Penguins keep coming and coming. Strategically place towers around the incoming route and destroy them all before they reach the end of the path or you will lose lives. Penguins Attack 4 is somewhat different because when you try to place the tower you can see the possible route the penguins will take. So make sure they are within the reach of your towers. Also, every time the penguin is destroyed he leaves some gold behind. Just hover over it with your mouse to collect it because you need it to buy new towers. Also make sure you have the skies covered because the flying enemies are flying strait to the exit, regardless of the ground path. You can call the next wave early if you feel you can keep those pesky penguins under control. The game has been sponsored by ArmorGames.
