Didn't technically make it into the game - but because the Gunbot was so early, it didn't have the same faction design that later units received. This would have been its official Senkaishu livery.
Possibly the very first sheet of unit sketches for the project, the prototype Gunbot being center left. the Scorpion also ended up staying pretty similar to this first draft!
Initial blockout concept, cleaning up the super rough sketch.
Early on in production the 'final' concepts were more exploded than some of the later more fully realised concepts.
The G1 Gunbot was the very first unit I designed for Battle Aces, and really helped set the tone of the universe. While it is a fairly straightforward military design, I wanted it to still have some personality and identity.
