The fourth part of the Sentinel acquired more detailed graphics, engaging soundtrack and tells the story of a new planet and alien monsters.
As in any Tower Defense (TD), in Sentinel you have to defend the key object from the enemy attacks. In this case, such an object performs the command center, which is protected by a robot Artemis and a few laser cannons. Usually, in games of this genre rarely protected key positions, but Sentinel is an exception.
At the level is a lot of places for the towers, and you do not have to cram all his powerful armada of 5-6 points. You'll defenses with a smaller radius of action, but the rate of fire, more powerful, but with a few shots, and even zamedlyalki assistant droids.
Within each level independently tower improved depending on the number of shots made and enemies killed. But, if you wish, you can also apgredit them using coins falling out of enemy aliens.
Over time, the number of tracks that are suitable to the building increases, and you become more and more difficult to control gameplay. If you suddenly become bored, I advise you to increase the complexity with easy to hard, imaginary feeling of lightness immediately evaporate.
