Downpour

Rain World: Downpour is a paid DLC released for PC on Jan 19th 2023. Initially developed as the More Slugcats Mod by the community, it was brought on as official content when Akupara Games became Videocult's publisher, after Adult Swim. Downpour also incorporates several other community-made projects, including Jolly Co-op, Expedition and Rain World Remix, a free update to the vanilla game adding accessibility and quality of life options.

Subregions
=Expedition Mode=

A place where you can select your favorite slugcat and go into expeditions with specific objectives to complete and gain rewards

=Safari Mode=

In each region of the game players can find a red unlock token, which unlocks that region for Safari mode. In this mode the player controls a gray Overseer while observing the different creatures. The player can control individual creatures to create unique situations and experiment with how they interact.

In the menu for this game mode players can select which region they want to use (karma gates do not work), and deactivate the rain so there is no time limit.

Creature Control

Selecting a creature while controlling the Overseer and then pressing space allows the player to take control of it. Pressing Jump moves the Overseer's selection to a random creature in the region, making it faster to find an interesting one to control rather than going from room to room. Pausing the game shows how to control that creature, as each has different abilities not available to the Slugcats, like biting, charging, pointing, etc. If the creature the player is controlling dies, they will return to playing as an Overseer.

Challenge Mode
In this mode you can play as which Slugcats you choose with the restriction of playing with Slugcats you haven't unlocked darkening the levels of that Slugcat, each Slugcats have 7 unique levels with their own gimmicks and focus on the individual Slugcats abilities. Each level can be quite demanding and requires you to know some ingame features and skill to be able to proceed. giving levels you completed a green checkmark to show that you have beaten it previously. Some levels but without spoiling much has different content that only shows up in this mode.

Co-op Mode
This lets you play the campaign normally but with the aid or hindrance of a friend that progress alongside you, letting you be able to pick whichever slugcat you want freely if it hadn't been picked yet.
