Costume Quest and Soma free on Epic Games Store, Nuclear Throne and Ruiner next

Costume Quest and Soma are the latest games to be made available for free through the Epic Games Store.

You can download both Costume Quest and Soma now through November 7.

Costume Quest is a Halloween-themed RPG from Double Fine. In it, children complete quests around their neighborhood on Halloween while wearing magic costumes.

Soma is a sci-fi horror title from Frictional Games. In it, you are trapped in an underwater facility where the machines have started to become sentient and think they are human.

Both games will be replaced by Nuclear Throne and Ruiner on November 7.

Nuclear Throne from Vlambeer is a cross between an action-RPG, rouge-lite and platformer. In the top-down shooter, humanity is extinct and mutants and monsters now roam a post-apocalyptic world. You will use radiation to mutate new limbs and abilities while fighting through the wasteland.

The action shooter Runier is set in a cyberpunk city in the year 2091. Here, a "wired psychopath lashes out against a corrupt system" in order to rescue his kidnapped brother and find out "the truth." A hacker friend helps along the way.

Both games will be replaced with new offerings on November 14.

Last week's free games were Layers of Fear and Qube 2.
