Will the bridge be destructible? Looks like a perfect trolling opportunity to me...
Yup, it will be. The humans have the option to destroy it so the Flood have to take a longer route. They can even destroy it while a Flood is on there, although there is not much point apart from the lols. Yeah, like I said, there is a secondary, longer route that wraps around to the same point. So a massive dick of a player can't trap the others at the spawn.
A lot of people seem interested in this so I will let you all know where I am at with it.
At the moment, I am not working on it. Because of the rocks, I have very little budget to work with. I have recently decided to scrap most of what lies beyond the images in this thread and forge it differently, using less pieces. But don't fret, I have thought of a really awesome last holdout, that I am sure you will all love.
