- Complete re-balance of physical parameters.
- Finishing improved.
*v.1.3 Updates:
- Re-balanced (increased) ball speed to improve finishing.
- Re-balanced GKs (slightly slower reactions and more realistic diving speed).
*v.1.2 Updates:
- Adjusted goalkeepers to more realistically parry shots rather than catching the ball. They are also now more likely to use their feet to save shots. This results in more goal mouth scrambles and a greater variety of goals scored. Like real football, having a goalkeeper with a safe pair of hands is now even more important.

What is True Grit?
True Grit is a match engine revamp designed to reshape how football is played and experienced in FM24. It is built on the belief that the default engine is unrealistic, overly fast, overly clean, and too easily optimised - producing a style of football that rewards relentless pressing, rapid passing chains, and near-perfect technical execution at a level that feels disconnected from the real game.
This mod slows the match down and reintroduces a sense of friction into every phase of play. Players take longer to react, turn, and execute actions, creating the appearance of more natural hesitation, heavier touches, and a greater sense of physical contest. The result is a game where time and space appear to matter again—where decisions carry weight, and where even simple actions like receiving, passing, or changing direction are no longer trivial.
A central aim of True Grit is to make possession more difficult to maintain. Quick, risk-free recycling of the ball is reduced, and tight passing sequences become harder to sustain under pressure. This naturally leads to more misplaced passes, contested duels, second balls, and transitional moments - mirroring the unpredictability and imperfection of real football. Teams must work harder to control matches, and technical superiority alone is no longer enough to dominate.
Physicality (but not pace) plays a much larger role. Strength, balance, and positioning are more influential in challenges, while defensive actions are given greater presence and impact. Attacking players are less able to glide through situations unopposed, and defenders are better able to disrupt, delay, and compete. The overall effect is a more grounded, hard-fought style of football where outcomes feel earned rather than automated.
The revamp also reduces the dominance of high-intensity pressing systems (or increases the vulnerability of playing in that style). Because actions take longer and players are less artificially responsive, aggressive pressing becomes more situational and less universally effective. Tactical variety improves as a result—different styles become viable, and no single approach consistently overwhelms the match engine.
True Grit does not aim to make the game harder for the sake of difficulty, but to make it more authentic. Matches are less predictable, less sterile, and more reflective of the messy, physical, and often chaotic nature of real-world football. It rewards patience, structure, and adaptability, while punishing over-optimisation and unrealistic play patterns. High defensive lines and aggressive pressing still produce goals, but now at both ends of the pitch. Attacking in this manner now comes at a greater risk.
This is a mod for players who want to feel the struggle in every phase of play - for those who believe football should be contested, imperfect, and, above all, earned. Your players will frustrate you.
Summary of Changes:
- Reduced overall player speed to lessen the reliance on pace for breaking lines and create a more realistic acceleration profile
- Narrowed the gap between minimum and maximum acceleration to reduce the overly “arcadey” feel of vanilla FM24
- Reduced differences in turning rates across jogging, running, and sprinting, improving defenders’ ability to react to attacking movement
- Adjusted ball speed to a more realistic level, limiting rapid “pinball” passing sequences and giving defenders more time to close down space
- Significantly weakened headers - fewer unstoppable bullet headers, more loose balls and second-ball situations from long play. Direct/Long-Ball football is now viable
- Re-balanced timing of defensive “do” and “receive” actions, leading to more tackles, contested phases, and turnovers
I hope this is received by the community in the spirit it was developed. As an earnest attempt to introduce a more challenging, immersive and unpredictable match experience.

If I might make a suggestion, seeing as you're so free with sharing your own. It's best for everyone if people don't let their egos get in the way of trying to improve or offer alternative experiences for the FM community. I'm not in the business of labelling myself a 'professional' modder, nor do I really think the community cares. They're just looking for different experiences. Obviously, they expect a certain standard of stability, and I'm yet to see a crash with anything I've shared, but if one is reported I will take it down.
Unfortunately, all the existing mods for FM24 fall short of what I consider to be an accurate depiction of football. I worked on this to reflect what I consider is a better depiction and decided to share with the community. That's really all there is to it. I know you guys decided you couldn't take things further than you did with Match Lab and I respect that, but it could just be we have different measures of success. I don't think a 9th tier semi-pro team should be able to pinball a football round the park like prime Barcelona. This mod addresses that (a little).
All the best!
Another thing to consider is that the the changes we made do the AI were made specifically for the changes we made elsewhere. This means using our AI changes into our mod will not lead to the results you expect. To make sure you have a mod that makes sense and all parts work in tandem, you need to adapt the whole file structure to the changes you are making to the physics file and not only changing that file. You also need to do changes outside of the simatch file that will impact what you are doing.
Edit to add that I just checked you added our files into your work. This means you have two files, with the same name, in the file. This might create conflicts because although the game might open and read the file, this means the game will have to choose which file they apply because the ones you copied from us have different information.
Edit 2: you are sharing the wrong method of installation. It is a recipe for disaster.
Good luck
Hi, how are you? I just downloaded the mod, but it's a folder and not an FMF file.
@michaelandrews you just put the whole simatch file from the download in the folder after taking out the existing fmf. The new simatch folder replaces the existing fmf.
or maybe you have an alternative to share?
Great work all involved.
