    Physics Puzzles Puzzles require creative use of the Gravity Gloves and environment. Examples: **Pressure Plate Puzzle** (Chapter 3)

  • Result: Basin fills in 12 seconds, opening submerged hatch **Laser Grid Maze** (Chapter 11)
  • 8 laser emitters, need to reflect beams to 3 targets
  • Use 5 reflective cubes (each weighs 6 kg)
  • Optimal path: Reflect from emitter 1 to cube A (angle 45°), then to cube B (angle 30°), then target 1
  • Time: 90 seconds before alarm triggers

    FAQ **Q: What's the best weapon against the Blast Worm?** A: Use the Gravity Gloves to throw explosive barrels into its mouth after a ground slam. Each barrel deals 200 damage, so 4 barrels kill it. The Pulse Rifle's grenade launcher works too but takes 8 shots. **Q: How do I unlock the Phase Disruptor?** A: It's found in Chapter 4, inside a locked Combine armory. You need to solve a pressure plate puzzle (2 energy cells on plate) and use a stolen keycard from the previous room. **Q: Are there any missable achievements?** A: Yes, 8 achievements are missable. "No Stone Left Unturned" requires finding all 37 notes before Chapter 12, as the area becomes inaccessible. "Weight Watcher" must be done in Chapter 3's first puzzle.
