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.

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:
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.

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
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

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

If you can think it, you can build it. If you can build it, you can rebuild it to be better. The only limit to this game is your imagination (and your PC). Right now it is in Alpha and there are a few kinks that the devs are still working on. Some are major, to be fair. However, they are adament about fixing problems and they clearly have a game plan that they are working with. I'll be honest, I've been frustrated at times with the lack of optimisation at the current build, which does affect playability, as it very clearly says that it will in the Early Access banner above. This doesn't mean that it's a game to be passed up though, to say the very least. The game is in development, and the devs show no signs of slowing down or halting progress on their game.

The developer involvement in the community is top notch, absolutely excellent. As many other reviewers have stated, Keen Software House is definitely setting the bar for how Early Access games on Steam should be done. Just the other day I posted a bug on their forums, and one of the devs by the name of "Phand" got back to me in 10 minutes. He had me send him my world that I experienced the bug in and forwarded the situation along the appropriate channels. Even if it isn't fixed in this next update, I'm not going to be here complaining because I know it will be as soon as they figure it out.

But, the devs not only communicate well with the community, they also expand on ideas and are working to make the game better than anyone could have imagined it being six months ago when I first got the game. It has absolutely evolved past what it was at that point and is well worth the asking price. I have bought several copies of this game for friends and have met many excellent builders in the game.

The UI is a little invasive at times, especially when building something from the inside. But, there are mods for that and I have little doubt that it's not something that the developer has on the to-do list. Speaking of which, if you want something that isn't in the game, you can almost always find a mod for it. The modding community is very talented and there are many coding experts that have developed tools for the game that are available to you for free.

And, if you yourself are a coder, check out the programmable block! There is literally a block in the game that you can use C# to program scripts into to execute actions for you on your ship/ station. Not your thing? Or don't know how? Not to worry! You can use scripts from the workshop to make your creation come to life before your very eyes!

While the game is no doubt a lot to take in and can be daunting at first glance, the workshop also has examples of ships you can build, and YouTube is littered with in-depth tutorials to get you up to speed. Not to mention the countless guides from the community that explain everything to you in text, if you prefer that to a video.

All in all, it's a dream come true for someone like myself who spent a lot of time as a kid building Lego space ships. I can't wait for the game to progress further, and it's a very safe bet that it will be the best game of its kind.

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'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.

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

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.

If your looking for a review on this game you've come to the wrong place, but if your looking for an outstanding pie recipe you've come to the right place.

1. 6 tablespoons unsalted butter
2. 1/2 cup white sugar
3. 1/2 cup brown sugar
4. 1/4 cup water
5. 1/4 teaspoon cinnamon
6. 1 pinch salt
7. 5 apples - peeled, cored and sliced
8. 1 pastry for double-crust pie

1. Preheat oven to 425 degrees F (220 degrees C).
2. Combine butter, white sugar, brown sugar, water, cinnamon, and salt in a saucepan over medium heat. Bring to a boil, remove from heat and set aside.
3. Roll out half the pastry to fit a 9-inch pie plate. Place bottom crust in pie plate; pour in apple slices.
4. Roll out top crust into a 10-inch circle. Cut into 8 (1-inch) wide strips with a sharp paring knife or pastry wheel. Weave the pastry strips, one at a time, into a lattice pattern. Fold the ends of the lattice strips under the edge of the bottom crust and crimp to seal.
5. Pour butter-sugar mixture over top of pie, coating the lattice, and allowing any remaining sauce to drizzle through the crust.
6. Bake in the preheated oven for 15 minutes. Reduce heat to 350 degrees F (175 degrees C), and bake until the crust is golden brown, the caramel on the top crust is set, and the apple filling is bubbling, 35 to 40 more minutes. Allow to cool completely before slicing.

Really fun spacebuilding game. Most definitely beats Garry's mod's spacebuild maps and gamemodes.

For the moment, in the survival gamemode there isn't much to survive from. Suit energy and random meteor showers hardly provide a challenge. With enormous drill-ships and refinery-assembler factories you can build pretty much anything.

Building however, is quite fun. With mods there's a great deal of things you can build. Only your imagination is a limit.

For a an alpha, this game is quite good already. Some techinal issues and bugs are bothersome, but I think they will be solved over time (lack of multithreading in dedicated servers limits player count, lack of optimization, pistons and landing gears are buggy/laggy).

5/5 gonna keep playing
