Insect Armageddon also adds a new aspect to the Earth Defense Force series that was born in Japan, with additional elements for all EDF soldiers to experience. Players can now participate in Campaign mode via online co-op for up to three players, or grab a friend and play in split-screen against the insects and aliens across a completely destructible city. Every EDF soldier can collect over 300 weapons and can choose from four upgradeable armor sets including the vaunted Jet Armor for battles on the ground and in the air. Players will engage in nonstop arcade action that is the fastest and deadliest in the series against a seemingly unstoppable swarm of insects and giant alien invaders.
In addition, the game also features a six player Survival mode that pits a human squad against a nonstop onslaught of the largest enemies the aliens have to offer. New Detroit's giant bug problem is unavoidable, and mankind's last hope lies with the Earth Defense Force. Defend the world from the insect invasion, even if it means blowing up the entire city as part of the extermination process.
