Extreme Defence is another hot title you can play on your handset thanks to our Flash Emulator. The game is based on other turret de六合縢合资料fence games, yet it presentes players with a slightly modified gameplay. The main objective of the game is to defend your base from alien waves. To achieve your goal, fit your base with extra turrets, upgrade your defences, damage, range, and many more. As the game progresses, you'll encounter different types of aliens with specific charateristics whose design might remind you of the bugs from Starship Troopers or zergs from Starcraft. In the game menu, there's a possibility to change the render quality of the graphics. So, if you run this game on a slower device, switching to "low quality" is high recommendable.
