Wow heaps of replys guys good job
Anyways as a guide it would be about as big as the bridge in half-life 2, probley as long to, 10 minutes or shorter. Its theamed in a city Called "Hexam" a fictinal city in my mod 'reddawn'. The City is huge, like much bigger than any other city in real life and I think I have pulled of this theame quite well. The Bridge is extreamly high so not many buildings are visable. There is fog to so I can have a draw distance. I just think it would be annoying for the player to run into several trigger_changelevels while on the bridge, unlike the Bridge in half-life 2 where there was like only one, or none at all I cant remember.
But I have also encounted a problem. Its night time when youre on the bridge and the fog looks terriable at night. I'm using spirit of Half-life's fog and yeah.
P.S The bridge is there to demonstrate the Large Scale of this city, is cool and would be really cool ....... runs away
