Onslaught Tower Defence is a popular survival-based tower defence game where you stop various kinds of increasingly stronger creeps from reaching Area 51 for as long as possible. You can achieve greater firepower by forming "combos" with different towers with fully upgraded damage, close together. Upgrades, support towers and combos are essential in keeping the creeps at bay.
