Modules

Modules act as modifiers to your run. Some are passive and active at all times, others need a certain amount of specific actions to trigger. Tip: The number of actions necessary will be visible on the module icon on the left side of the screen.

Overview

Ice Pillar Module

Modules are semi-permanent items that give passive perks, options, conditional rewards, and other bonuses for the duration of the run.

Unlike Cards, modules do not go into the player's hand to be played during a turn. Instead, modules are activated immediately once chosen or awarded during a run for the remainder of the run. Note that, many modules have conditions that must be met before their bonuses take effect. When choosing a module, it's important to understand how frequently or infrequently these conditions are likely to happen given the carriages, cards, and other modules the player expects to have during a fight.

For example, the first module seen in the game, Ice Pillars, comes with the first available Driver. This module is therefore already activated at the beginning of the player's first run. Its effect happens immediately, because its condition is "at the start of every fight." Therefore, at the start of every fight, an environmental hazard is spawned.

Modules persist between fights. At the end of a run, the player loses all modules (except the Driver's innate module), and they must be found again during each run before they can be activated.

For players coming from other deckbuilder games, modules are similar to relics.

Obtaining during a run

There are two ways of adding modules to your train during your run.

Convoys

Convoy encounter on the map

A random module can be acquired for free by destroying the Convoy Van of a Convoy. As one of the rewards after finishing that fight, a choice of one of three modules is offered, with a rare chance of offering a choice from four. Clicking one will immediately add it to your train.

Chop Shops

Chop Shop on the map

Chop Shops have a random selection of three modules for sale for Scrap. Players may purchase any number of these for various amounts of Scrap. Players may also pay 30 Scrap to reroll for a new random selection. The Scrap price for a module depends on its rarity and therefore power. The rare module in the screenshot cost 160 Scrap.

Progression across runs

Modules & Cards button at the left of the pre-run screen

Before starting a run, players may review their currently available modules and cards and may pay Spikes to unlock new ones. Unlocked modules are added to the pool, so that during the run when earning or purchasing a new module, the unlocked module may be a random option.

After ANOTHER DAY IN THE FOG, players are shown their Driver, Locomotives, Carriages, Modules & Cards, and the button to start the run. Once the run begins, the module pool is set for the remainder of the run.

Deactivating a module

On the Modules & Cards screen, additional modules beyond the Base Tier are revealed and unlocked in tiers. Once a module has been unlocked, it is guaranteed to be in the pool. If the player changes their mind, they may Deactivate a module. The choice to deactivate a module is only available once the entire tier has been unlocked. After unlocking all four modules in a tier, the player receives two deactivation options. Unlocking all in the second tier grants two additional deactivation options, and so on. For example, in the screenshot below, two tiers are fully unlocked, so there are up to 4 deactivations possible.

• 
  Modules available to be unlocked before a run
• 
  Unlocked modules can be deactivated
• 
  Once deactivated, the module icon in the tier list changes
• 
  A deactivated module can be activated again with the Activate button
