Update 01.084 - DirectX 11, Station rotation

DirectX 11 renderer has been added to the game. It is available as an option in Graphics settings and players can choose between the old DX9 and the new DX11. The main advantages of the DX11 renderer are better game performance and visual look of the models. The renderer is still in early stages of development, so some bugs and visual issues may be present.
The DX11 renderer of the game uses physically based rendering (PBR), which helps to achieve a more realistic look, especially for metallic surfaces. For modders, it means that they will have to create a new set of textures for DX11. We will be slowly replacing old placeholder models with reworked assets. Five updated blocks are released in this update (Beacon, Gyroscope, Warhead, Projector, Spotlight).

Additionally, players will now have the option to rotate a static station by switching to rotating mode (via pressing the 'B' button). The station created in the Station rotation mode will not allow blocks separated from it to be merged again.

About This Game

Space Engineers is a sandbox game about engineering, construction and maintenance of space works. Players build space ships and space stations of various sizes and utilization (civil and military), pilot ships and perform asteroid mining.

Space Engineers utilizes a realistic volumetric-based physics engine: all objects can be assembled, disassembled, damaged and destroyed. The game comes with two game modes: creative and survival.

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 aspects, but can be played as a tactical shooter as well. We expect players to avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications. Space Engineers shouldn’t be about troops; it should be about the machinery you build.

Collectors can collect small objects (ore, ingots, components, tools) into inventory. Connectors can throw items from inventory to space (in future update could be used to connect two ships/stations and transfer items)
  • Artificial mass – can be used to add gravity-affected mass to ships, useful in machine ships or cars
  • Wheels - use them with rotors and artificial mass to build vehicles
  • Automated turrets – gatling, missile and interior. Turrets are used mostly as defense mechanism rather than shooting other players. They aim on decoys (automatically by default), meteorites, missiles or all moving objects (eg. small/large ships) - targeting can be changed in the control panel

Early Access Review
Perhaps you'd like to hear about the game from the perspective of somebody besides those who have played the game for a half-hour, ragequit, then posted a negative review? If so, read on.

If you've ever wanted a game that allowed you to build your own spaceship from scratch, pilot it, take it into combat, and walk around inside of it...this is the game for you. More about this kind of awesomeness in a moment; but first let me mention some of the rough edges.

The game is still in Alpha (early development), and is an Early Access title...meaning that you're not going to have the same level of polish as something that sits shrink-wrapped on the shelf at GameStop or Wal-Mart. At the moment, the multiplayer experience is quite laggy and can be frustrating. The single-player mode does not feature any AI opponents. If you're not willing to deal with this right now....put Space Engineers on your wish list and come back in 6 months or so. No, seriously.

For me, two things keep me playing: the potential the game offers, and the dedication of the developers at Keen Software House. Every single week, including during Christmas and New Year's, they have released an update for this game. Not just bug fixes, but often new functionality. You'd be hard-pressed to find another Early Access developer with such a reliable schedule. When you look at these updates week-to-week, it may not be that impressive; but when you consider what they add over the course of a month or two, it's amazing. And the game keeps getting better.

Some negative reviewers have given SE a thumbs-down simply due to the developer's comments regarding the recent Steam paid mods debacle. The truth is, Keen Software House has not committed to paid mods at this time, but rather is adopting a "wait and see" approach. What they have done, however, is provide excellent modding support to their game -- which is more than what one can say about many other titles out there, from far larger studios.

By the same token, some negative reviewers have implied that Keen Software House isn't supporting the game now that they've started work on their newer title, Medieval Engineers. This is demonstrably false, as the level of support for Space Engineers has not changed. Additionally, the developer has repeatedly stated that they have hired a completely separate team to work on the other game.

So let's talk about what makes Space Engineers so awesome.

  • It has a fully 3D, procedurally-generated environment. Think Minecraft....in space. While there are options to generate smaller playing areas, the game is capable of supporting a playing area as large as our inner solar system. Mineable, destroyable asteroids are generated on the fly...with larger bodies (small planets) coming in the near future. This isn't a top-down, only-move-in-two-dimensions kind of game.
  • Gravity. Even though gravity generators do exist in the game, often you'll be working in a zero-G environment. Ore you mine and parts you drop may float away. More complex gravitational fields will generate interesting effects and can even be used for weaponry.
  • Physics and block deformation. Most objects in the game have inertia, and won't stop on a dime. Collisions will occur. Weapons can cause knockback and explosions. When damage occurs, the damaged blocks don't disappear: they will be torn, deformed, or even blown off.
  • Blueprints and Steam Workship integration. Create a cool ship? You can share the blueprints with your friends both in-game or through the Steam Workshop. Likewise, you can find a lot of really cool ship designs -- ranging from original creations to those inspired by Star Trek, Star Wars, Babylon 5, Firefly, Battlestar Galactica, etc -- that you can easily bring into your own game. Likewise, there are hundreds of community-created mods available that you can use with just a couple of clicks.

No, I'm not associated with the developer nor do I have any financial stake in the game other than the $25 I originally spent on it. I do think that it is one of the most promising and unique sandbox games out there. If you're still not sold on SE, I would encourage you to check out both the forums on the developer's site as well as /r/spaceengineers on Reddit. Read the comments and ask questions, so you can make an informed decision on your potential purpose. I suspect you'll like what you see.

Early Access Review
An absolutely fantastic game in the process of becoming even more fantastic. For instance, we have been promised planets to land and build on. They are in the process of upgrading from DirectX 9 to DirectX11 support (without ditching DX9 for older cards). There has been talk of AI. The multiplayer is being completely rebuilt into something far superior. If you liked your space legos like I did, this is a game for you.

Early Access Review
My favorite game. Ever. The Devs are great, working to provide weekly updates and great content. Many of the negative reviews say that they are having to split time between Medieval Engineers and Space Engineers, which is completely un-true. There are two equally capable teams for each game, giving both games the attention it deserves.

If you like using your creative side of your brain, Space Engineers is for you. The possibilities are endless in this game. First thing I would recommend is to join a server to play on. Playing with others is TONS more fun. :D

Early Access Review
Space engineers is simply a fantastic game for the gamer who is into creation in a sci-fi atmosphere. Basically, the point of the game is single/group/multiplayer (vs) survival (or sandbox) creation of ships and stations in space. Player vs. player combat is virtually nonexistent, as the point of the game is to create ships and bases to do the combat for you. The building possibilities are relatively endless, as new parts are added with each update. It is somewhat 'HD Minecraft'-esque in that all parts are geometric (though the asteroids are not). It is rather graphically demanding for the texture quality, however this is somewhat expected in a game where hundreds of objects are rendered constantly, at once. The multiplayer experience is so-so, in that private servers are a ton of fun, but public servers ultimately lead to griefing of your structures the moment you log out. There are other space games other there, like KSP, but it is hard to compare the two in a which-is-better way, as their playstyles are far too different.

tl;dr: 8.5/10 Fun sandbox creation game.

Early Access Review
Ignore every ♥♥♥♥♥ who read a status limited to 140 characters by the developer's CEO about the whole paid mod fiasco and decided to give this game a negative review. They're just crying because Marek Rosa is engaging in conversation about the issue.

Look at the screenshots, look at the community ( forums.keenswh.com ), look at the workshop, and then decide if you think it's worth your time.

The devs are incredibly responsive to the community of the forums, and there's been a tonne of discussion about the paid mod fiasco and what it would do to the game. It's highly doubtful (Read: Never going to happen) that Space Engineers will implement paid mods.

Amazing for serious survival players aswell as chill creative players. Survival can get boring sometimes, but then all you have to do is go raiding the NPC ships, and it will not be boring anymore. One of my favorite sandbox games of all time.

I love this game.

For the first 30 hours I just made crappy attempts at ships and crashed them into asteroids.

For the remainder if the time I've been playing a survival world(Galaxy? Universe?), with my brother, and its been great fun.

I can't build an Ikea wardrobe for ♥♥♥♥ but I can certainly build a fabulous fighter jet.

I've been playing a following SE for over a year and a half, and it is one of the best building games around. A lot of crap has been thrown around lately, and most of it has nothing to do with SE. So here is an actual review of the game

Pros:
-Building stuff in space!
-Weekly updates
-Constant interaction from the devs on the official forum
-Awesome modding community (some are even incorporated into the base game)
-Hilarious bugs

Cons:
-Sometimes game-breaking bugs (usually fixed within a few days of appearing)
-No real goal in game (just survive/build stuff)
-Multiplayer bugs (was added due to community request, works, but it's buggy)
-Long term bugs (asplody-pistons/rotors)

It is a work in progress that is actually progressing quite nicely. So what if the devs like the idea of the modding community getting paid for their work? It isn't mandatory for the mod publishers to charge, and most of the publishers are against forcing payment.

TL;DR: Awesome game. Updated weekly. Still has its issues. Paid mods won't affect SE.

I can only say positive things about the team that is currently developing Space Engineers. They are easily the most dedicated and reliable developers I've ever had the pleasure of watching. Over the past.. year and half? I don't know, whatever, they have grown what was little more than a tech demo into a game that is incredibly immersive.

If you like sandboxes, space, and physics, this is the game for you.
