[Fuel-Air Explosion Superweapon]
I was doing some quality assurance work on Superweapons today and I thought it made for some nice screenshots. The first test there was nothing left of my base but the construction yard. :) The Fuel-Air Explosion is an area of effect attack. Here are the hi-res frames:   
Miranda's units can now become Veterans. There are three grades of veterancy: Veteran, Elite and Heroic. Each additional level of veterancy gives the unit a new stripe and makes units more powerful. Heroic units gain the ability to self-heal when outside of combat. Originally units gained Veteran status by doing 3 times their value in damage to another unit, but it turned out that happened after just one attack so I tweaked the values a bit. Veteran is now 10x, Elite is 20x and Heroic is 30x. We'll see how that goes.
