Epic is about to refresh the free PC gaming giveaways on the Epic Games Store.
As part of Epic’s bid to dethrone Steam, the company gives away a selection of free PC games each week.
Previous free games have included Grand Theft Auto 5, Borderlands, Civilization 6 and Star Wars Battlefront 2.
The current free games include two excellent retro releases, such as Sonic Mania and Horizon Chase Turbo.
Unfortunately, however, Sonic Mania and Horizon Chase Turbo will only be available to download until 4pm BST UK time on July 1.
The current freebies will be replaced by first-person puzzle game The Spectrum Retreat.
You can download The Spectrum Retreat from July 1 until July 8 at 4pm BST UK time, at which point a new game will join the line-up.
The Spectrum Retreat features a host of colour-coded puzzles in the rooms of a mysterious hotel.
“The Spectrum Retreat is a challenging, first-person puzzle game set in the near future,” reads the official description.
“You awake at The Penrose hotel, a peaceful yet unsettling refuge from the outside world. As a valued guest, your existence is embedded into the corridors and guest rooms of The Penrose.
“Exploration of the striking art-deco hotel will begin to uncover the mysteries of both The Penrose and the uncertainties surrounding your current stay. Your desire to unearth the truth is obstructed by an array of colour-coded puzzles, mind-bending physics challenges and the growing fear of exposing your true intentions.”
Undoubtedly the best game of this week’s bunch is Sonic Mania, which gives the classic gameplay a modern makeover.
“The ultimate celebration of past and future. An all-new adventure full of unique bosses, rolling 2D landscapes, and fun classic gameplay. Sonic Mania brings retro fast-paced platforming into the future through pixel perfect 2D graphics running at 60FPS.”
Finally, Horizon Chase Turbo is a racing game inspired by classics such as SEGA’s Out Run.
“It recreates classic arcade gameplay and offers you unbound speed limits of fun. Horizon Chase Turbo offers a Multiplayer Split Screen mode that rescues the nostalgia of playing with your best friends sitting on a couch all night long.
“Horizon Chase Turbo is inspired in the past without letting go of its contemporaneity. The apparent polygon and secondary colour aesthetic results in a unique atmosphere.
“In Horizon Chase Turbo you’ll pilot your car through extraordinary places, watching the sun setting, facing rain, snow, volcanic ashes and even severe sandstorms.”
