Update 01.158 DEV - Improvements and Bugfixes

Hello Engineers! This week’s update brings a fresh batch of bug fixes and improvements. The visual scripting tool should be working for everyone as we fixed some issues and crashes related to it so now you can get to work on your very own campaigns and scenarios! We also increased the number of characters allowed for LCDs to just over 100,000. Bugs fixed this week include a phantom power drain when using a merge block, the view distance setting not updating and the rifle continuing to fire after going to the ESC menu. Lastly, many crashes were resolved, including ones related to the use of local mods.

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

  • 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

Early Access Review
Posted: September 23
As much as I love this idea of a game its time on early access has run out. 3 damn years on early access with no end in sight but that hasnt stopped the Devs from branching off onto another unfinished project (medieval engineers) or from deciding to try the game on console. Until then we get a broken game with a beautiful concept.

Plus the controls are an absolute pain in the ♥♥♥. All I want is a simplified menu layout not a damn headache everytime I need to open one of the multiple menus or figure out what random key does something.

Early Access Review
Posted: September 29
Space Engineers is one of the few games I've purchased myself, and sets my standards very high when it comes to Indie Developers. I've rarely seen a game in Early Access do it's best to reach it's potential, to set a goal and make great progress towards it.

With every massive leap forward however, Keen Software stumbles back a little bit. While everyone else sees these as game breaking issues that will stop them from ever enjoying the game (and with good reason), I see a developing team that is doing their best to improve.

I see it as a work of passion that Space Engineers is getting an update every week, and a stable build every month. I've seen so many games abandoned with an issue strikes, but the developers for this game continue to fix small things, and when they find a way around, the bigger stuff is fixed as well.

I won't lie to you, the silence between the devs and the community is worrying sometimes. Big issues that go unresolved for periods of time can leave you not wanting to play until they're fixed. Large updates that bring several problems can be disheartening. But if Keen had no intention to finish this game, they wouldn't continue to update it this frequiently.

So, I'm putting a little silent faith in this game, in it's devs, and in it's community, that we will all be Interplanetary Space Engineers. Instead of calling the game dead, and a mess, notice whatever improvements are coming and do your best to show support.

It's coming along, and I don't regret a single cent.

Quick little review I hope will spark some optimization and bug fixes.

Keen Software House. With all of my heart, I want to thumb this up right now.

Ive been following SE for almost 2 or 3 years now. It has been THE GAME I want to play with me, and all of my good friends (about 5 in number).
But I cant.

Multiplayer. Bugs.
Basicaly, come November of 2015, we get PLANETS. Hooray? With this came a legitimate mound of bugs, and glitches, and crashes. Expected. But, these still exist, if not changed in number, increased. Me and friends can not properly play a freaking SURVIVAL MULTIPLAYER IN THE DEEP PITS OF SPACE WITH NOTHING FOR MILES without rubberbanding to Asgard and back. lets not mention the hell of planets with 5 other people on in one area.

All other games handle concepts like this with no issue, AT ALL. Why cant SE?

KHS, Please fix this. I love SE, dont make me uninstall it.
I have hope, guys!

SpEn has a lot to it. It's an amazing world with absolute player's freedom. I remember thousands of great in-game moments. And this could be my most favourite game for the whole my lifetime...

But gameplay development isn't being thought out (KSH introduces just what seems the most fun and arcade. Once they even introduced randomly appearing and exploding dogs, with no backthought of instead redesigning communications and introducing some kind of navigations).

And multiplayer, the reason of this game should be played, is completely dead (the whole netcode, server interface and data management were randomly put up together, periodicaly breaking down with whole dedicated servers, hosted on huge dedicated machines).

And physics. They were exploding my ships, that I've been working on for many weeks, for years. Killing my character million times.

The most fun part - devs say, that they are trying to fix physics and multiplayer. Well, now I believed them for the last 2.5 years. Now I'm just too tired to continue to hope.

There was no code improvements or reworks even by a tiny bit. Single fix of a single older bug brings bunch of newer bugs. It's not even a metaphore. It's the real development proccess. Sometimes I even think, coders put bugs in on purpose, to just fix them later, for the work proccess imitation.

Why is it so? Well, my guess is, teamwork became hulking. KSH grown out in a bigger studio, but it's leaders stayed as small-team leaders, unable to control and monitor their coding forces with required flexibility.

Posted: October 8
The game is no longer playable for me due to one simple reason. 5:4 is NOW an unsupported ratio. Hence they dont have a UI Scale set for it. So half the damn buttons arent even on screen so whats the point of trying to play?

This game didnt even make it out of Early Access before it took a ♥♥♥♥ over its consumers. Abandon some players along the way, Failure to optimize drives away some more players. People hurt because they feel lied to and betrayed simply forget about it. And Space Engineers dies in Early Access, while profusely claiming otherwise.

Tell me Keen, If I cant play it because you no longer support something you did when I bought in does that count as "Forever In EA"? Valve you need heavier regulation on the Early Access platform.

I really wanted to try this game out, I ignored all of the recent negative reviews, boy was I wrong. Got my specs well over minimum requirements, 1 fps unplayable, even menu lags. Seems like they released some updates which preformance wise makes it unplayable for some people. I am now depressed :c

I suggest waiting till they fix this issue.

This is an amazing game, probably the game I was waiting for for years however the optimisation is by far and really the WORST Ive ever seen in a game. Try to copy 5 big ships and here you go your FPS are twice as low as they were and aslo time is much slower, 1 second in the game equal 5 seconds irl... So how am I supposed to have massive space battles... Even if the ship is on another planet, and im 2000km away, the time lag continues. It makes it unplayable and forces me to create a new world every week. My PC isn't low powered btw, I have a 1070 and a 6700K with 16GB of ram and I only hit 30fps on medium settings with just 5 ships loaded. Also the speed limit of 100ms and bad ground vehicle control... I cant recommend this game until its optimised well enough to load a few dozen of massive ships. Perhaps use minecraft Algorythm where it only render and work out ships around you like 10km away, and not THE WHOLE map like it is now. There is a render feature but it doesn't change anything... I know this is early access, but no improvment have been made in 2 years on this. So pleace change this or I assure you the game will die quickly.

This game is many things... But in it's current state I call it broken.

Hardware and software (particularly Windows 10 as I've read) compatibility issues are a serious thing for SE, I used to be able to play it a while back (although laggy due to poor hardware) and tried to again recently. First 3 attempts, BSoD... After installing latest drivers and other troubleshooting methods, the best I can get is a crash on new game. I've reinstalled and verified cache, but to no avail... It worked prior to installing my GTX 970 (if memory serves correctly)...

Intel Xeon W3530 @ 2.80 GHz
GTX 970
Windows 10 Pro (64-bit)

If it ever works again, I'll be happy to change this review... Otherwise it's going to my "Abandoned Games" category

I had a lot of fun in my 88.5hrs.

Building ships, flying through space, it was the type of atmosphere I was and still am craving, but I cannot recommend it under regular circumstances.

The game has been in development for years and years and years and still hasn't gotten anywhere, planets were added, and updates still release regularly but somehow it's wheels are spinning in the mud and it isn't going anywhere (Especially the performance..) This is the reason the recent reviews are mixed, while the overall is Very Positive.

If you crave the same thing I do, distant alien planets, the calm silence of space, and the game is 70% off, go for it. You'll enjoy the time you have in it but it will end.

They had a perfectly good running engine on DX11. Now they switched to DX12 which killed performance for me (R9 270X). Other than that, horrible interface that makes me want to just go play something else. I don't have anything else to say since these two combined killed it for me.

Worst purchase I've made in a long time.
