There is some nice stuff there but I didn't see anything that could be used without a lot of work.
Interior map assets like the holo deck/computer clusters don't really work well because our support for models in maps is not great.
The drones/droids are nice but too hi-poly. Someone would need to build low-poly versions.
The human heads are also too hi-poly, but could be used as a shortcut for baking normalmaps when the new soldier models get to that stage.
Does look like a lot of stuff available, though, so worth keeping in mind when we get a better idea of what additional aliens we'll want.
