Finally unlocked the 4th slot in Factory.

So far still no luck with a 5* being build, but got two new 4* TD, both very pretty as far as the design and art style go. Though I dont see much use in them due to each costing 5' while the ones I use are fairly solid and cost only 4'.
On a brighter note, my sexi Kitty Cat Tabby, brought me a 5* Emblem from her scouting. Its an offensive one, but didnt have to look at its stat yet.
