I just got done with some of my "Single Portal Gun" levels in my MapPack and realized how many advantages there were to having the portal gun just focusing on one portal. An example would be going through a fizzler and only the portal that came out of the portal gun would disappear and the Prop_Portal would remain unaffected.

I realize some people have already posted some maps in which only uses a Portal Gun that fires only one portal, but I think some more interesting things can be done with it.

What do you people think about it?

Agreed. I think I have only played one 'good' single-portal maps. I think it was monoportals or something like that. Need more.

BluePortals was a good one, but thats a mod, not really a map. it was really good though, although i suck at solving those.

Blue portals :3

You know, I always thought it was strange that, with all the new concepts they added in Portal 2, they never did anything to try and mix up the core portal concept a bit. Examples might be: fizzlers which only de-activate one colour portal, targets which require one portal to be open on them for certain mechanics to work (I think there was a map demonstrating this a while ago called "Portal Buttons"), or elements which behave differently depending on which colour portal they interact with.

I think puzzles which limit you in the way which you can place portals could possibly work even better than puzzles in which you can only control one portal, by causing you to think twice before placing anything. It'd probably suit Portal 2's "puzzle-box"-style chambers quite well.

oh god, why is puzzle such a silly word? it sounds like some ridiculous breed of dog

I agree with that completely nuclearduckie. walls that could only support one colour portal and the like could make some amazing puzzles. and yes it is a ridiculous word come to think of it.

I think the main reason why there are a limited amount of gameplay mechanics is because the players might not find it fun. That is what portal 2 is about, fun. After all it is a game.

Introducing too many elements may confuse or frustrate some people, therefore I believe that creating something like this would be for more advanced players rather than for everyone. (Though whoever downloads custom portal maps perhaps want a challenge)

• Yes I would like to see more good 1 Portal gun maps as mentioned previously here
