After looking at Aylek's "Ultra Ogre", I decided to make a faster XL version, and this is what I came up with. The amount of ammo per UAC/5 is the same as in his version. I beefed up the armor on the arms. I also experimented with 4x AC/5, but decided this is a closer match. A 4x AC/5 would be yet another design. As usual, ignore the armor distribution and distribute as you see fit. As a plus, it happens to use the engine the Sleipnir comes with, so that saves a good chunk of money.
5/5, Just ran this and racked up a 700+ 3 kill game, speed and manoeuvrability coupled with high DPS is pretty effective. Thumbs up from me.
