Search online for some tutorials on using the pen tool. I am not denying it's a complex tool to learn, I still don't know how to use it properly. But I'm afraid that's how R* made their logo and there's no other way to get that result, unless you made a custom pattern and then just used the fill tool. But you'd still require the pen tool to make the pattern in the first place. PSDTuts
