What is MrAntiFun?
MrAntiFun is a long-running community site for free PC game trainers, cheats and mods. Its core is a forum where MrAntiFun publishes trainers for specific games, alongside sections for requests, donor requests, troubleshooting and general gaming talk.
The main areas break down like this:
- Game Trainers — published trainers for individual PC games, each with its own discussion thread.
- Game Trainer Requests — an open board where members ask for trainers for games that don't have one yet.
- Donors Trainers Requests — a separate request area for donors.
- Game Trainer Support — help when a trainer doesn't work with a particular game version.
- General Gaming — general discussions, programming talk, game recommendations and site suggestions.
For a typical visitor, the practical use is straightforward: you're stuck on a boss or want to skip grinding in a single-player PC game, you search for that game's trainer, and you read the thread to see whether it matches your game version and whether other users report it working. The request boards matter if your game isn't covered — that's where you ask, and where you can see how many other people want the same thing.
A few trade-offs are worth knowing before you rely on it. Trainers are tied to specific game builds, so a patch can break one until it's updated; the support section exists precisely because of this. Availability is uneven — popular titles get trainers quickly, niche ones may sit as open requests. And since these are third-party executables, you're trusting an unofficial download, so scan files and prefer the site's own threads over reuploads elsewhere.
If you're deciding whether it fits your situation: use it for single-player games where you want to adjust difficulty or skip repetition, and avoid it for anything online or competitive, where trainers typically violate the rules and can get your account banned.
As a next step, search the trainer list for the exact game you're playing, then open its thread and check the most recent replies for your game version before downloading.
Are MrAntiFun trainers safe to use without getting banned or flagged by anti-cheat?
No — there is no way to guarantee that. MrAntiFun is a long-running source of free PC game trainers, but the site itself does not control whether a given game's anti-cheat detects a trainer. Safety depends on the game, the anti-cheat it uses, and how you use the trainer.
How to think about the risk
| Situation | Practical risk |
|---|---|
| Single-player game, offline, no anti-cheat | Very low for bans; main risk is save corruption or crashes |
| Single-player game with online leaderboards or cloud saves | Moderate — some publishers flag modified saves or stats |
| Co-op or multiplayer with anti-cheat (EAC, BattlEye, VAC, etc.) | High — trainers are exactly what these systems look for |
| Competitive multiplayer | Highest — assume a ban or hardware flag is possible |
Practical next steps
- Check the specific game's anti-cheat. If it uses kernel-level protection or is primarily multiplayer, do not use a trainer there.
- Play offline or in a private/solo session where the game allows it, and back up your save first.
- Read the forum thread for that trainer on MrAntiFun — other users often report crashes, version mismatches, or detection issues for specific games.
- Keep the trainer and game updated to matching versions; outdated trainers are a common cause of instability.
If your main concern is account safety in an online game, the safe answer is to skip trainers entirely. For single-player titles where you just want to skip grinding, a trainer is usually fine as long as you stay offline.
How do I install and use a MrAntiFun trainer for a specific game?
Go to the game's trainer page on the site, download the file, then run the trainer as administrator before or during the game. Most MrAntiFun trainers work by hotkeys, so you press a key to toggle each cheat.
Typical install and use flow
- Find the trainer for your exact game and version on MrAntiFun — search the trainer list, or open the game's thread under "Game Trainers."
- Download the trainer file from the thread's download link.
- Extract the archive to its own folder. Trainers are usually packed, and antivirus tools often flag trainers as false positives because they modify game memory.
- Run the trainer as administrator (right-click → Run as administrator).
- Launch the game. Some trainers attach before the game starts; others want the game already running at the main menu.
- Read the trainer window's hotkey list, then press the listed keys to activate each option. Hotkeys usually toggle: press once to turn a cheat on, press again to turn it off.
Matching the trainer to your game version
This is the most common failure point. Trainers are built for a specific game build; after a game update, the old trainer may stop working or crash the game.
| Situation | What to do |
|---|---|
| Trainer says "game not found" | Start the game first, then the trainer, or vice versa — try the other order |
| Cheats do nothing | Check your game version against the trainer's supported version in the thread |
| Game crashes on activation | Disable the conflicting option, or wait for a trainer update |
| Antivirus deletes the file | Add the trainer folder as an exception, then re-extract |
If the trainer doesn't match your version, post in the "Game Trainer Requests" section of MrAntiFun — that forum exists specifically for update and new-trainer requests. For troubleshooting after it's installed, "Game Trainer Support" is the right place.
Practical notes
- Single-player only. Using trainers in multiplayer or anti-cheat-protected online games risks bans; treat that as a hard rule, not a suggestion.
- Keep one trainer version per game. Mixing versions or running two trainers at once causes conflicts.
- Save often. Even a working trainer can destabilize a game during long sessions.
- If a hotkey clashes with an in-game binding, remap it in the trainer or the game.
A concrete scenario
You want infinite health in a single-player action game you just updated. Check the trainer thread's supported version first; if it lists the older build, download anyway and test — if the health option fails, request an update in the requests forum rather than hunting random files elsewhere. That keeps you on the version the community is actually supporting.
How can I request a trainer for a game that isn't listed yet?
Go to the site's Game Trainer Requests forum and post a new thread naming the game. That is the section MrAntiFun's site sets aside for "post your requests here and we will make it happen as soon as possible," so a clear public request is the intended path rather than a private message or a comment on an unrelated trainer thread.
A useful request includes:
- Exact game title, plus edition or store version (Steam, Epic, GOG) if they differ.
- Game version or build number, since a trainer built for one patch often stops working after an update.
- Single-player or multiplayer context — trainers are typically aimed at solo play, and using them online can get your account banned.
- What you want changed: infinite health, money, ammo, skill points, speed, and so on. Specific options are easier to act on than "a trainer for everything."
- Whether a trainer already exists for a related or earlier version of the game; say so if you checked.
If you have donated, the site also shows a separate Trainers Requests For Donors section. Treat that as a faster or prioritized queue rather than a guarantee — the page lists donor request threads separately, but it does not promise turnaround times.
Practical next step: search the trainer list and existing request threads before posting, so you do not duplicate a request that is already open. If your game is listed but the trainer fails after a patch, post in Game Trainer Support instead, with the game version and the exact error, because that forum exists for troubleshooting rather than new requests.
For broader context, trainer communities such as WeMod and Nexus Mods cover overlapping ground with different models — WeMod leans on a client app with supported games, while Nexus Mods is a general modding hub. Checking there first can tell you whether a trainer or mod already exists, which is worth mentioning in your request.
What should I do if a MrAntiFun trainer isn't working or crashes my game?
Start with the game-trainer support section of the forum: that is where the community troubleshoots trainers that fail to launch, don't attach, or crash the game. Post there before assuming the trainer is broken—most issues are version mismatch, antivirus interference, or a game update that changed memory addresses.
First checks to run
- Match trainer to game version. Trainers are built for a specific build. If the game auto-updated, the trainer's addresses are stale and it will fail or crash. Look for a trainer version matching your current game build.
- Run as administrator. Right-click the trainer executable and choose "Run as administrator"; the trainer needs to read/write another process's memory.
- Add an antivirus exclusion. Trainer executables are frequently flagged as false positives. Quarantine or silent blocking is a common cause of "it does nothing."
- Launch order matters. Some trainers must be started after the game reaches the main menu; others need the game running first. Try both orders.
- Disable overlays. Steam, Discord, GeForce Experience, and similar overlays can conflict with the trainer's hook. Turn them off and retest.
- Check for a newer trainer. If the game patched, the fix is usually a refreshed trainer rather than a workaround.
If the game crashes
- Note exactly when it crashes (at launch, on activation, on a specific cheat) and which cheat triggers it.
- Test with only one cheat enabled at a time to isolate the culprit.
- Verify game files through your launcher, then retest—corrupted installs cause crashes that look trainer-related.
- If it still crashes, report it in the support area with your game version, trainer version, and the exact steps. That level of detail gets a faster response than "it doesn't work."
Where to post
- Trainer support threads: for crashes and "not working" reports on an existing trainer.
- Trainer requests: if no trainer exists for your game or build yet.
- General gaming discussion: for broader questions about how trainers interact with a game.
A concrete scenario
You update a game, launch the trainer, and the game freezes at the loading screen. Rather than reinstalling everything, check the trainer thread for that game first—someone has likely already reported the same post-patch break, and a newer trainer build may already be posted. If not, post your game build number and crash point in the support section.
Decision rule
Antivirus or version mismatch explains most failures; test those two first. If the trainer is simply outdated for a newly patched game, waiting for or requesting an updated trainer is the realistic fix rather than troubleshooting your PC further.
For official trainer downloads and the current support threads, use MrAntiFun, PC Video Game Trainers, Cheats and mods.
How does MrAntiFun compare to other trainer tools like WeMod or PLITCH?
MrAntiFun is a forum-first, download-based trainer hub: you find a trainer thread for a specific PC game, download it, and run it alongside the game. WeMod and PLITCH are client-based platforms: you install one launcher/app, and trainers for supported games are delivered and updated inside that app. The practical difference is workflow and trust model, not just "which has more cheats."
H3 Where each approach fits
- MrAntiFun (MrAntiFun): Best if you want a standalone trainer for one game, prefer browsing a forum for requests, troubleshooting and other users' reports, and don't want an always-running overlay client. Trade-off: you manage downloads yourself, and per-game compatibility depends on the trainer matching your game version.
- WeMod: Best if you want a single library with in-app toggles and automatic updates across many games. Trade-off: an account and a background client are part of the experience, and the catalogue is limited to games the platform supports.
- PLITCH: Similar client model with its own catalogue and subscription tiers. Trade-off: same account/client dependency, and availability varies by game and region.
H3 Comparison at a glance
| Aspect | MrAntiFun | WeMod / PLITCH |
|---|---|---|
| Delivery | Forum threads + direct trainer downloads | One client app with a game library |
| Account needed | Not required to browse; forum account for posting | Typically required |
| Updates | Per-trainer, tied to game patches | Handled inside the client |
| Community | Request threads, support threads, general gaming talk | In-app community and support channels |
| Control | You choose files and versions | Platform decides availability and features |
H3 Concrete scenario
You're replaying a single-player game you own on Steam and only want infinite health for one weekend. A standalone trainer from a forum thread is the lighter path — no new client, no account. If you jump between ten games a month and want toggles to just work after patches, a client platform saves more time than it costs.
H3 How to decide
- Count how many games you'd actually use a trainer for. One or two favors standalone; many favors a client.
- Check whether the specific game and version is covered before committing to any tool.
- Decide if you're comfortable running a background app and creating an account.
- For standalone trainers, verify the game version in the thread matches yours, and read the support section if it doesn't work.
Next step: search the exact game title plus your version number on the site you're considering, and look at the most recent replies — recency is the best signal that a trainer still works after a patch.
