Entry/Exit Designs For Your Base

[DaBigC]

Well, since Factorio has walls but no doors, what have you guys come up with in order to leave and enter your base without having to tear down a bit of wall every time?
I'm sure there are plenty of others who have thought of a tower defense like setup as shown in the picture, although I'm not even certain that works. Have you guys come up with anything more interesting?

I did early on.




Then I realized biters are stupid so I just leave holes...granted I use more turrets.

Yea I have noticed they do tend to throw themselves at the same part of a wall over and over, even if there is a hole nearby. There AI could use a bit of work I suppose. But it would be cool to have a nice doorway.

Then this is closest to gate I've ever had.

Even huge holes you can easily get away with, biters have no intelligence scripts.
