Hue is a vibrant puzzle-platformer, where you alter the world by changing its background color.

With a simple color-matching mechanic as its palette, Hue seamlessly blends a vivid art style with clever level design and a touching narrative to paint a platforming adventure as refreshing as it is colorful.

Although everyone whom the titular Hue encounters sees only in greyscale, the world of Hue is far from black and white. On a journey to solve his mother’s disappearance, Hue begins to piece together her discarded research, ultimately discovering the ability to see the world’s hidden color and change it to alter reality. As the background shifts between shades, rifts form, and obstacles slip between pigmented dimensions.

As Hue uncovers new details involving his mother, he’s able to manipulate the game world in increasingly sophisticated ways. By transforming the background color of the world, Hue can manipulate objects, unlock new areas and interact with new aspects of the environment. Along the way, Hue will meet a diverse cast of imaginative characters in a witty and wonderful world filled with inventive puzzles and the tendency to instill a genuine sense of wonder. Hue also features support for a multitude of color-changing LED devices, and offers a full-blown colorblind mode by utilizing unique symbols as a color aid.

Once Hue, the current free game on the Epic Games Store, has run its course, it will be up to Killing Floor 2, The Escapists 2 and Lifeless Planet which will be gratis starting July 9 until July 16, 2020.

It was previously announced that Conan Exiles would also be free this week, but that has been removed/delayed, and all Epic Games had to say was "The Epic Games Store team has decided that Conan Exiles will not be free, but will be available for purchase on the store at a later date."

Killing Floor 2

In Killing Floor 2 players descend into continental Europe where the outbreak caused by Horzine Biotech’s failed experiment has quickly spread and gained unstoppable momentum, essentially paralyzing the European Union.

The terrifying Zeds are back, bigger, badder and bloodier than ever, in this upcoming sequel where players must survive the fallout of failed corporate experiments and the wreckage left behind.

In Killing Floor 2, players descend into continental Europe where the outbreak caused by Horzine Biotech’s failed experiment has quickly spread and gained unstoppable momentum, essentially paralyzing the European Union— Just one month after the events in the original Killing Floor, the specimen clones are everywhere and civilization is in disarray; communications have failed, governments have collapsed, and military forces have been systematically eradicated. The people of Europe know survival and self-preservation too well and lucky survivors have gone into hiding.

Not all have given up hope though... A group of civilians and mercenaries have banded together to combat the outbreak and established privately funded operation bases across Europe. Upon tracking specimen clone outbreaks, players will descend into zed-laden hot zones and exterminate them.

Armed with an array of deadly weapons, varying from pistols to rifles to shotguns and the versatile Katana – players can team up in co-op play (6 players) to better their chances for survival, or for the bravest souls who think they can survive alone, solo play is also available. Delivering on the three essential pillars of the Killing Floor franchise - Bullets, Blades and Blood - and introducing the visceral M.E.A.T. system, Killing Floor 2 will deliver the most horrifyingly intense experience ever seen in a console game. An expanded perk system – with perks from the original game having been reimagined, and further brutal melee combat – reinventing the melee combat completely, make for a blood-splattered gaming experience.

The Escapists 2

The Escapists 2 is a sequel to the sandbox prison-escape game. It features drop-in/drop-out multiplayer via split-screen or online play, and it supports up to four players in co-op and versus modes.

Escaping won't be easy though. You'll have to work around the strict prison schedule and avoid the unwanted attention of guards. Craft weapons and tools found (or stolen) from within the prison, but beware of cell shakedowns. Get a job or perform “favours" for your fellow inmates to purchase vital supplies, all while scouting escape routes.

Lifeless Planet

Lifeless Planet is a 3D action adventure that puts players in the moon-boots of a volunteer astronaut on a one-way mission to a life-bearing planet far outside our solar system.

While seeking life on a distant planet, an astronaut discovers an abandoned Russian town. He suspects his mission is a hoax until a mysterious young woman saves him from a strange and deadly phenomenon... Lifeless Planet is a third-person action-adventure that features an old-school sci-fi story and spectacular environments in the spirit of classic action-adventures.

After a hard landing on the planet, the astronaut discovers the planet that was reported to be rich with life is instead a barren wasteland. When he goes searching for his crew, he makes a more startling discovery: evidence that humans have already been to this planet years ago! When he comes upon a deserted Soviet-era Russian town, he struggles to make sense of his mission. Did his light-speed travel to the planet send him back in time? Or is this all some strange Cold War hoax?

Along the way, the astronaut meets a Russian woman, Aelita, who is somehow able to survive the hostile atmosphere of the planet. Through an unusual natural phenomenon, the her skin causes the soil to glow green under her feet. The player must use these glowing tracks as a guide across the planet past treacherous and deadly threats. Is she leading him to safety... or an untimely death?

Lifeless Planet was inspired by Cold War era science fiction stories, posing questions about humankind's desire for space travel. What if you journeyed across the galaxy to another planet, only to find humans had already been there? What kind of person would sign up for a one-way mission, leaving behind planet Earth and everyone they've ever known and love... to go in search of an Earth-like planet?

Equipped with a limited-use jet-pack and a mobile robotic arm, the player must use wits and skill to solve puzzles, unravel the mystery, and survive the Lifeless Planet!
