Onslaught 2 is a Flash Tower Defence Web Game that can be played here. In it, you face against hordes of random objects that are trying to attack the US Area 51 base.What sets Onslaught 2 apart from most other Tower Defence games is the large number of "combos" that your towers can perform. Adjacent towers at maximum power can execute a combo that does a ludicrous amount of damage to a large group of enemies, making it a key strategy to defeating opponents. Furthermore, there are also other towers that help to boost the ability of your towers.
