Tower defense fans should have no trouble warming up to HexDefense, a tried-and-true exercise in laying down fire and creating mazes to slow down an advancing enemy.

Each level of HexDefense is hexagon-based grid, through which a group of enemies race to take the shortest path to the player’s “base.” If too many of the geometrically-shaped enemies reach the base, it’s game over. So players have to spend money to set up towers that can shoot the enemies and kill them before that happens.

If you’ve played tower defense games, you’ve played HexDefense. But that doesn’t make it any less fun, and it literally morphs into new dimensions on a tablet. The simple neon art style is easy on the eyes, and HexDefense gets right the basics of the genre to make this a strong entry and worthy tablet download.
