If EDF 5 isn’t tough enough for you then D3Publisher has the answer with Additional Mission Pack 1: EXTRA Challenge.
This new DLC pack throws various insectoids at you from the high-level missions, but also new aliens with arms and weapons as well. It sounds absolutely terrifying!
The Additional Mission Pack 1: EXTRA Challenge gives you more than 10 Ultra Hard missions to contend against, while adding over 30 new weapons and arms to try and make your path through the invading subspecies a little easier.
Earth Defense Force 5 is now available on PS4, and the EXTRA Challenge DLC can be picked up here for £5.79!
