This addon doesn't need Portal 2 or Portal. The gun uses the slot 9 in TTT, what makes it have more weight than other weapons because you can't buy other shop items what are in slot 8 and you can't drop the Portalgun, to drop it you have to die. You can buy the Portal gun in the shop of the Detective, in the game mode Trouble in Terrorist Town (TTT) Edit: Now that I think of it, they could use this to get to unreachable places. But it can only latch on the Flat Surfaces. not Janky Surfaces. It also latches on to Specific Surfaces, what specifically? I don't know.
