Alien Creeps TD is a traditional tower defense game where players place different defensive towers in the path of advancing enemies. Their goal is to reach your defensive zone, while yours is to get rid of all of them before they succeed.
In Alien Creeps TD, you'll have a good array of defensive towers to protect Earth from the alien attack. As usual in the genre, players can add fixtures to each tower to inflict more damage on the enemy: machine guns, missile launchers, soldiers, ray guns, etc.
In addition to normal towers, in Alien Creeps TD you can also control several different heroes. Heroes are special characters that move freely around the setting and can be a deciding force with their enormous power. You'll need to be careful with them, though, because they can die.
Alien Creeps TD is a good strategy game for Android that includes a fun campaign mode with over 20 levels. The best part: each level lasts around two minutes, the perfect time for playing a quick round anytime, anywhere.
