Well, first of all, I'd like to take this first line of my post to say: HOLY SHIT!
Then, I'd like to beg for instructions on how to make:
1. Most of your mounted guns.
2. The ATV.
3. The barrel turret thing. It's just awesome.
All three will be built, modified and used, with given credit of course. I also like the Sand Puma, but wont bother with anything other than the turret on it. I'll incorporate it somehow. If you could make the instructions, much obliged.
