Scary! Looks like something Skynet from Terminator would build!
You can definitely build something like that with my blocks (I already made the grenade launcher for instance), plus some primitive shapes. And I see it has a light machinegun, I also have plans to build parts for that.
For the other parts I think it'll be more suited for a military vehicle/robot creation kit, perhaps I can work on something like that after finishing the current kit.
