First Response Mods
Our series of police simulators, the First Response Mods series, are ubiquitous in the Grand Theft Auto and Red Dead Redemption communities.
First started in 2009, by friends in school, our mods have grown to be a worldwide phenomena, downloaded worldwide by millions of players.
We’ve created a microsite, showcasing all of our game modifications in the First Response Mods series.


Lenny’s Mod Loader
Our in-house game modification loader, for Rockstar Games titles, allows developers to extend their games like never before. Unlike previous methods, Lenny’s Mod Loader loads into the engine of the game, allowing far more precise and convenient changes. LML includes the ability to also modify game assets at runtime, allowing both developers and users to test game modifications without restarting their games, which can take a while.
LML is available for Grand Theft Auto V and is the main way of modifying Red Dead Redemption 2 on PC.
Custom Development
We’ve collaborated with partners in the past, delivering police simulator tasks based off our First Response Mods for public safety, as well as collaborating with non-governmental organisations on entirely new game modifications custom to their specifications.
