The Darkish Souls speedrunning group has discovered an exploit that just about breaks the AI of enemies and, in doing so, cracked the sport large open.

Since Darkish Souls launched in 2011, speedrunners realized doing sure actions within the recreation’s tools menu or swapping weapons would trigger a slight delay in enemy AI. In idea, this could be useful, however in observe, it was typically unpredictable. As catalystz factors out within the video, sure bosses react in a different way to the glitch, which makes it troublesome to arrange for. In speedruns, preparation is essential, so not realizing how a boss would behave was truly a draw back to this exploit. Some would do nothing, others would do what was colloquially known as “bulldozing,” the place they’d simply run on the participant with out truly attacking. As such, many speedrunners selected to forgo opening the tools menu towards bosses they could have hassle with.

This identical phenomenon happens in the event you open the tools menu whereas strolling by way of a fog wall, which happens earlier than boss fights. Because the group regarded into this, speedrunner Kahmul found by way of the debug model of the sport that Darkish Souls retains an inner record of characters that enemies will goal that refreshes each 151 frames. The participant will seem on this record in the event that they stroll into proximity of an enemy, but when they’re utilizing these exploits, they’ll have temporary home windows the place enemies received’t understand them, they usually received’t be registered as potential targets.
When it got here to boss fights this exploit might assist with, Gwyndolin got here to thoughts. This struggle includes a boss that teleports away from the participant after which makes use of ranged assaults because the participant closes in on her new place. If an enemy is in a standby part earlier than a struggle, they’ll stay in that state till the participant is detected, which means in the event you’re utilizing the exploit, you may primarily be invisible to an enemy like Gwyndolin for a short time period. That is how speedrunners have been in a position to defeat Gwyndolin on this window earlier than she was in a position to teleport. Now that the speedrunner group has a greater understanding of this AI-breaking exploit, they’ve been implementing the tech in different boss fights.
Catalystz’s video breaks down the Gwyndolin encounter body by body, so in the event you actually wish to get into the specifics on the way it all works, you’ll want to take a look at their explainer. For the remainder of us, the Darkish Souls speedrun group is one other instance of how we’re nonetheless studying little nuances to older video games. The Mario Kart 64 speedrunning group additionally had a current breakthrough on considered one of its tracks, and that recreation is sort of 30 years outdated. Speedrunning is magic, and people with the persistence to do it are magicians.
