Jumping constantly is faster than walking, and since this chamber involves so much walking on non-portalable surfaces, it comes into use here. You will definitely need to shoot a portal on the first pellet’s scorch mark and take advantage of the fact that you can use it twice. After that, it’s about getting just enough faster to get an earlier pellet. Use quick save and load when you’ve gotten to certain hard achievement points. | |||

;Gold at 1 minute, 27 seconds (87 seconds) | |||
To give an idea of the speed required for this achievement, you should be at the top of the stairs with your cube, ready to jump down the halls, about 20 seconds in. For those stairs, if you jump backwards off the cube, you will be able to grab the cube as you jump and continue. | |||
After you’ve made it to the main platform area, shoot the other portal on the angled wall. Continue with the cube into the small room with the third pellet launcher (this should happen around 40 seconds in). Hit this pellet in, and backtrack, heading towards the two-button room. In the process, the pellet will come through your portal and activate the second platform. Shoot a portal on the extended, ground-level platform, and hurry quickly to put the cube on the button. You can just reach the floor-level button in time for the pellet to travel through, and then go grab the cube. At this point you should be just under a minute in. | |||
Quickly jump back to the entrance to this side room. Drop the cube, shoot a portal above the first raised platform, and another just in front (or to the side) of the cube. Grab it and jump on through. Hurry to the end and drop the cube on the button (at around 1:12). Press the small button, grab the cube, toss it in, and exit for the gold achievement! | |||
