Would be cool to have salvage options for the humans, like tank carcasses being left behind after destruction and a reclaimable salvage vehicle to clean it up and get some resources back (like supreme commander).
I’d also provide cover for infantry and smaller alien units, with possible asset denial tactics/baiting.
FPS drops would be a concern, but a few have suggested a pile of gore/scrap to represent what's left over and a timed decay as it slowly sinks into the sand and is lost forever~
Could utilize the harvester mechanics and just spawn resources spots under the tank that just died. But I'm just spit balling here.
