A Warthog from Halo. I did this one a loooong time ago, and by now its probably my oldest MOC.
About this creation
From the front, you can see that the Warthog is 7 studs wide. Wait, what?! That's right, when I was building this, I realized that if I wanted to fit 2 minifigs in the seats, 6 studs wasn't wide enough and 8 studs was just too ugly. That's why the chassis is made almost entirely of plates that overlap each other.
The turret was pretty tricky. I had to make the back much deeper to put in some pieces that would center it up. The end result was much better than I'd hoped for.
And it can fit 3 minifigs all at once! As said before, this was the whole purpose of making the car 7 studs wide. The only thing I wish I could've done was make the seats deeper so that the minifigs could sit under the roll bar instead of peeking out above it.
