The filenames, from left to right and top to bottom, are:
Fireextinguisher
Control
Fireextinguisher (repeated, lazy me :\)
Dropship
Laser
Shaman
Tank
Taskmanager
When I saw the tank I immediately thought of the huge monstrosity briefly seen in the first test videos of a multiplayer Darwinia. It may have been the same unit. It also seems that Shamans might have been considered as actual ingame units once upon a time. The Dropship I presume was an airborne APC, though with the APC being able to traverse any kind of terrain I guess this became moot.
Though I wonder what some of the other things were, like the Task manager, Laser, and Grenade (not shown here). Fireextinguisher would have been nice, but I wonder how it functioned ingame when first proposed.
