i found it very interesting..
SMRT has launched a FREE online game called SMRT Smogbuster. This allows you to increase your chances to win one year free travel for four. The game is simple and engaging. You just need to press the arrow keys and spacebar to shoot. Control the SMRT plane and shoot the smog bubbles. Special weapons and life boost are available. At the end of each level you will need to kill the boss. There are three levels available and two more bonuses level to be launched.
Register on the pledge page first (less than 30 secs) and play the game on https://www.smrtisgreen.com/smogbuster.aspx. Enjoy!
oh yes... this game is quite fun...
Good for killing time during tutorial classes.... hope there are more such games :)
