The mcv for the new side is amphibous cause it hovers.But its gonna cost 3400$ instaed of 3000$.The basic unit is gonna look like C-3PO but it will look scarier.Its weapon will be called a gauss rifle that disintagrates metal and vaporieses flesh.It wont be that powerful though.When it kills an infrantry unit it will melt like using radaition.It will also self heal and is immune to dogs but not terror drones and crushing.They will be called "Necron Warriors".By the way,Im not createing this from srach.Im coping this from a game called "Warhammer 40,000".Its a table top game made by Games Workshop.Ill give you the link.
