Complete guide for Human: Fall Flat Test Chamber level, featuring portal platforms, laser sensors, gravity chambers, and achievements.
1. Level Overview
Test Chamber is a high-tech experimental facility testing wobbly doll physics against spatial portals, laser logic gates, and momentum accelerators.
2. Walkthrough Steps
Section 1: Spatial Portal Placement
Pick up the portal generator cube and drop it into the socket to open a spatial portal between Test Chamber Alpha and Beta.
Section 2: Laser Logic Gates
Reflect laser beams through 3 optical prisms to satisfy the AND/OR logic gate requirements on the security bulkhead.
Section 3: Momentum Accelerator Ramp
Fall from a high ledge into the momentum accelerator portal to gain terminal velocity and shoot across the void into the observation room exit.
3. Speedrun Momentum Skips
Infinite Momentum Loop: Loop between the top and bottom portals 5 times to gain infinite velocity, then angle your exit trajectory to fling straight over the observation room wall!
4. Achievements Guide
- Thinking with Portals: Complete Section 1 without placing the portal generator cube incorrectly.
- Speed of Sound: Reach maximum momentum in the accelerator ramp portal loop.
