ExtracTD

Co-op tower defense with free-form maze building. No fixed paths, just you, your crew, and a whole lot of angry space monsters.

Become a space engineer for XTEC, a greedy interplanetary corporation. Grab your converter gun and do what you are (to some degree) paid to do: Protect a giant mining machine from hordes of angry space monsters by constructing a deadly maze of towers and traps! Complete mining missions on various alien planets to unlock additional towers and upgrades. Assemble a crew of up to four players, combine the strengths of your different towers, and always remember: We are most definitely the good guys!
