If you like TapDefense or Fieldrunners on the iPhone, Sentinel is a must have game. Get the Lite version for free and try out this addictive strategy game. You’ll not regret spending your spare time with Sentinel on your iPhone. 

Theme, weapons and the enemies are all exciting. You have to keep away the enemies from entering the gate you are guarding. 

The game

You are the commander of a Dropship Sentinel and are responsible for defending a distant colony from the ugly alien hordes. Destroy the enemies as they pass through the meandering path. Placing the right kind of assault weapons at the right place, making calculated purchase of weapons are the tricks to win the battle and to gain the highest score.

There are four game modes; namely, easy, medium, hard and psycho. Start with the easy mode to get familiar with the game. The lite version features four defense towers with 40 waves (levels) in each of the game mode.

The game terminates the moment the enemies break through the second gate. The two gates are well fortified, but you have to try your best not to let the enemies come near the gate at all to keep it intact. The strength of the gate goes down with continuous banging. 

Graphics and sounds

The game is graphically rich and the audio content is really engaging. Enemies banging at the gate, the gun fire, shelling of bombs are all realistic.  I’ll switch to the paid version of the game after taming the psycho mode of the Lite version. Sentinel of all games is a well thought and excellently implemented game.
