I’ve already played through portal multiple times, but I’ll use this to talk about the very creative Bonus Maps included in the Xbox version (now on switch). There’s not much to say other than these maps are on par with the original game. One of my favorite maps had you going up into a cube dispenser tube and having to push the clogged cubes out. There was also a few stealth ones, one in which you are having to advance around some turrets while on a moving platform. Another map had you quickly placing portals to escape gradually smaller rooms in which each room had a spiky ceiling being lowered down to crush you. It’s a shame these bonus maps aren’t even on steam.
