Japanese publisher D3 Publisher's Earth Defense Force series has always provided addictive co-op thrills. Now D3 Publisher (which has apparently been bought by Bandai Namco) has unleashed an exciting new title on PlayStation 5 and Steam called Custom Mech Wars. This one lets players design wildly inventive custom mechs and then tackle missions together in 4-player online co-op. Yeah, that sounds a lot like EDF but with even more mechs!
