Desktop TD is a fun flash based puzzle / strategy game where you have to protect your desktop from invaders by spending money on attacking pieces and building a maze for them to follow. Strangely addictive yet stress relieving... Just try and find out how many levels can you survive?.. I am still struck up at 'Hard' Mode.
Goal: Creeps enter from the top and from the left. You must stop them from reaching the other side or you will lose lives. You start with 20 lives, and when they are gone the game is over. Towers are used to attack creeps and also to block their path.
If you have never played a Tower Defense before try the Quick Start Tutorial.
For those new to the DTD game, here's how Rafe at CNet describes it:
Our desk is under attack by invaders coming from both land and air. Your only solution? Defend it at all costs, using tiny turrets. Fight off waves and waves of attackers that get more challenging with each onslaught. Use your victory winnings to fortify and buy more defensive units. Losing this battle means losing your humanity.
Another interesting game sure to make you addictive. If you want to scold somebody for introducing this game(that made you to lose precious time), put a word in "Desktop Tower Defense 1.5 leaves the building" who introduced the game to me. :)
P.S: You can't download Desktop Tower Defense offline - the Flash swf file requires an active net connection.
