Lair Defense for Android
Lair Defense is D&D(Dungeons and Dragons) for android..or it would be if D&D was only about dungeons and dragons and was a tower defense game.
The object of this game is to stop the enemy(s) from getting and taking back to town your dragon eggs which you mostly have 3 of.
This game has good graphics and many many levels. Speaking of which the levels are so awesome as not only does this tower defense game have a 3 star rating system for each level, but unlike many tower defense games this one lets you go back and do past levels.
Now, I must warn you that this game does place everything at a semi-high price to try to get you to buy stuff via in-app buy, but it seems like this game seems manageable without having to spend real money on stuff.
