Remember the guy that speedran Need For Speed: Most Wanted using Half-Life movement? Well I interviewed him and he has his sights set on some pretty big games.

"Zolika is the mad genius behind the GTA and Need for Speed Half-Life Movement Mods," Jeepy explains. Zolika made a GTA San Andreas mod that lets you rocket jump to create some serious speed. "Eventually, Zolika joined our community and started ramping up work on the mod to make it possible to speedrun as well as adding the mixed movement."

As to how the mod actually works, one of Jeepy's moderators, Bryan, says it depends on the game. "Some games have adequate modding tools that give you enough access to the movement controller to implement Half-Life movement physics without doing a whole lot of 'special' stuff."

However, it's not always that easy, which is where modders like Zolika come in. "For some games that don't give you enough modding access, you have to inject code into the running process to get things you need (like view angles, camera matrices, position and velocity data and the ability to manipulate it, etc)," Bryan explains. "This is a pretty advanced reverse engineering effort, but some people in the community (Zolika, ScriptedSnark, Chloe) are just awesome at it."

To my great shame, I've not actually played any of the Half-Life games fully, so I didn't understand what was so special about its movement. "Half-Life 1 has bunny hopping," Jeepy explains. "It’s building momentum by strafing left and right in the air while chaining strafes together with jumps in between. What makes these mods unique is that while they include the bunny hop mechanic from Half-Life 1, they also include accelerated back hopping (ABH) from Half-Life 2 which gives you exponential speed gain between hops."

If you're thinking that sounds a bit broken, you'd be correct. "In an effort to fix bunny hopping in Half-Life 2, Valve accidentally made it to where you not only gained speed while going backwards, but the speed gained was exponentially faster than bunny hopping," Jeepy tells me. "The mix of these two movements is truly a beautiful thing. We use accelerated back hops to gain a ton of speed and then we control ourselves with bunny hopping. A lot of people have commented that it looks like how they move in their dreams."

"The closest thing I can compare it to that a casual player might understand is perhaps Mirror's Edge or Jet Set Radio; it's like the ultimate parkour game that lets you chain all these awesome movement techniques together to just absolutely fly through a game that was never meant to be flown through," Bryan explains.

These techniques combine to create some utterly wild, uncontrollable movement. One time while playing GTA 5, Jeepy became so fast that he was able to jump over most of the map in a single leap. It's a good thing these mods also disable fall damage, otherwise the speedruns wouldn't get very far.

As for what's next, Jeepy says his dream games would be something open world. "I think an open-world game like Fallout or Cyberpunk 2077 would be incredible with this type of movement. With Chloe’s new FreemanAPI project, the possibilities for Half-Life movement implementation are endless!"

Can you even imagine seeing V bunny hopping around Night City and slicing off heads with their mantis blades? Even better than a Sandevistan.

If you've now got the need for speed, you should check out some of the best speedruns ever.

I'm Issy, a freelancer who you'll now occasionally see over here covering news on GamesRadar. I've always had a passion for playing games, but I learned how to write about them while doing my Film and TV degrees at the University of Warwick and contributing to the student paper, The Boar. After university I worked at TheGamer before heading up the news section at Dot Esports. Now you'll find me freelancing for Rolling Stone, NME, Inverse, and many more places. I love all things horror, narrative-driven, and indie, and I mainly play on my PS5. I'm currently clearing my backlog and loving Dishonored 2.
