If you’re a fan of high-octane platforming, frame-perfect inputs, and communities built around digital fossils, seek out this build. Just remember: once you master the Frame 180 glitch, no other platformer will ever feel fast enough again. Have you played Speedrunners build 18052020? Share your best time on the #Build1805 Discord leaderboards, and be sure to verify your recording includes the on-screen FPS counter—otherwise, your run won’t be accepted.
The build number 18052020 was originally a timestamp left in the source code by an anonymous developer (known only as V0idStrider ) who created a custom engine demo for a speedrunning competition on the now-defunct EnGaming forums. The challenge was simple: build a 2D movement sandbox where top speed was limited only by the player’s input precision. Unlike the official SpeedRunners game, which balances competitive play with items and stage hazards, build 18052020 strips everything away. It is raw, unadulterated momentum. Here are the core features that define this mysterious build: 1. Infinite Momentum Stacking In most platformers, there is a terminal velocity. In build 18052020, there is none. By chaining a specific sequence of wall-jumps, slides, and grapple-cancels (a technique known as the Phantom Boost ), players can accelerate indefinitely. Speedrunners have recorded speeds exceeding 10,000 units per second—at which point the screen becomes a blur of color. 2. Sub-Pixel Broken Collision The build’s geometry engine was intentionally flawed. Due to a rounding error in the collision detection (attributed to the build’s hasty 48-hour development period), players who move faster than 800 units per second can actually phase through thin walls. This turned any level into a non-linear web of potential "out-of-bounds" skips. 3. The "Frame 180" Glitch The most famous exploit in the build occurs exactly 180 frames (3 seconds at 60 FPS) after a slide-jump. If a player inputs a grapple command on the exact frame the slide animation ends, the game fails to reset the vertical velocity. This allows runners to "fly" horizontally for the rest of the level without touching the ground. 4. No Anti-Cheat Because this is a custom, offline build, there are no anti-tamper measures. But that’s not the appeal. The appeal is that the build was locked—no updates, no patches, no rebalancing. The version you downloaded on May 18th, 2020, is the exact same version everyone runs today. This creates a perfectly static environment for competition. Why the "Build 18052020" Community Exists You might ask: If this isn’t a real game, why do people compete on it?
The answer lies in . Mainstream speedrunning involves memorizing levels and executing precise inputs. Build 18052020 is more like a sport. It presents a sandbox with a single rule: go as fast as possible.
In the sprawling, chaotic, and incredibly niche world of competitive speedrunning, few phrases spark as much curiosity and confusion as "speedrunners build 18052020."
This article dives deep into the origin, the glitches, the controversy, and the lasting legacy of one of the most debated build numbers in recent speedrunning history. First, a crucial clarification: "Speedrunners build 18052020" does not refer to an official version of the popular multiplayer game SpeedRunners . The naming convention (DDMMYYYY format) is a dead giveaway. The date "18/05/2020" (May 18th, 2020) does not align with any major patch for the commercial title SpeedRunners , which had left early access years earlier, in 2016.
