It's a game about building tanks. Still very early in EA but still being actively developed. They recently incorporated geometric internal design into the main branch - meaning components like the engine, gearbox etc as well as crew have to fit inside the vehicle. (although they don't actually have to be fully enclosed, you can make open top vehicles if you like)
There's like 10 scenarios to go through in different eras of tank tech from WW1 to late WW2. Plus a custom tank skirmish mode.
