Xeno Tactic

Xeno Tactic is a tower defense game where you have to build towers to stop aliens from reaching their goal. The map is mostly open, leaving up to the player to build the alien's path by blocking with turrets (though they aren't allowed to completely block the aliens).

There are six different missions (levels), each harder than the last. Each alien that is killed gives gold to the player that can be used to build new turrets or upgrading existing ones. The player loses if 20 aliens get through the exit gate. There are six different types of turret (vulcan, plasma, sam, dca, freeze, sonic), each with unique traits. Most aliens behave the same by just walking the path to the exit gate, however there are boss aliens with much more health, slime aliens that make more aliens on death, and flying aliens that ignore the path and go straight to the exit, also being ignored by some types of turrets whilst being the only ones targeted by dca turrets.
