Update 01.120 - Highlights, bug fixes

Update 01.120 is out featuring highlights on floating objects, faster browsing for blueprints and bug fixes.
We also resolved the issue with crashes caused by using custom skins. But be careful as your character may die due to lack of oxygen until this custom skin has been fixed by its creator. A guide how to fix custom skins can be found here: http://forums.keenswh.com/threads/character-skins-crashing-after-01-118.7378645/

Update 01.119 - Bug fixes

This week we are introducing a new batch of bug fixes.
First off, on the optimization side we made sure your GPU wont overheat on loading screens and main menu by limiting the frame rate output. During the actual gameplay the limiter is off.
We also turned down the aggressive nature of Cyberhounds. From now on the dogs will attack but they wont explode anymore in kamikaze fashion. Your creations are safe when you are not around to defend them.

About This Game

Space Engineers is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.

Space Engineers features a realistic, volumetric-based physics engine: everything in the game can be assembled, disassembled, damaged and destroyed. The game can be played either in single or multiplayer modes.

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

Early Access

  • Planets and moons – inspired by real celestial objects (Earth, Mars, Alien, Moon, Europa, Titan), fully destructible & persistent, volumetric, atmosphere, gravity, climate zones
  • Game modes
    - Creative – unlimited resources, instant building, no death
    - Survival – realistic management of resources and inventory capacity; manual building; death and respawn
  • Single-player – you are the sole space engineer
  • Multiplayer - alpha version (not a final version)
    - Creative and survival mode with your friends

    - Crashed Red Ship – your mother ship just crashed...
    - Two Platforms – competitive two-team multi-player world
    - Asteroids – start in a rescue ship with very limited resources
    - Empty World – no asteroids, no ships; suitable for creative mode
  • Enemy NPCs
    - sabiroids (spiders): can be found on alien planets and on Titan moons. They can destroy metal blocks and attack players. Their favorite hunting strategy is hiding in the ground and un-burrow to surprise their prey. When players kill a spider, new spiders won’t appear in the area for some time. They also store some components inside their bodies from objects and blocks that they consumed.
    - pirate bases: can be found either in space or occupying planetary surface. They have bounty hidden inside their containers that players can loot if they get over the drone attacks.
    - enemy drones: they spawn automatically from pirate bases and attack the players when they venture into pirate territory
  • Ships (small and large ships – build them, pilot them and crush them
  • Space stations
  • First-person & Third-person
  • Planetary bases, outposts, cities!
  • Dedicated servers - allow players to connect to a third party host, rather than using a player-host, in a peer-to-peer set-up. The result is a faster connection and a more fluent multiplayer performance with less lag

  • Environmental hazards – protect your character and your creations from meteor storms (Safe, Normal, Cataclysm, Armageddon)
  • Conveyor, Collector, Connector (IMPORTANT: this is a first work-in-progress version and a realistic version will be added later) - Conveyors move items from inventory to inventory. 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
I won't deny that I had a LOT of fun with this game, and my play time will speak on my behalf on that. But, as other early access titles, there's always a shadow looming over any potentially great title: the direction its developer will take, and how they will react to an unexpected success. I loved this game back when it was... simpler. Not in its mechanics, mind you, but in its SCOPE. It was a game in which you had to hone your space engineering skills (hence the name) to make better designs, and when you managed to build a well-designed, perfectly working ship... it was glorious. I remember how proud I was of the first semi-automated mining ship I built, the smile on my face brought me back 20 years, when I was a kid playing lego and building something I liked.

Then Keen Software House was hit by a wave of... success. They tried their best with their weekly update, and for some time I thought they were going in the right direction, with them adding programmable blocks and more engineering solutions to the already rich plate. Then they started trying to please everyone. Adding things most players didn't even want, failing to fix GAME BREAKING bugs, ignoring the pathetic state the multiplayer is in (completely unplayable as of now, has been like this for months).

Then the dreaded PLANETS. I won't lie, I was looking forward to them. But the engine showed the game itself wasn't ready for them, and they even changed the damn system requirements after adding that feature. Fact is, even with a mid to high-end gaming pc you won't be able to reach playable frame rates. I'm using a good machine myself, and my fps (10 to 20) on planet surfaces makes the game completely unplayable. And the bugs and unneeded features just keep coming.

We have exploding CYBERDOGS now, yey, and we can mod our medical room to suit our playing stile, imagine what kind of funny stuff we could do in multiplayer - oh wait... the multiplayer is currently broken. Keen is losing sight of their own creation, trying to subtly invite us to polish the game for them via MODS... their vision of this game's future is clouded by their own inadequacy.

I would NOT recommend this game to anyone right now, and I fear this might not change in the future, since the company behind it is quickly losing any credibility as a serious developer. If you're really interested in this title... well, my suggestion would be to wait. Wait and see if they can (and want to) come up with solutions to this game's long standing bugs (mining not working properly, terrible sim speed, unacceptable optimization, unplayable multiplayer) and make the right steps in order to keep the title alive. If so, I'd gladly change my review at a later date. But right now... avoid this game. It will make you think "this could have been GREAT, when and how did it go so wrong?".

Early Access Review
Removal of the immature comments has commenced. Lets keep this linear and within the bounds of reason. The personal attacks are just further adding to the demise of this game by demonstrating the childish attitudes of the current players.

http://www.eurogamer.net/articles/2013-01-07-miner-wars-2081-review
--------------------------------------------------------------------------------------------------------------------------------------------
Having played 1634 hours of Space-Engineers and hosting my own dedicated servers as well as managing my own communities for this game, I have seen the ups and downs of the progress. Early on, there was great progress, along with many new features that needed refining.

In very early 2014 I downloaded a cracked version of SE to test it out. 400 hours later I bought the game to help support and add my constructive criticisms to improve the game. Rotors, Pistons, and so much more was added!

Through many of the requests by players, we got many additions and other grand features, like warp drive, batteries, sensors, and much more.

NETCODE --- Players asked for better multiplayer netcoding, we got BLOCK COLOURS... This adding of "Flash and flare" as I call it, has done nothing but satiate the players who can't see past their own noses. This "flash and flare" has been a constant method of Keen to satiate EVERY request for multiplayer netcoding along with "Soon".

Well.. We are now nearly 2 years down the line, the game is BEYOND playable in terms of multiplayer. Simulation speeds will drop to .3 - .2 with few physics operations.

PLANETS --- No doubt a big deal. They are very impressive! Well, until you realize that you CAN NOT play on them. Search youtube for "Planetary Holes". Since then, we got exploding Cyborg Dogs... Really? More flash and flare to distract the simple-minded players from the ABYSMAL quality of multiplayer.

1 year ago I had a relatively stable world with 2 large 800 meter asteroids that I generated for my dedicated server and the community that played. The forums run by Keen were flooded with players and groups and communities with lavish ideas and doing everything they could to encourage improvements for this game.

Since then, Keen has done nothing but ALIENATE the valuable playerbase they first had. Read the replies for each weekly update, dating as far back as possible. The vast majority of the players have left, along with countless multiplayer communities. The comments have degenerated into useless "Thanks!" replies along with the "Negative Constructive Criticism" from the few valuable players who still cling to the hope that Keen will eventually fix this game.

The final interaction I will have with Keen and their products after this review is posted, is to wipe it from my personal computer as well as my dedicated server once and for all.

For a game with such grand potential, Keen has squandered it, and lost their most valuable resource - THE LOYAL PLAYERS WHO STUCK THROUGH THE FIRST YEAR OF MAJOR ISSUES. Now you are held up by fanboys parading "THANKS!" on each weekly update instead of the QUALITY that you first demonstrated. Shame on you Keen, however, shame on me for actually trusting your company and it's HISTORY of incomplete products. You have tarnished the purpose of "Early Access" games.

Early Access Review
Very good game in single player. Ive forgotten myself in the game multiple times. Creating inventions, blueprinting them and later taking them elsewhere. 3d printing ships etc. In multiplayer its another story, lots of bugs happen all the time and its been like this since the start when I bought this over 2 years ago now. Ive learned to cope with most of them.

Needs quite a good PC to run aswell. When Planets released i needed 16GB ram. Definately worth a try.

Early Access Review
All the negative reviews of the game, saying that the game is unfinished, with poor graphics and optimization...they're not wrong. But they aren't right, either.

The game is in an alpha state, and there WILL be bugs, specially in multiplayer (but that's going to be fixed in about 3 months when new netcode is implemented).

Right now the game is almost feature complete. There is way more things to explore than in other games. You could spend a thousand hours on the game yet you wouldn't explore it fully.

What annoys the people and make them post negative reviews are the details. It's true that the game has undergone some reckless patches, without any clear goal (remember they patch the game once a week. That puts big pressure on the devs, needing to release features to keep the community happy), but the new roadmap for 2016 states that things will start to be tidier.

New models, new textures, new UI. The game is not going to stay like this forever; it will eventually become and look like a finished game. So although the models aren't that pretty, the features are there, aren't they?
Even though cargo containers might be ugly modeled, they are functional, and that's what counts.

About the "reckless last patches". If you bothered to read, you'd know that the new game netcode is being developed RIGHT NOW, so don't expect big patches unless the netcode is released.

Let me tell you some of the things you have right now at space engineers:
  • Pistons: Yeah, they are buggy right now IN MULTIPLAYER, but that'll get fixed. In single player they are functional.

  • Rotors: Hanger doors, Robotic arms, hidden turrets, moving platforms...

  • Conveyors: Item sorting, automated power / item transfer between ships...Combine with rotors for epic.

  • Planets: Fully moddable planets which add several engineering challenges, such as getting out of the atmosphere of a planet (yes, there is gravity and it's not that easy to get out of the planet, specially in survival), or surviving the long trips between planets.

  • Remote control and Drones: You can send your ship out of the planet without even being aboard. Obviously, this is not easy to do, and requires engineering (and maybe, programming skills if you want more functionality)

  • Programmable Blocks: There is an extensive API out of which you can make automated ship station, item sorters, radars, status reports, cargo managers... Or just display the time in an LCD.

  • Huge modding community: The developers are also focusing on adding modding support to many areas of the game, and right now there is a bunch of mods that ADD REAL FUNCTIONALITY to the game, plus cosmetic ones that look absolutely amazing.

  • Awesome ship designs in the Workshop: You can get an idea of what kind of ships you can make taking a look at some designs made by other people. You can recreate ships from films and series, like star wars, or from games like FTL. The game offer great building mechanics that make it suitable for a wide range of styles.

So yeah, the game is not BUG FREE, nor FEATURE COMPLETE, but right now it can give you LOTS OF FUN for many hours, and many engineering possibilities with all the mechanisms / machines included currently in the game.

The only serious con I'd see right now is optimization. Seriously, if you want to play on planets with large ships, be sure to get a high-tier gaming rig. I have a 970 which seems enough for the game, and an i5 (this game is CPU intensive!!)
The game will eventually get more and more optimized for less powerful computers whatsoever.

TLDR: Despite all the bugs and placeholder models in the game, it offers many features which are already in the game and WILL give you a lot of fun, specially if you play with friends -expect bugs if you play multiplayer -.
Don't get scared because of negative reviews. The game right now is just developing new netcode and thus the weekly patches are not AWESOME and they introduce some bugs to the game.

Early Access Review
The game was decent before the planet update. After that the game has gone downhill. Pistons and rotors just exploding and ruining hours of gameplay work this is a problem that has been around for 2 years.... The game doesnt even run properly on recomended specs. The community is full of redditors with self entitled opinions that just cant accept the games faults. Cant enjoy multiplayer because their netcode is bad. Cant enjoy singleplayer because of the bad game stutters or constant crashes while flying a ship out of the planets atmosphere. I bought multiple copies to share with friends and we cant even enjoy the mp aspect of the game. Dont waste your money until they fix these bugs and update the netcode if you are looking for the mp experience......
