This looks like a title that takes the best of a number of genres and rolls them neatly into one. Marketed as "a high-stakes, dark fantasy action game", the game features the remaining remnants of a decimated Celtic army who go up against ancient gods hell-bent on your destruction.

From the trailer there's both a Diablo vibe nestled alongside a Souls-like design ethos that puts challenge at the fore. This is one of those 'out of left-field' titles that tends to carry weight the longer its out in the wild. Here's the official mantra from publisher Deep Silver and developer Clever Beans (When Vikings Attack!):

You Are The Last Hope For Humanity

The gods’ torturous rule over humanity has lasted for millennia. Bent on cruelty and suffering, they demand to be served with blind worship through an oath of fealty pledged from every man, woman and child. To those who don't submit to the gods’ will; a slow and merciless death awaits.

Experience the brutal trials of a venturous band of warriors in their desperate plight to sever the gods’ callous grip on humanity. Every man and woman who can muster a blade, having suffered the brutality of the gods’ reign for too long, will be called upon to form your clan of eight Celtic survivors and rise up to take on the legions of horrific beasts and minions that dwell in each of the gods’ hellish realms.

A personal tale emerges with every decision made. Succeed and see legends born. Fail, and watch lives turn to dust.

There are two available editions of the game in Standard and Valiant, the Valiant of which comes with Hunter's Head Gear and the Valley of the Dormant Gods DLC.

The Hunter’s Head Gear is assigned at random in each new game playthrough. The thrill of the hunt runs through the blood of the clan and it is ritual for the trophies seized to be worn proudly and displayed for all to take notice. The hides of five exclusive beasts; a wolf, bear, boar, fox and badger are fit to be worn by any warrior and shall act as an emblazoned warning to the gods that the hunt is indeed on.

The Valley of the Dormant Gods DLC further enhances the game with three new gods – in addition to the 10 already in the game – two new weapon classes, new items, new skills, overworld extras and warriors garb. The content will be released episodically as three new levels within the game in the coming months post-launch. Each level will include a new God, alongside the other bonus content.

• Three New Gods – Enter and battle your way through three new infernal god realms. Each of these uncharted hellscapes, inhabited by abominable swarms of minions, will be a gruelling test to your mettle.
  
• New Weapon Classes – Play as two new barbarous warrior types, each with their own unique death-dealing style of combat.
  
• New Items – A windfall of new gear and provisions to aid your clan in battle and turn the tides of war.
  
• New Skills – New methods of melee to further expand your warriors’ combat system and ensure the apt champion is chosen for the battle that lies ahead.
  
• Overworld Extras – As you traverse the tranquil overworld, keep your eyes peeled and unearth the hidden secrets now spread across the serene landscape.
  
• Warriors Garb – Suit up your clan in the finest battle-ready attire and headgear for extra swagger as they enter the fray.
