4. 7 Days To Die

Watch: 7 Days To Die Gameplay

The perfect blend of FPS, survival and horror. Not to mention RPG, crafting systems and characters that set the precedent for all games that came after it. It’s set in a devastated, post apocalyptic world.

Keep your frost covered baseball bat at the ready, as you navigate your numbered days. Dig through gutters, filled with filth, just get that one item that you need so desperately. Focus on crafting those hard earned items, so your efforts don’t go to waste.

 Look out for Dogs as you stroll around the city, and equip a ranged weapon for them.

7 Days to Die was built on the Unity Engine.

As you survive every seven day horde, they get bigger and more difficult to deal with. Plan for this.
