Collapse It is a unique demolition game in which you not only have to destroy the building before you with high-powered explosives, but you must also destroy all of the civilians below! With each level you are given a set amount of bombs and explosives in which you must either destroy the building (with the sticks of dynamite) or kill the humans with the nukes. Collapse It is much like Demotion City, though there are several distinct differences that make both games unique to one another.
