Sentinel 2: Earth Defense Free @ Itunes

Found 7th May 2010
In collaboration with OpenFeint's Free Game of the Day, Sentinel 2: Earth Defense is Free for TODAY only.

It's war, and this time it's too close to home. The Martian mission may be over, but the aliens haven't finished playing space invaders yet.

Extraterrestrial eyes have turned to a new target: they want Earth, and you're the one that has to say 'no'!
Welcome to the future of Tower Defense.

Sentinel 2: Earth Defense expands upon the acclaimed gameplay of Sentinel: Mars Defense. The action takes place across varied, lushly rendered Earth environments, and the alien assault force has grown more vicious than ever. Luckily, human turret technology has also advanced, and the ship weapons system provides a spectacular new way to eradicate invaders!


Unleash the Sentinel's incredible ship weapons system - if you've got the power to do so...
Deploy mobile attack drones to harass the enemy and augment static defenses.
Construct boosters to buff your offense, and upgrade to top-tier towers for devastating special moves!
Pit yourself against previously unseen members of the star spawned horde.
Mission mode provides quick tactical challenges. Beat a scenario to earn achievements!
