Portals: Difference between revisions

The portals have had several changes in design before the release of [[Portal]], as is evident in some trailers and screenshots. <ref>[http://www.youtube.com/watch?v=TluRVBhmf8w portal orientation video 1] on YouTube.com</ref> Additionally, the Orange protal used to be Red, like [[P-Body]]'s secondary-fire portal in [[Portal 2]].

* '''Portal boosting''': A player is able to boost their momentum when travelling through two portals placed on the floor by using their primary or secondary fire key as they exit the primary or secondary portal, respectively. This is caused by the Portal mechanic ''pushing'' the player away from a portal if the portal is re-placed somewhere else (or in this case, in the same place.)
