Testing the new V3 framework, the NEST Special Forces have rolled out the Sailia test unit. This will serve as a basis for future NEST reFrames and is currently undergoing field testing operations for evaluation and feedback. Part of the evaluation is testing the new weapon systems as the Sailia is equipped with the experimental weapons ER-YYG01XI Energy Rifle and RG-ELMARAIL Rail Cannon.

If there’s something about the mechs Omar Gonzales (a.k.a. Chokolat Shadow) builds, it’s that they’re always excellently built with an amazing color palette and a fine attention to detail. His newest mech named the Queen of Hearts is the first of a series of builds entitled “Royal Flush” and is themed along the 4 houses of playing cards.
