Walk mode collision not working?

[Back2TheFuture]

When you enter the walk mode a crosshair appears and you are able to walk around in the environment you created just like an fps game.

The problem is that in this mode you can walk through walls, they have no collision. It seems like only the top of an object has collision (like a floor which prevents you from falling through it)

Can you change this somewhere?

As far as I know there's no way to change this by default. Maybe someone wrote an addon?

fly mode has no collision, it only ray casts down from eye level and puts you about 1.5 blender units above a hit.

collision w/o cheats (convex hull, primitives) can be very taxing , so i imagine if they did make a collision version it wouldn't be as "plug-and-play" with some setup required on your part for each scene object.
