Update 01.079 - Oxygen Farm, Disabling encounters option

The Oxygen Farm block has been added to the game. It works similarly to the solar panel, but it produces oxygen instead of electricity and doesn't require ice to work. We also added the option to disable encounters in the world. Additionally, the "Save As" option can be now accessed while the player is in the game (on the Main Menu by pressing Esc).

Full list of new features and fixes:

EDIT 04/24/2015:
Update 01.079.008
- fixed crash when equipping tool with custom character
- added interface for oxygen farm

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
I have Spent a very good portion of my life game, and I dont see myself stopping anytime soon.

The game sets you in a deep space environment, with the ability to set and infinite world, full of randomly generated objects, and asteroids. Your job is to survive. You have your hand tools, and whatever is in your spawnship. Mine to get ore, refine the ore in a refinery to receive ingots, then assemble the ingots with an assembler to get materials, use the materails to build stuff with your welder. The stuff you build is up to you. You can build a station, a mining ship, a utillity ship, or a Military ship. How big can you build the ships? As big and as intricate as your computer will handle.

It just doesn't get boring, because the devs release an update every Thursday. With the addition that they acctually listen to the community. So when an update comes along, its exactally what you wanted or better (about 70% of the time). The steam workshop plugin fills in the other 30% by having custom mods and blocks. Mods can be easily placed in your game with and in-game GUI made just for the steam workshop, so no file surfing. All-in-all it is one of my best buys on steam, Im sure it will be one of yours as well.

Buy the game.

Early Access Review

Space Engineers is a game about building, and surviving. From afar you could say this game is similar to the popular indie title, Minecraft. However upon a closer, more detailed inspection, the titles only share two similarities. They are, of course, custom construction and an open world environment in which to build or explore.
Space Engineers is everything a child born in the early 80's and late 90's could want, jam packed into an ever evolving and ever changing environment. If you've ever seen one of the more popular Sci-Fi space series/movies, you'll understand right away. Most sandbox construction games, like Minecraft, have simplistic dynamics and challenges. However, in a game like Space Engineers, one could easily find themselves in a very serious predicament. Rather than having to worry about food and shelter, the player instead must worry about energy reserves, materials and resources, and (as of the latest update: 1.076) oxygen reserves.
Now, on the outside these are very simple things. However, anything can happen. As with Murphy's Law, which finds itself very deeply rooted in this game, if it can happen, it will. Case in point, you could be inside your sealed up station building a ship in your hanger. Your helmet is off, you're breathing the oxygen in your hangar, happily building away on your newest ship. Your buddy was just out mining and has just returned home. He doesn't know you are in the hangar (which is pressurized, hence why your helmet is off), he opens the door to bring his ship in to dock. This depressurizes the entire hangar and now you are inside, suffocating to death because your friend has just vented all the precious oxygen into space by accident. This emphasizes safety precautions and other means by which the player can ensure that accidents, don't happen.. well, at least not as much.
The only enemies you have are yourself, and other players. However, there is a simple form of hostile in the game. These are NPC ships which, for the most part, wont bother you at all. Unless you try to board them and steal their resources. Then the only thing to stop you are the exterior turrets and well... the ship itself if you happen to be flying too fast towards it. Hostile AI Engineers have yet to be introduced into the game, but many players (myself included) are looking forward to some form of AI, be it hostile or friendly.
The game has two game modes, Creative Mode, and Survival Mode. Creative mode is good for people who prefer to build things rather than worry about materials and their survival. Creative mode, is just that, infinite resources and all the reason in the world to build whatever you want. However it goes beyond that in Space Engineers. Your options are not just limited to building ships and stations. You can build asteroids as well. Space Engineers uses a Voxel based generation system for their asteroids and the destruction physics, which we will get to later on. The Voxel system has made it possible for players to edit asteroids to the point of custom space rocks that look like Vin Diesel. But it doesn't just have to end there, this system allows players unlimited creativity, even to the point of changing the very material that the asteroid is made of. You can choose between every resource that is available in the game! However, at current, Voxel editing is only available in Creative Mode.
Now on to one of the most prominent features in the game, destruction. Everything in the game is capable of being destroyed, warped, borked, bent, and misshapen. If you build a ship and fly it into a rock, chances are you will destroy your ship, if not, your going to be in for a world of hurt when your mechanic sends you the repair bill. This destruction system opens up entire worlds of possibilities for the way the game is played.
Remember earlier when I mentioned exterior turrets? Well, there you have it, weapons. Ranging from a hand held assault rifle to ship mounted rocket launchers. You can have manual systems like gatling guns and rocket pods, or automatic systems, like gatling turrets and rocket turrets. Each have their advantages and disadvantages. Each can be utilized in its own way and the customization options for these weapons allow for nearly infinite possibilities when it comes to combat.
This game has it all, and with Keen Software House (KSH) putting out an update every Thursday, there's no end to what it contains or what will change. If you like construction games, open world exploration, strategic challenging survival scenarios, or just like space. This is the game for you. Currently it is only available on PC in early access from Steam, or directly from KSH's website. However, console gamers need not fret. Keen is keen to get it released on console sometime in the not so near future.

Early Access Review
Being an early access game, I went into SE right around the drop of multiplayer not expecting much. At first I honestly didn't care for this game. I even remember thinking "this game is a joke" during my first couple hours of play. Could you blame me? The guns did not work, block choice was very limited, and the doors (at the time) only opened half way. After a few hours of play though, I was getting the bug.

Space Engineers has a fantastic community which is in my opinion the number one reason to play it. The modding community is heavily supported by the developers and definitely adds another dimension to the game. If you are looking for new turrets, coded scripts for the programmable blocks, or even just ideas for what to build next, the modders are there to help.

Keen Software House has done an amazing job with this game so far and they have delivered on everything they have promised the players, from survival, multiplayer, dedicated severs, exploration, factions, to just keeping up with an update a week, they have not let the players down. Always able to surprise us with new blocks and game options while simultaneously keeping up with the bug fixing an Alpha game needs.

If you are a fan of the ever addicting sandbox genre or science fiction, pick up a copy of Space Engineers and give it a spin. I've put over 1000 hours of my life into this game and once you build your first ship you'll understand why.

10/10 I can make my sci-fi fantasies and adventures true with this.

But seriously, don't let the early access tag scare you away. This game is probably the best of it's kind. It is a sandbox situated in space. You, the player, can build pretty much anything you want. If you can imagine it, it can be built. Whether it is survival or creative that you're playing, you are guaranteed to have a good time. Don't get frustrated if the game seems complicated at first. There are many community guides to help you along the way. Speaking of community content, Space Engineers has a massive modding community. If there's something you need in your spaceship/station, there's a mod for it.

I have never tried MP. SP has kept me busy enough, with me trying to create and re-create ships. With the so called "Explorer mode", you can have an interesting adventure, if you don't feel creative.

If you like space, building, sandboxes, and games that require some intelligent thinking, then this is the game for you.

I am bloody serious. Buy it. It is totally worth the money. With quality like this, you'd expect the price to be about 40-50€.

Keen Software House should feel very proud of themselves.

This game is simply amazing. You mine materials and build stuff. Stations, big ships, and little ships, with a wide offering of combat and non-combat capabilities. Unlike many other games, Space Engineers does not force you into combat if you don't want it to.

So if you love building stuff and love sci-fi, Space Engineers is probably for you.

Space Engineers is a game where you play in space. Pretty obvious by the title...Its a sandbox game meaning you can do what you like its called Space Engineers because it provides you with lots of matireals to build with or do what every you want with you can do lots of fun things like; Drive a space ship or Build a ship or a space station etc. etc. So i think you should give Space Engineers a go my review would be 6/10 not the best but also not the worst.

I love this game. Plain and simple. It isnt overly complex, and is relatively easy to master. This game is one of my favorite (if not my favorite game of all time). I get that there are bugs, but its early access. Keen Software House is trying there hardest to try to update the game as much as they can. They add new stuff and fix older bugs almost weekly. It has come a long way since its origins from alpha, and is so much fun. Thanks Keen!

Space? yes.
Building? yes.
Spaceships? Absolutly.

this game is so fun, its taken up a majority of my time. With it being an early access game, it def. has its issues here and there, and i hope they fix the issues that happen in multiplayer, but overall its a wonderful game. every thursday i'm excited to see what new things they'll add to the game, and every day i check the workshop for new and exciting mods, because that just makes the game 10x better.

I also love the fact that you need to find materials, break them down, and craft them into parts that you need to build the blocks. It still runs on Direct x9(at the time of this writing) and i'm stoked for the Direct x11 update, or x12 if its out by then. i've only had this game for about a month, and i've already spent 261.8 (at the time of this writing) on it. (I know i dont have a life) but its super fun! even with all the multiplayer quirks, like occasionally low sim speed(which has to be fixed by server admin by cleaning up junk) its still a ton of fun to build with others.

This isnt just a Minecraft in Space. Its a whole other thing. Its complexity is simple enough to learn, and designing new ships is a blast!
I'm stoked for full release, even if it never comes!
As long as its constantly updated with new features, and better system handling, I'll play this game for a long time.

Space engineers is a very solidly made game. Over time many more improvements are sure to come out. I remember when this game frist was released and how bare bones it was. The dev's make sure to be on tempo with their updates almost every thursday, to ensure players have something new to enjoy and tweak within the game. From the release of weapons in game, all the way to atmosphere. Space engineers has come a long way, and has much more ahead of it.

I can't begin to say how much I've enjoyed this game. I look forward to just sitting down and putting together some ship designs and having fun. There are some people that get really serious with this game (and that's cool too) and they create some really awesome things! I am not a hardcore critic, but I would recommend this game to anyone that loves a good sandbox/space/creation game.

the best game ever if you get bored well you won't but if you do make a ship it will need lots of things but if you make a fighter you can blow cargo ships up and even blow your friends up but if you don't have friends then it's still a great game to play by your self...I highly recommend this game

One of the better Early Access games on the Steam library. Constant updates, strong developer support, and it's fully playable right now. Funny thing about being an Early Access game is that there's very little bugs in it. You can build huge space docks, large cargo ships, tiny fighter ships, or combine all of those to make a large army. Multiplayer is very fun too. Highly recommended for people who love space and sandbox games wanting to be able to create their own space ships. There's a steep learning curve though, but it's worth learning to be able to create whatever you desire.
