Introduction
Risk of Rain 2 has one of the most expansive mod libraries of any roguelite on PC. Thousands of packages exist on Thunderstore covering every aspect of the game from new survivors and items to full gameplay overhauls, visual enhancements, and quality of life improvements.
The challenge is not finding mods. It is finding the right mods for a specific playstyle without wading through thousands of listings or installing packages that conflict with each other or undermine the experience rather than enhancing it.

What to Know Before Installing Risk of Rain 2 Mods
Installing mods without context leads to bloated profiles, unexpected conflicts, and an experience that feels chaotic rather than enhanced. A small amount of preparation produces significantly better results.
Two things matter most before building a mod list: understanding which mods require specific DLC and knowing which mods are compatible with the current game version.
DLC Compatibility and Mod Requirements
Mods for Risk of Rain 2 has two paid DLC releases: Survivors of the Void and the Seekers of the Storm expansion. Many mods interact with DLC content or require DLC assets to function correctly.
Key DLC considerations before installing mods:
- Mods adding content that references Survivors of the Void items or survivors will produce errors without that DLC installed
- Some balance mods adjust DLC items and produce unexpected behavior if the DLC content is absent
- The Seekers of the Storm expansion introduced changes to core game systems that broke a significant number of mods at release
- Always check a mod’s Thunderstore description for explicit DLC requirements before adding it to a profile
- Mods marked as compatible with the current game version on Thunderstore have been tested against the most recent patch
Building a Focused Mod List
The temptation when discovering Risk of Rain 2 mods for the first time is to install everything that looks interesting. This approach consistently produces unstable setups.
A focused mod list built around a specific playstyle produces a more coherent experience and is significantly easier to troubleshoot when something goes wrong.
The playstyle categories covered in this guide are:
- Vanilla plus: Small improvements that enhance the base game without fundamentally changing it
- Item and content expansion: Adds new items, equipment, and interactables while preserving base game balance philosophy
- New survivors: Adds fully developed playable characters with unique ability sets
- Difficulty and challenge: Increases game difficulty, adds new challenge conditions, or expands the Eclipse system
- Multiplayer enhancement: Improves the multiplayer experience with additional player count support and session quality of life
- Visual and audio: Enhances the game’s presentation without altering gameplay systems
What the Best Vanilla Plus Mods Offer
Vanilla plus is the most widely recommended starting point for new Risk of Rain 2 modders. These mods improve the experience without introducing content that overshadows or conflicts with the base game’s design.
They are also the safest category for multiplayer use as they typically require the least synchronization across player mod lists.
Quality of Life Mods That Preserve Game Feel
The following mods represent the most consistently recommended vanilla plus additions across the Risk of Rain 2 community.
BetterUI
BetterUI is among the most downloaded mods on the entire Risk of Rain 2 Thunderstore listing. It enhances the in game UI with item counters, DPS tracking, buff timers, and improved item descriptions without altering any game mechanic.
Players who struggle to track proc chains, buff durations, or exact item counts benefit immediately from its additions. It is purely a clarity enhancement with no balance implications.
ProperSave
Risk of Rain 2 does not natively support saving mid run. ProperSave adds persistent save functionality allowing players to exit a run and resume it from the same point in a later session.
This is particularly valuable for extended difficulty runs or players with limited session time who want to experience late game content without completing full runs in single sittings.
Run History and Statistics
Several Thunderstore mods add detailed run history tracking that records completion data, survivor usage, item pickups, and cause of death across sessions. For players who want to analyze performance and improvement over time, this category fills a genuine gap in the base game’s feedback systems.
Frame Rate and Performance Mods
Risk of Rain 2’s late game produces significant frame rate drops on mid range hardware as item counts and particle effects scale dramatically.
FixedSpawnRate and similar optimization mods reduce particle density and effect intensity during high item count scenarios without visually degrading the early or mid game experience. They are recommended for any system experiencing consistent late game performance issues.
RiskOfOptions is a framework mod rather than a content addition. It provides in game configuration menus for any mod that implements its API. Many mods in every category listed in this guide support RiskOfOptions, making it a foundational installation for any focused mod list regardless of playstyle direction.
How Item and Content Expansion Mods Change the Game
Item and content expansion mods are the second most popular category after vanilla plus improvements. They add new items, equipment, elites, and interactables that integrate with the existing Risk of Rain 2 item system rather than replacing it.
Done well, these mods are nearly indistinguishable from official content in terms of balance and integration quality.
The Best Item Expansion Mods by Category
Diluvian Tempest and similar item packs
Community developed item packs add curated sets of new items designed with Risk of Rain 2’s balance philosophy in mind. The best of these go through extended community testing before release and integrate with existing item synergies rather than simply adding flat stat increases.
When evaluating an item expansion mod, check the following before installing:
- Whether items have custom icons and descriptions matching base game visual quality
- Whether the mod is actively maintained and has been updated within the last two months
- Whether community reviews on Thunderstore mention balance or stability issues
- Whether the items interact with existing proc chains in ways that produce intended rather than accidental synergies
Elite and enemy expansion mods
Mods adding new elite types or enemy variants increase run variety and mid game challenge without requiring new survivor knowledge. They integrate with the existing difficulty scaling system and produce encounters that feel like natural extensions of the base game’s design rather than additions from outside it.
Artifact and game modifier mods
Artifacts are one of Risk of Rain 2’s most flexible systems for run customization. Several mods add new artifacts with distinct run modifying effects that expand the combinatorial possibility space significantly beyond the base game’s offering.
Common Problems and Solutions for Content Expansion Mods:
- New items not appearing in runs despite mod being enabled Confirm the mod and all its listed dependencies are installed and up to date in the active profile
- Game crashes when a specific new item is picked up The item mod may have a conflict with an installed balance or item modification mod. Disable item modification mods temporarily and test to isolate
- New items displaying with missing textures or placeholder icons The installed version may be outdated for the current game patch. Check Thunderstore for a more recent release
- New elite types causing disproportionate difficulty spikes Some elite mods have balance settings configurable through RiskOfOptions if that framework is installed. Adjust spawn weight or damage multiplier settings to preference
- Interactable mods not spawning new content in runs Stage spawn tables may need a run restart to register new content after installation. Start a fresh run rather than continuing an existing one after installation
Companion and Drone Mods
Companion and drone expansion mods add new purchasable allies, modify existing drone behavior, or introduce entirely new support unit types. They add a strategic layer to item purchasing decisions that the base game handles only minimally.
These mods pair well with item expansion packs and produce run variety that extends engagement with the game significantly beyond the base content ceiling.
How New Survivor Mods Expand the Game
New survivor mods are the most technically complex category in the Risk of Rain 2 mod ecosystem. A high quality survivor mod includes a complete moveset, passive abilities, custom animations, voice lines or sound design, achievement integration, and balance testing against the full item pool.
The gap in quality between the best and worst survivor mods is wider than any other category.
What Separates a High Quality Survivor Mod
Before installing any new survivor mod, evaluate it against these quality indicators:
| Quality Indicator | What to Look For | Red Flag |
| Visual quality | Custom model matching base game art style | Reused or mismatched asset quality |
| Moveset depth | Unique passive and four distinct abilities | Reskinned base game abilities |
| Balance | Comparable power level to base survivors | Massively overtuned or undertuned output |
| Maintenance | Updated within two months | No update since a major game patch |
| Community reception | High rating with substantial download count | Low rating with unresolved bug reports |
| Dependency health | Clean dependency list with current packages | Outdated or abandoned dependency packages |
Recommended Survivor Mod Categories
Rather than listing specific mods that may become outdated, the following categories represent the survivor mod archetypes with the strongest community track records.
Character ports from other games
Some of the most technically impressive survivor mods port characters from other Hopoo or third party games into Risk of Rain 2 with fully realized ability sets. These tend to receive sustained maintenance due to their dedicated audiences.
Original character concepts
Community designed original survivors built around unique mechanical concepts rather than ported characters often demonstrate the highest design integration with Risk of Rain 2’s systems. Abilities designed specifically around the item pool produce synergies that feel intentional rather than coincidental.
Expanded lore survivors
Mods that add survivors from Risk of Rain 2’s extended lore and universe fill narrative gaps that the base game leaves unexplored. These tend to attract players interested in the game’s worldbuilding alongside the gameplay.
How Difficulty and Multiplayer Mods Extend Longevity
The base game’s Eclipse difficulty system provides substantial challenge for dedicated players, but the modding community has developed additional difficulty frameworks, challenge conditions, and multiplayer enhancements that extend the game’s longevity significantly beyond what the base content supports.
These mods target players who have exhausted base game content and want structured new challenges rather than simply more content to encounter.
Difficulty Expansion Mods
Difficulty mods that extend beyond Eclipse 8 represent the highest challenge tier in the Risk of Rain 2 mod ecosystem. They modify enemy scaling, spawn rates, elite frequencies, and sometimes introduce entirely new failure conditions.
Key considerations for difficulty mods:
- Confirm the mod is balanced against the current game patch as difficulty scaling mods are particularly sensitive to game balance changes
- Read the full description for any new mechanics or failure conditions introduced so they are understood before being encountered unexpectedly mid run
- Test difficulty mods in a dedicated profile rather than the primary stable profile to evaluate balance before committing to full integration
Multiplayer Enhancement Mods
Base game Risk of Rain 2 supports up to four players. Several mods extend this to higher player counts with compensating enemy scaling adjustments.
Higher player count mods require all participating players to install matching versions. They also increase system load substantially at late game stages and should be tested on the hosting system before committing to extended sessions with larger groups.
Lobby and session quality of life mods add features like character selection timers, ready checks, and between stage pause functionality that improve the cooperative experience without altering game balance.
Frequently Asked Questions
Do mods disable Steam achievements?
Some mods disable achievements while active. Check individual mod descriptions on Thunderstore for achievement compatibility notes before installing.
Can I use these mods in multiplayer?
Yes, if all players run matching mod lists and versions. Use R2ModManager Plus profile export to share exact mod lists across all players in the session.
Will mods break after game updates?
Possibly. Game updates can break mod compatibility. Check Thunderstore for updated releases after each game patch before launching a modded session.
Do survivor mods work with all items?
Quality survivor mods are designed to work with the full item pool. Check community reviews for reported item interaction issues before committing to a specific survivor mod.
How many mods is too many?
No fixed limit exists. Practical stability degrades as mod count increases. Starting with ten to fifteen focused mods produces more stable results than installing fifty simultaneously.
Are these mods safe to download?
Yes, if downloaded through R2ModManPlus from the official Thunderstore repository. Avoid downloading mods from unofficial third party sources regardless of how legitimate they appear.
Can mods be used with the Seekers DLC?
Compatibility varies by mod. Check each mod’s Thunderstore listing for explicit Seekers of the Storm compatibility notes as that expansion changed core game systems significantly.
What if a mod causes crashes?
Disable the most recently added mod first and relaunch. If stability returns, that mod is the cause. Check its Thunderstore listing for known issues or an updated release.
