Update 01.075 - Airtight hangar door, New turret targeting options

Airtight hangar door has been added to the game. Players will now be able to build large pressurized hangars for their ships and stations. Additionally, new options for turrets are now available that allow players to set targeting solely on stations, characters, small ships or large ships. Moreover, players can now switch the oxygen and sensor blocks ON/OFF from the toolbar, timer and sensor. Also, rockets will no longer destroy non-armor blocks in one shot and they will require less material for producing them. Lastly, we added a scrollbar for actions that can be assigned to toolbar in G screen.

Update 1.074 – Oxygen!

Oxygen has been added in Space Engineers! This means that now you can take off your character’s helmet, but only inside the medical room. When the character takes off the helmet inside an environment without oxygen, he will receive damage. In addition, you are now able to obtain ice and generate oxygen out of it by using the oxygen generator. Moreover, we’ve implemented the “drain all” option for the sorter block that will push all items trough the block and the "switch" statement for the programmable block.

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.

Early Access Review
So I picked up S.E. after it being described to me as Minecraft in space, and seeing as I liked minecraft, and space, I figured this would be a hit with me.

Yeah buddy it is.

One day I can decide to build a trading station in the middle of nowhere purely for the fun of it. And the next day, I'm building a fleet to pass by and destroy said station. I can make my own goals, my limits are really only what I can think up, and whatever the game lacks atm I can probably find a mod for.

Sure, when I started playing and atm it's still early access, but it's regularly updated with a great dev team and an impressive modding community as well. Think you've got the hang of everything available? Subscribe to some of the mod packs available through the workshop, that'll keep you busy for months all on it's own.

If you've ever played or watched anything sci-fi related and thought it'd be cool to build that. Get this. Why wouldn't you want to build a Star Destroyer or the USG Ishimura? Just sayin.

I have played this for a hair over a year now. I have logged more than 1700 hours in game.
Worth the 20.00 I paid!
If you love/loved Legos (the toy not games lol) then you will love this game.
There are other aspects but I want to keep this short.

If you like building, if you like space you can't go wrong buying this!

Even tho I prefer Medieval engineers because of the setting, space engineers is excellent because it's the same gameplay and core mechanics, so i recommend.

It's like you're a space game fan get space engineers and if you're a medieval fan get medieval engineers, or if you want the complete experience get both.

Early Access Review
Amazing game. Here are pros and cons:
Pros:
1. Great mechanics
2. Physics are amazing
3. Truly envolves engineering in almost everything you do, making the title fit excelent with the game.
4. Update every thursday with new features and bug fixes.
5. Adding mods is easy, and are on the workshop.
6. Worlds, blueprints, scripts, and mods on the workshop.
7. Decent graphics.
8. Easy multiplayer setup.
9. Almost an endless amount of designs you can make. Like for real, if you can think it through, you can build it.

Cons:
1. Does require a good processor, otherwise you'll lag with REALLY REALLY large ships, otherwise you'll be fine.
2. Survival only has ships that spawn that you can raid, not actual npc astronauts.
3. The occasional bugs and glitches, but there are barely any.

More pros than cons to a 3/1 ratio. One of the best sandbox games out there. Better, a little cheaper, a lot more freedom and creativity than minecraft BY FAR. 20/10.

Early Access Review
This is a game that was made for people just like me. It looks like Minecraft in space, but it's more than that. It gives you the tools to solve problems, and the fulfillment you get after coming up with your own solution is a feeling sorely lacking in other sandbox games.

The survival mode in this game gives you a lot of content. I've been playing it for more than forty hours and I haven't even managed to set up a decent mining operation. You can also hijack other ships and take them apart to build new ones. You can stop them in a craft that you made or even just in your spacesuit (if you know what you're doing) - they're all coasting on autopilot and with automated weaponry that makes approaches tricky. The fun is in the trial and error, and figuring out the best way to do a seemingly simple task.

Is your mining drill inefficient? Build a mining ship. Is the hand welder too slow for you? Make a welder-equipped craft. Do you need to strip and salvage a giant capital ship you just captured? Maybe a corvette with six grinders is what you need. Creativity and resourcefulness is rewarded.

The creative mode is also great for shooting things with other people and making fantastic designs of ships on your own. There are ways to save schematics or blueprints of your designed ships so that you can build and use them in survival mode. The devs are also great in that they update really often, and for an alpha version (I rarely buy games on Early Access) my money has already been well spent. BUY IT AND PLAY WITH ME AND YOUR OTHER FRIENDS!

Early Access Review
One of the better "early access" games, in that it actual feels like its moving forward and will be finished. Most will say SE is just "Minecraft in space" but not really. Ship building and base building only half the game. Mining/transporting resources need to survive in space make this game fun. Now a lot of the new factions/protection still in progress but for I like were the game is going. Lastly Steam support for mods is amazing and people have come up with a lot cool stuff in short time its been available. If you like building sims (like Minecraft) or space give this game a try.

What I'd like to see in the future:
-More exploration (expanding space or warping to other pockets of asteroids)
-Need for O2 on space station/ship
-More tools/machines
-More ores/resources
-More variation of asteroids both in size and amount
-Planets

As of now (200+ hours) loving the game and looking forward to the future of it.
***9/10***

Early Access Review
I can easily say that this game is amazing. You combine the wonder of space with (somewhat) futuristic technology with man and you get this. Floating around in a 3d environment with no gravity is mesmerizing, as well as getting caught in the orbit of your own gravity field. Everything is destructible, and for a sandbox game as detailed as it is..it's surprisingly non linear feeling and particles even fly off things that are destroyed. Actual physical non blocky particles that have their own physics. Just amazing. You start off in a tiny spaceship. Your goal is to find an astroid, mine. Do whatever. Build a base, establish a gravity field in it. Get a constant flow of fuel for your gravity (Uranium I believe) Hijack rouge or abandoned ships that are faraway and often difficult to reach and get control of, as they're turned off and are drifting through space. While this is difficult, it can really pay off in terms of materials, fuel, and having a huge spaceship to either use or add onto and make it into your own kind of spaceship. Their is an uncountable variety of things you can do/build in this game, as well as very fun space combat. Space combat is very expensive and can often destroy what took you nearly an hour to build. Ramming ships into others is often looked down upon (atleast in friendly servers) but it is very fun to send your own ship flying through another and making a big hole. Everything feels free and non linear. I raite this game 9.6 out of 10. You can do amazing things especially if you've got a few hours or more to sink into this game with a friend or two.

Great game, its like minecraft, but in a totally different environment, real life physics and Action components makes you able to build just about any real life machinery.

I still remember clearly how it was when i first had built my own mining ship, and how i progressed and learned making better and better versions.
And its all about pushing the limit, of how advanced, compact you can make them.

You can build your designs in singleplayer creative mode.
And the best part SHARE VIA STEAM WORKSHOP, anyone can use your blueprint.. or you can find and download blueprints.
Really easy proccess.
Then create hologram projectors, to project the blueprint you've made, then drive a welding ship around it, and voila.

Go explore asteriods, and find minerals for building.
Create bases with automatic doors, lever controlled blastdoors, design solar plants to power your base, to save fuel.
Hijack patroling ships, or attack players.
Sky is the... no wait, Space is the limit!

S.E. is a lovely space sim with remarkably good physics, gravity, and block deformation. Great with friends. A rich & thriving mod community have made some brilliant contributions that really improve vanilla gameplay. The fact that Keen releases weekly content updates every Thursday shows commitment to a delightful early access game.

Space engineers is an amazing game. With constant updates, great modding community and active servers all around it doesn't just dump you in the world and let you fend for youself. Playing the game does, however, plant you in the middle of nowhere and you have to figure stuff out. That is great. Multiplayer suvival is fun, with multiple ways of making your ways around the universe. Creative, of which I've only played SP, is awesome. The amount of things you can build and design, even without mods, is amazing. It does fit into the same catergory as Rust, that being the "I'm an ♥♥♥♥♥♥♥ with a bigger gun than you" but it takes longer and is harder to achieve getting some serious fire power and every fight leaves you with something to do, like repairing damaged hulls or reloading rocket launchers. 9/10
