PixelJunk Monsters is an tower defense-style strategy game, from Q-Games, free to play now on Facebook.
Throughout the game, the player will guide a small character trough the forest, defending his tribe of helpless creatures. In Pixeljunk Monsters your objective is to construct a series of towers in a certain environment and attempt to end off attackers from reaching your base. Each monster that gets through your defenses will kill one of your tribe. You have control of the battlefield through the hands of a single character, and manage three primary resources: trees, coins and gems. Can be build any type of tower (including ones that launch arrows, fire cannon balls and even shoot lasers) on any tree on the field. It's a quite good game, and the players will not be disappointed.
