yeah,
I'm still trying to figure out why the game is named "The Conduit" too.
1. The 'portals' which the aliens come through into our world (the ones that we have to destroy to stop the influx of aliens in the levels) are called 'conduits' in the game.
2. "The Conduit" could refer to the means in which the aliens have infiltrated and taken control of our governmental/authoritative infrastructures for the purpose of domination of our world. In which case the entire plot of the game is for us to discover what this conduit is and how we will go about severing it to stop the aliens from taking over. This is just out of speculation on my part of course.
