Spacey, set-up a portal pointing at the box tube. Go back to the rocket sentry room. Set a portal up, get it to fire through the portal. It'll break the tube and drop a storage cube to pick-up and use to get up there.
For that portion I did the same thing I did to break the glass. Use the rocket launcher to break the cube tube. I believe that this is the 'correct' way to do it. 10/10 game for me. I absolutely LOVED this game. Yes it was short, but damn FUN. Reminded me a lot of ICO.
[ QUOTE ] (***SPOILERS!) After you blow the glass up with that rocket shooting robot, there is a vent you are suppose to go through that isn't jumping height. Is there a "correct" way to get up in it? Just curious, as stacking a collection of junk from the previous room didn't feel like the right way to go... [/ QUOTE ]…
