Bulwark is a freeform base builder, it allows you to build freely, with the only constraints being the contours of the landscape. It is a follow up to The Falconeer which was an aircombat game about confronting darkness while trying to escape. This game is a bit more cheerful as you are trying to create a safe haven for the people of the same world, and you do so by experimenting rather than planning, go with the flow and create a mighty fortress thru happy accident.s.
