I don’t know what I did wrong, it’s just that when I start the blender game engine some faces are not shown, I think it’s a problem on my end (or the way I model).
I tried to optimize the model as much as I could so I deleted and re-created faces so I could shape it up with as little faces as I could.
If anyone could check it out and point out the errors in my modeling (and possibly send me a fixed version) I would be really grateful. :yes:

If its just when the BGE when running, try looking at your materials and make sure transparency is off.
Your normals are flipped. Select the offending faces the click “flip Normals” in the mesh tools bar
I checked out the file, the problem is something that happens when you model in certain way or when you join 2 faces together that both face a different direction.
To solve your problem, in the 3D view go to your, in your properties tool shelf, expand the “DISPLAY” tab, scroll down a little and check the “Texture Solid” box.
When that is checked, the transparent faces will also appear in the 3D View.
All you have to do now, is go into the edit mode, select the transparent faces, press ‘W’ and click ‘flip normals’.
That about sums it up, good luck! :spin:
Edit: damn it “Mattline1” you beat me to it 
Thanks guys, I’ll try your suggestions later 
This has been bugging me for a while…
