Onslaught 2 is the second version of this great tower defence game where you need to defend your base from oncoming bugs and other evil attackers. First you need to pick a difficulty level and the map that you want to play. Then build turrets towers next to the road where the invaders will approach because you cannot build the towers directly on the road or on your base. Think carefully as to where you place your towers to get the best shooting position while the enemies just keep coming. Upgrade your towers as fast as you can when you have collected enough cash. Try to kill all the attackers before they reach the base because you only have ten lives and if an attacker reaches your base you will lose one of your lives.
