will make that tech cost 300.

## Any tips for a high multiplier game?

The most important tip is to join the Seablock Discord to share knowledge and discuss about the unique challenges facing a high-multiplier game. There is a great community of friendly and knowledgeable players who will help in your journey. Also, /r/Seablock subreddit contains a wealth of great information.

If you want to apply a multiplier, you should be, at a bare minimum, be comfortable with the fundamental mechanics such as trains and fluids. A multiplier run is not the time to learn how to setup a reliable LTN system. Also, using a planner like YAFC, Foreman, Helmod, and Factory Planner is highly recommended.

Also, the following mods are recommended for a megabase needed to finish a high-multiplier game:

* Seablock megabase fix - Fixes the over-production bug that can occur when the items produced by prod modules are not affected by the production cap.
* Solar sails - Adds an expensive item that produces 200MW to reduce UPS cost in a lategame build.
