Try building here. Fairly easy. You can build a 2D skeleton and come back to the steps and finish it or something as well.
Supplies
Pretty standard things that you need, really.
Now Build Here!
Once again, pretty easy.
Here!
Right at the front, you wanna build that. Once again, quite straight-forward. As for the big yellow plate in the middle, you can switch it out with a wheel or some other large flat thing if you don't have it.
Done!!
Neat, huh? Spin the big wheel in the middle! Well, it doesn't really shoot, but try modding it to do that if you want. You can experiment with switching parts out, and all that. Enjoy!
