It's a TD style defense game. In this speshool tower defense game, ur an elite soldier whose job is to finish all the missions ordered by the general. You need to place your troops in designated areas (tower positions) to protect your base. How is ur strategic mind? U only have a limited budget, so don't blow it on the wrong units in the wrong location... right?
Remember to use ur speshool skill things as well as placing soldiers in tower positions. U will need everything u have at hand to stop the enemy troops marching into ur base and executing everyone in sight.
