Do you know all of the horses in Murderer’s Creed 1 are constructed utilizing actually fucked up human skeletons? Or that Titan Quest used invisible squirrels as in-game timers? All of that is true and is extra proof that video games are largely wild collections of code and hope which have extra in widespread with miracles than they do with software program.

Video video games shouldn’t work in any respect. That is what I’ve realized after studying tales shared by devs about making video games and all of the tips and hacks used to get these items working. These tales of hacked-together options have at all times been round, but a recent viral tweet about invisible squirrels being used as in-game timers has led to a brand new wave of tales rising on-line that present, as soon as once more, how video video games are largely held along with tape, magic, and a few sticks.


For a fantastic instance of this, let’s start with a tweet from Charles Randall, who labored on the unique Murderer’s Creed. He shared two fascinating developer hacks about hidden arms and fucked up horses.

It seems, in Murderer’s Creed, the crew didn’t have the finances to create a particular, customized skeleton rig for fellow murderer Malik. So, when the character loses an arm, it’s truly nonetheless there, however simply inside out. Randall defined that when you clipped the digital camera into his mannequin you’d probably see a “tiny little scrunched-up arm contained in the bicep.”

One other, wilder AC1 hack entails the sport’s horses. Randall defined that horses within the recreation have been created out of “twisted fucked up” digital human skeletons rigs as a result of, on the time, the crew’s tech solely labored correctly with bipeds.

“Cheers to the wonderful animators and riggers that managed to make that man appear to be a horse,” tweeted Randall.


On Twitter, recreation developer Luke Parkes-Haskell shared a simple fix that was used in Fable: The Journey, the Kinect-only Fable spin-off launched again in 2012. In keeping with Parkes-Haskell, the crew encountered an issue proper earlier than delivery the sport.

The problem: Sure grass and water supplies wouldn’t correctly render within the recreation. As an alternative, gamers would see the sport’s default grey checkerboard textures utilized by the devs throughout improvement. However with time working out earlier than launch, the crew found out a sublime and fast repair. They only swapped out the default dev texture from checkerboard grey to flat inexperienced. Downside solved and the sport shipped.


Dark Table shared a story about how they labored at a studio the place the engineers weren’t capable of present the designers with timers or any strategy to delay triggers or sequences. They did, nevertheless, have entry to falling objects which featured physics and collision. In order that they hacked collectively their very own timers by dropping in-game bins off-screen from completely different heights to set off occasions utilizing the objects’ collision.

Whereas they didn’t really feel snug sharing the identify of the studio or the Dreamcast recreation in query, Darkish Desk shared a joke with Kotaku about testing the sport on 50hz TVs.

“I imagine the primitive physics system was frame-rate dependent,” Darkish Desk defined. “So once they first did testing on PAL TVs (50hz) as a substitute of NTSC TVs (60hz) all the timers within the recreation have been off by a bit. I believe this was truly when the engineers first found what the designers had been doing (and it was too late to vary it).”


Rolf Klischewski, a dev who labored on The Settlers III, shared how the team was able to ship the game despite massive desync problems when taking part in on-line. After spending weeks on the lookout for a repair, at some point the error message confirming a desync had simply stopped showing. In keeping with Klischewski, the CEO praised the coders for his or her arduous work. However then he revealed what actually occurred:

“Few of us knew that one among them had simply REMmed the error message.” In different phrases, somebody added a little bit of textual content to the code to make the error message go away, which doesn’t actually repair the issue, nevertheless it does allow you to ship the sport. It’s the game-dev equal of inserting some duct tape over the “examine engine” gentle in your automotive.


Artist and game developer Alex Zandra shared a story about a small motorbike recreation she made that featured roguelike development. As she informed Kotaku, her track-building system used pre-built vertical stage chunks after which positioned them collectively to create a seamless observe gamers would then race throughout. All of this occurred through the loading of the extent.

Nonetheless, there was an issue. Each single time a stage was generated, it might place an additional, unintended and huge wedge part on the very finish. Realizing that it might take too lengthy to rewrite the code to repair this hard-to-solve bug, Zandra went with a distinct, much less “elegant” hack.

“I simply left that in and as a substitute made a little bit little bit of code to destroy the odd block out,” defined Zandra.

“Technically when a stage begins that bizarre oversize ramp block is there on the finish, however fortunately it’s too far forward for the participant to see it, and my further code finds it and deletes it earlier than it even comes on-screen. Not precisely elegant, nevertheless it works!”


Typically these recreation improvement hacks will be summarized in just a few phrases or a single tweet. Nonetheless, Nate Purkeypile, a former Bethesda dev, had a more involved and wild tale of video game hackery to share in regards to the implausible Fallout 3 DLC, Level Lookout.

The issue he encountered was that at one level within the DLC, the crew wanted a mansion to blow up. Appears easy sufficient. You blow it up. In case you’ve performed the DLC, you probably didn’t suppose something of it. They blew it up and that’s that. However oh… there’s a lot extra to it. Due to how the engine in Fallout 3 labored, Purkeypile and the small group making Level Lookout have been unable to set off occasions far-off from the participant. Something within the distance you see was only a static object.

The answer to this concerned utilizing one piece of already current tech in the principle recreation: repurposing the system used to explode Megaton in Fallout 3. 

Regardless of the mansion being proper in entrance of you, Purkeypile defined to Kotaku that it “needed to be of that ‘distant explosion’ object sort” used within the destruction of Megaton within the authentic recreation. “In any other case we might simply at all times have a home there if you’re distant. So this workaround allow us to then flip off that “explosion home” (that was only a home and NOT an explosion) after the mansion truly blows up.”

Or to place it one other means, Purkeypile acknowledged: “So yeah, counterintuitively, after it explodes, we flip off the pretend “explosion” home.”

You may be questioning why the crew didn’t have the sources to create what they wanted. Purkeypile defined to me that, on the time, Bethesda was pretty small. And most folk then have been engaged on Skyrim. So the DLC groups had to determine fascinating and low-cost methods to make use of already current tech and property to unravel issues like blowing up a mansion.


Taylor Swope, a designer at Obsidian, shared how the team made NPCs appear on monitors and screens in its RPG, The Outer Worlds. It seems that everytime you see somebody talking to you on a display or monitor, the character is definitely close by in a separate room embellished to appear to be the realm they need to truly be in when sending the message.

Swope defined to me that this can be a widespread trick that may be discovered in lots of different video games. For instance, I’ve seen this myself when no-clipping and exploring ranges in Valve’s Half-Life 2.

As for why devs use this feature as a substitute of pre-rendered video information, Swope defined to me it largely comes all the way down to file dimension.

“Video information get actual huge, actual fast. So not having to incorporate them within the recreation information is a plus,” mentioned Swope.

“For video games like The Outer Worlds, there’s additionally plenty of participant interplay concerned in conversations like this, and so the sequence taking part in out on the display wants to have the ability to reply dynamically.”

“We might theoretically pre-render every response in a separate video and decide which one to play primarily based on the participant’s selections, however then you definately’ve received even MORE video information to cope with and have to construct out a brand new system only for that. It’s simpler to simply use the dialog system we’ve already constructed and seize the opposite aspect of the dialog ‘reside’.”


Recreation developer Logan on Twitter shared a simple solution to a camera issue they stored working into whereas engaged on their recreation, Go Fly A Kite. Utilizing a first-person perspective, the participant would spawn whereas seated in a bus. Nonetheless, this brought on an odd bug.

“Basically the participant would spawn in,” Logan informed Kotaku “and the participant digital camera would attempt to transfer to its ‘docked’ place on the similar time, inflicting the digital camera to do that 360-degree flip.”

Having your recreation begin with such a wild digital camera transfer wasn’t a part of Logan’s plan, however fixing it was difficult. So as a substitute, Logan merely added a pretend 2-second loading display that performs proper because the scene begins and after the actual loading display.


Lastly, Georg Zoeller defined on Fb (which was shared on Twitter with his permission) an enormous variety of wild tips and hacks utilized by completely different groups throughout a big choice of common video games. Listed here are only a few of one of the best ones they shared:

Within the MMO Star Wars: The Previous Republic, all exploding barrels are full of shrunken invisible individuals, as solely NPCs are a sound injury supply. “Sure, that’s proper, somebody is blown to bits each time you shoot an exploding barrel,” defined Zoeller.

“Oh, initially they have been advanced fashions with transparency utilized as a result of to many a designer, when you’ve got a hammer, the whole lot is a nail,” Zoeller mentioned. “I needed to write a script to search out all of them as a result of they tanked the body price fairly badly.”

Within the navy FPS, Operation Flashpoint, Zoeller revealed that the designers had “no means of constructing explosions.” As an alternative, they launched autos corresponding to tanks and vans on the floor at huge speeds to create giant explosions. Apparently, on some maps, that is how they created artillery fireplace.

Maybe the wildest one was in Star Wars: Knights of the Previous Republic, the place there was one random animal that managed a planet, principally.

“All international quest variables on a sure planet have been saved on an untargetable ambient creature,” mentioned Zoeller. “Seems AOE results might nonetheless purchase the creature and kill it, breaking your recreation when you simply occur to kill the correct ambient creature.”

Sorry, your recreation broke since you killed the God Animal of Naboo. Video video games are wonderful.
