Update 2: Although Olympic Games Tokyo 2020 – The Official Video Game is still showing as in the Free Play Days section on consoles and in the Microsoft Store, it does appear that Two Point Hospital: Jumbo Edition is a Free Play Days title instead. Apologies for any confusion!
Update: Despite appearing over on the Microsoft Store as part of Free Play Days, Olympic Games Tokyo 2020 – The Official Video Game is currently not available to download for users. When looking at the Free Play Days section on an Xbox console, an image of Space Engineers and Two Point Hospital appears, but when clicking through, Olympic Games Tokyo 2020 is showing in what we think could be Two Point Hospital's place. It looks like Microsoft has made a mistake here. We'll update you once we find out more.
Original Story: This weekend, Xbox Game Pass Ultimate and Xbox Live Gold subscribers have two games they can play for free, thanks to Free Play Days. Olympic Games Tokyo 2020 – The Official Video Game and Space Engineers are now free to play until Monday.

Space Engineers
Description: Space Engineers is an open world sandbox game defined by creativity and exploration.
It is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, wheeled vehicles, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.

Space Engineers
Space Engineers is an open world sandbox game defined by creativity and exploration.
It is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, wheeled vehicles, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.
Space Engineers features a realistic, volumetric-based physics engine: everything in the game can be assembled, disassembled, damaged and destroyed. The game can be played either in single or multiplayer modes.
Volumetric objects are structures composed from block-like modules interlocked in a grid. Volumetric objects behave like real physical objects with mass, inertia and velocity. Individual modules have real volume and storage capacity.
Space Engineers is inspired by reality and by how things work. Think about modern-day NASA technology extrapolated 60 years into the future. Space Engineers strives to follow the laws of physics and doesn't use technologies that wouldn't be feasible in the near future.
Space Engineers concentrates on construction and exploration aspects, but can be played as a survival shooter as well. We expect players will avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications to survive in space and on planets. Space Engineers shouldn’t be about troops; it should be about the machinery you build.
CORE FEATURES
Planets and moons – fully destructible & persistent, volumetric, atmosphere, gravity, climate zones

Building blocks - over 200 blocks (gravity generators, jump drive, turrets, doors, landing gears, assembler, refinery, rotors, wheels, thrusters, pistons, wind turbine and many more)
Electricity – all blocks in a grid are wired in an electrical and computer network; electricity is generated by nuclear reactors or various power sources
Gravity – produced by planets and gravity generators. Spherical gravity generator also available.
Symmetry/Mirroring – useful in creative mode when building structures that require symmetry
Weapons – automatic rifle, small and large explosive warheads, small ship gatling gun, small ship missile launcher
mod.io Workshop – share your creations with the Community (upload and download worlds, blueprints)
Localized interface
- Official localization: English, Russian, Chinese, German, French, Spanish
Cargo ships - auto-piloted vessels (miners, freighters and military) that carry ore, ingots, constructions components and other materials from sector to sector. They can be looted but beware, they often contain booby traps!
Oxygen - take off character's helmet, generate oxygen out of ice by using the oxygen generator
Hydrogen - hydrogen thrusters, hydrogen tanks and hydrogen bottles
Factions - create and join factions, determine ownership of blocks and manage the relations between them (hostile/ally).

GPS - create, send, receive and manage GPS coordinates in the game
Voxel hands - shape and form the asteroids and change their material (creative mode only)
Sounds – realistic and arcade mode
Space Engineers utilizes an in-house built VRAGE 2.0, realistic volumetric-based physics engine: all objects can be assembled, disassembled, damaged and destroyed.

Performance Notes
The performance depends on the complexity of your world and the type of your Xbox. Simple worlds run smoothly even on old Xbox, but a more complex world with rich object interactions could overload even XBox One X.
If you started Olympic Games Tokyo 2020 – The Official Video Game when it was free to play last weekend and didn't quite get it finished, you now have a second chance as it's been included once again in Free Play Days. According to estimates, it should take between eight and ten hours to unlock all of the game's achievements — something which should easily be doable in the time you have. However, the Medley (Online) Master and Quick Match (Online) Master achievements might prove a bit of a headache to some. Also available to play this weekend is Space Engineers, which, unfortunately, is currently sat with one unobtainable achievement. While Space Engineers' base achievement list is fine, The Playing it Cool achievement for the Frostbite Pack DLC has been unobtainable since it launched back in August last year. If you're not too fussed about the unobtainable, then Space Engineers will take you a whopping 150-200 hours to complete.
Olympic Games Tokyo 2020 – The Official Video Game and Space Engineers are now free to play up until Monday. Will you be checking out either of these games?
