Discover Test Chamber’s Shrink Ray Mayhem in Human: Fall Flat

Human: Fall Flat has rolled out its latest free level—Test Chamber—on Steam, and it’s rewriting everything you thought you knew about scale, strategy, and slapstick physics. Ditch the candy-coated whimsy of July’s Candyland and the alpine vistas of Hike: this neon-lit sci-fi lab arms you with a compact shrink ray that turns puzzles into miniature masterpieces. Whether you’re sneaking through vents, stacking tiny crates, or launching ragdolls skyward, Test Chamber cranks cooperative chaos to eleven—without a single microtransaction in sight.

Shrink Ray Mechanics Flip the Script

At the heart of Test Chamber lies the shrink ray, a gizmo that reduces objects—crates, beams, even your own ragdoll—to a fraction of their size. But growth is just as critical: regrow those same pieces to full scale and watch the world transform once again. The result is a multi-layered puzzle system where an everyday pebble can become a springboard and a hulking conveyor belt can collapse into a wobbly plank. This push-and-pull of scale demands quick thinking and precise timing, forcing you to juggle two realities in every chamber.

Puzzle Examples: From Vents to Sky-High Launches

Test Chamber’s level design cleverly weaves shrink-and-grow tasks into every corner:

• Vent Slide Sequences: Shrink yourself to crawl through grated ducts, then regrow mid-slide to trigger switches above.
• Stack-and-Climb Crates: Reduce wooden boxes to pocket size, carry five at once, then regrow them into a towering staircase.
• Conveyor Catapults: Shrink a conveyor section, duck underneath, then regrow both you and the belt to launch your ragdoll colleague skyward.
• Beam Balancing Acts: Compress steel girders to reach distant platforms, then expand them into shaky bridges.

Compared to Candyland’s marshmallow bounce and Hike’s vertical cliff puzzles, Test Chamber shifts the challenge into high-tech territory, encouraging you to see every prop as both obstacle and opportunity.

Co-op Chaos: Solo or Squad

True to Human: Fall Flat’s roots, Test Chamber doesn’t hold back on cooperative giggles. Play solo or team up with up to seven friends (four on mobile) to tackle these neon test tubes. Group play introduces hilarious physics hijinks: teammates doubling as building blocks, mid-air collisions during regrowth, and impromptu rescue missions when someone gets stuck in shrink size. Communication is key—calling out when you’re about to regrow that crate can mean the difference between triumphant progress and a cascade of flying ragdolls.

Community Reactions and Speedrun Shenanigans

Within hours of launch, the Human: Fall Flat community had already hacked the Test Chamber rules. Speedrunners thread slimmed-down conveyor belts through vents, then regrow them to fling themselves across the map in record time. Forums and social feeds are bursting with custom challenges: build the tallest mini-crate monument, stage a pint-sized rescue of a downed teammate, or simply create the most absurd Rube Goldberg machine you can imagine. The lab’s glass walls have never seen so much creative chaos.

Why Test Chamber Matters for Physics Puzzlers

Test Chamber isn’t just another free level—it’s a statement. Nearly a decade after its original release, Human: Fall Flat continues to innovate its core physics engine, proving that the smallest ideas can spark the grandest mayhem. By introducing scale-shifting mechanics, the developers have opened a new playground of possibilities: puzzles become living experiments, and every world prop transforms into a potential tool or weapon. This evolution keeps long-time fans engaged while offering fresh mischief for newcomers.

Get Shrinking, Think Big

If you’ve already bounced through Candyland or scaled the peaks of Hike, it’s time to don your lab coat and fire up the shrink ray. Test Chamber is available now for free on Steam, with console support matching its PC debut. Grab your ragdoll, gather your friends, and prepare to see the world from a pint-sized perspective—where the tiniest idea can trigger the mightiest mayhem.
