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.

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

It is fairly fun game, BUT developer just tweeted about a possibility of bringing paid mods to the game. (unto an early access game that is)
Absolutely terrible. The review will stay negative until it is officially overturned. Also, boycotting Medieval Engineers too. And everything by Keen games for that matter

Early Access Review
Space Engineers is a great game on its own merit. However, Space Engineers has announced they will offer paid mods. This is an unacceptable practice and I'd advise anyone who is interested in this game not to purchase it to boycott this practice.

Besides fragmenting the modding community with passionate modders and those looking to make a quick buck, this can destroy one of the longest standing pillars of PC gaming. I'm going to assume that anyone reading this review has heard of, and most likely played Counter Strike, Dota, and Team Fortress. All of these started as free community mods made by passionate modders and maintained by a passionate community, many of who downloaded the mod to see what it was all about, none of which would have happened if these mods were behind a paywall. This can also encourage publishers to push games early with the idea that the modders can patch or add missing features to an incomplete game. With Skyrim as our only example so far, many free mods are being stolen and put up on the Steam Workshop for purchase and the creators of those mods not being able to take them down.

Does anyone want to go from playing community made mods the size of DLCS to paying $0.49 for a sword reskin? No, no one at all. While people might respond to me saying that modders should get paid for their work, I agree in some situations and this is not the way to do it. Besides putting their wall behind a paywall and making it inaccessable for many, the modders only get 25% of the revenue while the game developer gets 45% and Valve makes 30%. So if you think, hey this new questline mod is worth $5, I'll buy it to support the modder you're only giving him $1.25 while the developer gets $2.25, and Valve makes $1.50. This should disgust everyone that Valve and the publishers are trying to suck nickels and dimes from every nook and cranny of gaming with the excuse that the players are entitled and need to support the modders. You know what supports the modders? Donation buttons. If you really enjoy a mod, or a modders work than you can throw $5 his way, he earned it and Valve doesn't take a single penny from it.

Dont let Valve ruin PC gaming, stop buying games from Valve, don't purchase these mods, join boycott groups, spread the word, and most importantly send Valve and Gabe an e-mail to state your opinion and dissatisfaction with their attempt to nickle and dime us at everyone corner and inform them you will not be buying anymore games from their marketplace until paid mods are removed from the Steam Workshop.

Considered and announced paid mods.

Hasn't finished Space Engineers, but moved onto Medieval Engineers development.

Pulled the same "No finish, move on" stunt with a game they "made" before Space Engineers. Which received no support after their move.

Nope your way out of here people.

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.

i have only one problem with this game... its damanding as ♥♥♥♥, probably because it renders EVERYTHING all the time... expecially things that are soo far away... i think they should add render distance... and a fps feature in the settings... and since you wont be able to see ships far away maybe add an item like say a telescope? or binoculars? or somthing above those lines? also its dark in space... in reality.. you wouldnt be able to see.. anything! so maybe have it start out at a base and have it lite up! and add a light feature! idk just spilling my brain why i dont like this game all that much... hope the developer sees this review and make a bit of changes... in the render distance and make it look dark and add light feature! also planets would be cool heh... also maybe a sun if you get to close you die! that could replace darkeness.. maybe sanity? so if you stay in the dark to long you kinda lose it? because i know if i was in space id lose it... without light anyway and just my flashlight or helmet light thing.. other than this complaint i do like the game and its features... just dont like the render distance thing REALLY" shouldnt be this damanding.. i think

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.
