Publisher Square Enix and developer Avalanche Studios announce JUST CAUSE 4 Los Demonios, a new expansion coming to JUST CAUSE 4 on July 3rd, or June 26th for those who own the Gold Edition with its season pass. As a translation of the title suggests, Los Demonios (the demons) will add demonic forces to the already over-the-top action game, saying this will create a completely new sandbox experience for players. They offer a new development update covering the DLC, as well as a new spring update that's now live in the game, adding lighting improvements, destructible Black Hand statues, improved Black Hand combat vehicle AI, new mobile chaos objects, and destructible metal train bridges. Here's a trailer with a look, and here are more details:

When Rico & Javi, investigate a newly discovered temple off the shore of Solis, an archaeologist working with the Black Hand unexpectedly releases an ancient demonic force from its imprisonment.

A parasitic infestation now spreads across Solis, terrorizing its inhabitants and attacking any Black Hand forces that stand in its way. Rico must tackle a horrifying new threat and seek out answers to eradicate the demon invasion from the island permanently, before it’s too late!

Discover a completely new sandbox gameplay experience with Los Demonios, as demonic hordes, pulsing tendrils and spore-filled clouds infest the towns and people of Solis in an exciting new supernatural addition to JUST CAUSE 4.

Face the demons across new missions that will require all the skills and tools at Rico’s disposal to emerge victorious. Vicious demons spit corrosive projectiles, possess soldiers, and even take over military vehicles and turn them against Rico.

Seamlessly integrating into the JUST CAUSE 4 sandbox, the new missions enhance the crazy open world experience further and provide a return to the popular liberation gameplay of the JUST CAUSE 3. Introducing new weapons and equipment to unlock, including the Demon Crossbow and Demon Egg Supply Drop, Los Demonios lets you take the new tools of destruction into the open-world sandbox of JUST CAUSE 4 for explosive new action packed moments of glorious mayhem.

“Los Demonios is the second DLC pack in the ‘Dare Devils, Demons and Danger' Expansion Pass, and it brings a totally new experience to JUST CAUSE 4,” said Bryan Rodriguez, Creative Producer at Avalanche Studios. “For the first time, Rico is tangling with an otherwordly threat that will push him to his limits. This is our chance to see if Rico is as good at squashing demons as he is at toppling dictators!”
