Haven't been using many guides, but this baseline has been coming along great with a sword and songbird to catch anything that may survive a missle and pistol barrage
The image is a screenshot of my AC from Armored Core 6. It's a reverse jointed AC, with the frame painted in purple and green similar to Evangelion's Unit 01, while the weapons are painted in red, black, and gold
Here's my current build:
Unit
Right arm: DF-GA-08 HU-BEN Gatling Gun
Left arm: Vvc-770LB Laser Blade
