Would Portal TFC be cool?
Hmm, indeed, some kind of shortcut would be nice, the only problem is that, once they get known, everyone's gonna use them, so they also need to be balanced in some way.
i'll try to get what i'm saying explained better next time as well
the passageways wouldn't be really easter eggs because they would be found so fast, they would just be parts of the maps. it would be better to require a team to complete a puzzle though, before they may use what the behind the scenes places contain. the whole point of the behind the scenes thing would be to add game play to the map as well as give the maps the ever-so-needed portal feel to them.
also, another game play style would be like the dustbowl map from TFC, where one team attacks and tries to move their flag to the next capture point, and one team defends and tries to stop the other team.
