Introduction
R2modmanager is the most widely used mod manager for Risk of Rain 2, but questions about its safety are entirely reasonable and worth addressing with clarity. Any application that installs third party software onto your computer and interacts with a game client deserves scrutiny before you trust it with your system.
The safety of r2modmanager falls into three areas: the security of the application itself, the trustworthiness of the download source, and the implications of using mods for Risk of Rain 2’s anti-cheat system. Each area carries a different risk profile and requires a different evaluation.
Quick Answer about Is R2ModManPlus Safe?
- R2modman itself is safe when downloaded from its official sources, the GitHub repository and Thunderstore
- R2modman is fully open source meaning every line of its code is publicly visible and auditable by anyone
- The application does not modify base game files, reducing risk to your game installation significantly
- Risk of Rain 2 does not use a traditional invasive anti-cheat system, meaning r2modman and most mods carry no ban risk on Steam
- Mods installed through r2modman come from Thunderstore, which has its own moderation process for listed packages
- The primary security risk is downloading r2modman or mods from unofficial third party sources rather than the official platforms
- R2modman does not collect personal data, account credentials, or gameplay telemetry from your system
- Multiplayer modding carries social risk rather than ban risk, as other players may have negative experiences if mod behavior is unexpected
- Always verify you are downloading from github.com/ebkr/r2modmanPlus or thunderstore.io before installing
Is R2ModManPlus a Safe Application to Install?
R2modman’s open source status is the strongest available indicator of its legitimacy and safety. Every component of the application is publicly hosted on GitHub where any developer, security researcher, or curious user can review the complete codebase at any time.
This level of transparency is fundamentally different from closed source applications where the internal behavior of the software is hidden from users entirely.
What R2ModManPlus Does and Does Not Do on Your System
Understanding exactly what r2modman does when installed and running removes ambiguity and allows for an informed safety assessment. The application has a clearly defined and limited scope of operation that does not extend beyond mod management functions.
R2modman reads your game installation directory to detect Risk of Rain 2, connects to the Thunderstore API to retrieve mod listings and download packages, and writes mod files to a dedicated data directory it manages independently from the game folder.
What r2modman does on your system:
- Reads your Steam library path to detect installed games including Risk of Rain 2
- Downloads mod packages from Thunderstore over a standard HTTPS connection
- Writes mod files to its own managed data directory, typically in your user profile’s application data folder
- Creates and manages BepInEx folder structures within its data directory for each mod profile
- Launches Risk of Rain 2 through Steam with modified launch parameters that point the game toward the active mod profile
- Checks for its own application updates from the GitHub releases API
What r2modman does not do on your system:
- Does not modify files in your Risk of Rain 2 Steam installation directory
- Does not access, read, or transmit your Steam account credentials or login information
- Does not communicate with any server outside of Thunderstore and GitHub for its core functions
- Does not install background services, startup programs, or system level drivers
- Does not require administrator privileges for normal operation after initial installation
- Does not collect or transmit personal data, usage telemetry, or system information to third parties
Open Source Verification and Community Auditing
The r2modman GitHub repository at github.com/ebkr/r2modmanPlus contains the complete application source code, build scripts, and release history. Every change made to the codebase is recorded in the commit history with a timestamp and description.
This means any security concern about a specific version of r2modmanager can be investigated by examining the exact code changes between releases. The Risk of Rain 2 modding community includes developers who actively monitor the repository and would identify and publicly report any malicious additions immediately.
Why open source status matters for security evaluation:
- Hidden malicious behavior cannot be obscured in code that is publicly readable
- Security researchers can and do audit popular open source tools for vulnerabilities
- Community trust is built over time through a transparent and reviewable track record
- Any attempt to introduce harmful code into a widely monitored repository would be detected and reported rapidly
- Version specific code review is possible meaning specific releases can be verified independently before installation
What Are the Trusted Download Sources for R2ModManPlus?
There are exactly two trusted sources for downloading r2modman. Every other source, regardless of how professional or legitimate it appears, should be approached with significant caution.
Unofficial download sources are the single greatest security risk associated with r2modman, not the application itself.
Official Sources and Why They Are Trusted
The GitHub repository and Thunderstore are the only verified official distribution points for r2modman. Both are controlled directly by the application’s maintainer and the Thunderstore team respectively.
GitHub provides direct access to every official release with file checksums that can be used to verify the integrity of downloaded files. Thunderstore hosts the same official releases and provides a familiar download interface for players already using the platform for mod browsing.
Why GitHub and Thunderstore are the only trusted sources:
- The GitHub repository is controlled by the application’s author and maintainer directly
- Release files on GitHub include checksums that allow independent verification of file integrity
- Thunderstore is the same platform used to distribute Risk of Rain 2 mods, making it a familiar and community trusted environment
- Both platforms have established track records within the Risk of Rain 2 and broader gaming modding community
- No legitimate reason exists for r2modman to be distributed through any other channel
Indicators of untrustworthy download sources:
- Sites that require account creation or email submission before allowing the download
- Download pages that display r2modmanager alongside unrelated software bundles
- Sites that describe themselves as mirror hosts or alternative download locations
- Any source that asks you to disable antivirus software before downloading or installing
- Pages with very recent creation dates offering older versions of r2modman as current releases
- Download links that do not originate from github.com or thunderstore.io domains
Common Problems and Solutions:
- Problem: Antivirus software flags the r2modman installer downloaded from GitHub Solution: This is a well documented false positive caused by heuristic scanning of game application installers; verify the download originated from the official GitHub releases page and cross reference the file checksum before proceeding
- Problem: A search engine result leads to an unfamiliar site offering r2modman for download Solution: Do not download from it; type the official URL directly into your browser rather than clicking search engine results for mod manager downloads
- Problem: A Discord server or Reddit post offers a modified version of r2modman claiming additional features Solution: Modified versions of r2modman from unofficial sources cannot be verified; use only the official release from GitHub or Thunderstore regardless of claimed additional features
- Problem: The official GitHub download page is temporarily unavailable Solution: Wait for service to restore and download from GitHub when available rather than seeking an alternative source during the downtime period
- Problem: A site claims to offer a newer r2modman version than what appears on GitHub Solution: The GitHub releases page is the authoritative source for version information; any site claiming a newer version than GitHub lists is distributing unofficial or modified software
Verifying an R2ModManPlus Download Before Installing
Even when downloading from an official source, a brief verification step adds a meaningful additional layer of security. GitHub provides SHA256 checksums for release files that allow independent confirmation that the downloaded file matches the official release exactly.
Step by step download verification process:
- Download the r2modman installer from the official GitHub releases page
- Locate the checksum file provided alongside the installer on the same release page
- On Windows, open PowerShell and run Get-FileHash followed by the path to the downloaded installer file
- Compare the output hash value against the checksum listed on the GitHub release page
- If the values match exactly, the file is unmodified and safe to install
- If the values do not match, delete the downloaded file immediately and re download from the official source
Does R2ModManPlus Trigger Anti-Cheat or Risk a Steam Ban?
This is the most frequently asked safety question from players new to Risk of Rain 2 modding. The concern is understandable given that some games use invasive anti-cheat systems that flag mod managers or modified game files automatically.
Risk of Rain 2’s anti-cheat situation is significantly more permissive than many other online games, and understanding the specifics removes unnecessary concern for most players.
Risk of Rain 2 Anti-Cheat and Modding Policy
Risk of Rain 2 does not use an invasive kernel level anti-cheat system such as Easy Anti-Cheat or BattlEye in a configuration that targets modding. The game has a long established history of community supported modding that Hopoo Games, the original developer, actively encouraged during development.
Gearbox Software, which acquired the game from Hopoo, has maintained this modding friendly stance. The Thunderstore platform and r2modman operate with implicit community acceptance and no documented cases of Steam bans issued for using r2modman or Thunderstore mods in standard play exist within the community record.
Key facts about Risk of Rain 2 and anti-cheat:
- Risk of Rain 2 does not use a kernel level anti-cheat that would flag mod managers or BepInEx
- BepInEx, the framework r2modman installs for modding, is widely used and community accepted
- No documented Steam ban cases exist for using r2modman or Thunderstore mods in standard Risk of Rain 2 play
- Steam achievements may be affected by certain mods depending on how they interact with the achievement tracking system
- The Start vanilla option in r2modman launches a completely unmodded game when achievement preservation is a priority
- Hopoo Games publicly acknowledged and supported the modding community during active development
Multiplayer Modding Considerations
While ban risk from anti-cheat is not a meaningful concern for r2modman users, multiplayer modding does carry social and compatibility considerations that players should understand before joining other players’ sessions with mods active.
Risk of Rain 2’s multiplayer is cooperative and the modding community has established norms around which mods are appropriate for shared sessions and which should be restricted to solo play.
Multiplayer modding best practices using r2modman profiles:
- Create a dedicated multiplayer profile in r2modman containing only mods that all players in the session have agreed to use
- Communicate with other players before a session about which mods are active in your current r2modman profile
- Avoid mods that provide significant gameplay advantages in sessions with players who are not running the same mods
- Use r2modman’s profile export feature to share your exact mod configuration with friends before multiplayer sessions
- Switch to a vanilla launch or a minimal mod profile when joining public lobbies with unknown players
- Client side visual and audio mods generally do not affect other players and carry the lowest multiplayer compatibility concern

Frequently Asked Questions
Will using r2modman get me banned from Risk of Rain 2 on Steam?
No documented cases of Steam bans for using r2modman or Thunderstore mods in Risk of Rain 2 exist within the community record. Risk of Rain 2 does not use an invasive anti-cheat system that targets mod managers or BepInEx, and the game has a long established history of developer supported community modding.
Is r2modman spyware or does it collect my data?
No. R2modman is open source and its network communications are limited to downloading mod packages from Thunderstore and checking for application updates from GitHub. It does not collect personal data, account information, or usage telemetry. The open source codebase can be reviewed by anyone to verify this independently.
Can r2modman damage my Risk of Rain 2 installation?
R2modman does not modify any files in your Risk of Rain 2 Steam installation directory. All mod files are stored in r2modman’s own managed data directory. In the unlikely event r2modman’s data directory becomes corrupted, your base game installation remains unaffected and can be launched cleanly through Steam or r2modman’s Start vanilla option.
Does r2modman require administrator privileges?
Initial installation may prompt for administrator access depending on your Windows configuration. Normal ongoing use of r2modman for browsing mods, installing packages, and launching the game does not require administrator privileges after installation is complete.
Are mods downloaded through r2modman from Thunderstore safe?
Thunderstore has a moderation process for listed packages but cannot guarantee the safety of every individual mod. Stick to mods with large download counts, positive community ratings, and recent update activity. Read mod descriptions and CurseForge or GitHub pages for individual mods before installing unfamiliar packages.
Does r2modman affect Steam achievements in Risk of Rain 2?
It depends on which mods are installed and active. Some mods may affect how achievements are tracked or unlocked. Use r2modman’s Start vanilla option to play without any active mods when Steam achievement preservation is a priority for a specific play session.
What should I do if my antivirus flags r2modman during installation?
Verify that you downloaded r2modman from the official GitHub releases page at github.com/ebkr/r2modmanPlus and cross reference the file checksum against the value listed on the release page. False positives from heuristic antivirus scanning are common with game application installers. If the checksum matches, the file is unmodified and the flag is a false positive.
Is it safe to use r2modman in Risk of Rain 2 multiplayer sessions?
From a ban risk perspective yes. From a social and compatibility perspective, always confirm that other players in your session are running the same mods before starting a multiplayer game.
Use r2modman’s profile export feature to share your exact mod configuration with friends and maintain a dedicated minimal mod profile for sessions with players whose mod setups are unknown.
