I am making a Portal 2 Map seires called Portal Labs And it starts off with you starting the powerup for glados again and she makes you do tests all again i want some ideas please. I dont know if i should post this here but i use hammer to make the maps.

What type of ideas are you looking for? Puzzle Ideas, Story Ideas, mechanic Ideas, or something else?

Think of some sort of twist - if your plot consists of awakening glados and testing alll over again in the exact same tests, it won't be very interesting at all !
