Enemies are approaching in Towers of Survival game. There are 10 waves of them which you need to survive. Defend by placing towers around the maze. There are 3 types of towers you can build: laser - the fast one, v-beam - the stronger one; its beam covers all tiles above and below, therefore you cannot build anything else on its way, booster - this one makes all surrounding lasers and v-beams shoot longer and re-charger faster; you can "stack" boosters to increase total boost – each laser can be boosted up to 8 times and each v-beam up to 6 times not 8, because 2 tiles are reserved. Our base have 5 cores. Each enemy is capable of destroying one core. Without cores, we cannot survive, it's that simple. Good luck! You are our last hope. Enjoy playing this game here at Y8.com!
