Arc (tommysays)

ARC - Animal Resistance Command. You're in charge of the elite animal force protecting the last of Earth's living beings as they travel in search of a new home.

In this tower defense game, you place animals around the alien routes to protect from the invaders. 

Click the icon of a resister animal, then select placement on map. Each of the three resister animals provides a different defense. 

To win, keep at least one of the ten passenger animals alive by the end of the final round.

You'll gain coins after each round to purchase additional resister animals, as the rounds become progressively harder.

Noah's ark in space--an unlikely combination!
