User Summary Power of Defense is a sort of Tower Defense game for up to two Players. Essentially you buy robots which will then be sent over an assembly line to the end. Each robot who makes it to the end will damage the opponents base. But beware, as your opponent will summon robots himself which will then be sent over another assembly line next to yours. On their way they will battle each other to they death. Whoever buys the robots in the most efficient and intelligent way will get through to the opponents base.
