Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

We want to create a game with a vast world where you can build almost every type of vehicle and challenges that you can imagine for both yourself and other players as well. This means that Homebrew is a huge project in terms of content, systems and features and we think that Early Access will provide us with the necessary player input to shape/improve the game.

Approximately how long will this game be in Early Access?

We want to release a stable game with the planned features in it. Since we have the foundations of our game we'll be fixing bugs and adding content more frequently in future updates. Throughout development we'll also focus on implementing some community suggested aspect. We can't give a definitive release date but once the game comes out there are plans for post-release content too.

How is the full version planned to differ from the Early Access version?

Homebrew is an open physics based sandbox and for us it'll be in a constant state of development. Some content will be added, while some may be removed to improve the overall experience. To do this we'll constantly strive to make the necessary efforts while consulting with our community first.

In the about description you'll see the things that are currently in-game and the ones that are planned in the future. Since we're still early in development we'll be focussing on eliminating bugs, adding the planned features and optimization.

What is the current state of the Early Access version?

In its current state Homebrew is already a highly playable, stable and polished game. That being said it's still an Early Access title which means that bugs may and probably will occur. If you run into issues don't think twice and contact us so that we can help you and other players by fixing them.

Will the game be priced differently during and after Early Access?

The price will most certainly increase throughout development once things get more polished. The final price will be determined once we're approaching full release.

How are you planning on involving the Community in your development process?

We're always interacting closely with our community on the community hub, if you run into any issue or have a suggestion, you can always find us there. The forum at our site is the main hub of interaction between us and the players. We read as many comments as possible and take all suggestions seriously.

How to fix your vehicles after the update!

Fixing vehicles
A lot of physics changes have occurred in the latest update. If your vehicle doesn’t behave as desired don’t freak out, in most cases some minor adjustments will be needed to get you going. If you still experience issues after trying the suggestions below don’t hesitate to contact us on steam or Discord (faster response time).

What if my boat/submarine, … sinks?
In the past pontoon buoyancy increased when the pontoon was pressed deeper into the water (more submerged), since this isn’t realistic we’ve made changes to the calculations. You can easily get your vehicle to work by either adding additional pontoons or losing weight.

What if my underwater propeller is too slow?
Prior to the patch propellers didn’t work properly while underwater; this means that boats that are using regular propellers will turn a lot slower than they did in the past. This is because water is approximately 1000 times denser than air and can be fixed by either making your propeller slower or considering the use of a water propeller. Another thing that might help is using a lower gear ratio since the propeller needs less RPM but more torque while submerged.

My boat is too fast, what now?
In the past pontoons generated too much drag, since we’ve fixed this issue you’ll notice that most boats will fly through water like crazy. To fix this we advise you to tweak your thrusters so that they provide less thrust.

My car bounces/jitters, help!
Suspension physics has changed and damping force has a lot more effect than it used to. Thankfully in 99% of the cases this can easily be fixed by lowering the damping force to a value that is lower than the spring force.

My car is too slow
Due to a variety of reasons cars used to be way too overpowered, since most parts have improved by a lot it’s best if you base your designs on realistic engines and re-tweak the gear ratios depending on your craft.

Transmissions have been improved by a lot and should be ready for use out of the box 99% of the time. Depending on the engine, wheel size and vehicle weight you might want to tweak the “global gear ratio” property based on your needs, this of course doesn’t mean that you won’t be able to change the individual gears as well.

My electrical powered vehicle doesn’t have enough power
Electrical vehicles will probably be underpowered after this update. This is because the electric motor was too overpowered and we had to rebalance it entirely. Yet again this can easily be fixed by using a lower gear ratio (less RPM, but more torque).

There’s also no need in trying to hook up an insane amount of batteries like you could do in the past since the electric motors are capped to approximately 5HP. If needed we advise you to hook up more electric motors or use a more powerful combustion engine.

What if my clutch doesn’t work?
We’ve reversed how the clutch works; now a value equal to 0 means that it has traction and a value of 1 means that it doesn’t.

What if my car suddenly feels like it's on ice?
In this update we took a major step towards more realistic behavior and to do this we've changed the system that defines how wheels make traction. As a result wheels are subject to slip curves both for side to side and front to back traction.
  • If the vehicle keeps skidding left and right: increase sideways friction.
  • If the vehicle has issues with forward and backward: increase forward grip.
  • If the vehicle has understeering issues: try increasing grip on front tires.
  • In case of oversteering: increase sideways traction of the rear tires.
Why are my tires burning out so much?
In the real world a spinning tire has dramatically lower friction than a tire with speed that is lower relative to the ground. As a result if your tires start spinning (usually due to excess torque being applied) holding throttle down will just make the situation worse. In this case you can either:
  • Increase weight.
  • Increase forward traction in the property panel of the wheel.
  • Use less torque (can be achieved via gear rations/different engines).
  • Spread the torque out by hooking up more wheels from the same gearbox or engine. You might also consider to add smoothing.

[24-08-2016]New update: physics changes, new parts and more!

From the team
The new update is finally here, the feedback that we got from you guys has helped improve the game by a lot and in this post you can find a summary of the changes that have been made. You can click on of the topics below for more information:

Tuner and builder changes

Key changes:
  • Multi select is added to tuner (hold SHIFT to select multiple tuner boxes, double click to select all similar ones).
  • Changing properties has been optimized by A LOT (better performance).
  • Saving process is faster.
  • Vehicle file size has decreased.
  • Other bug fixes and overall improvements.
Multiplayer improvements

Key changes:
  • Vehicles are downloaded faster.
  • A vehicle download queue has been added; this should lower the chance of dropping and disconnecting from a server significantly.
  • Improved vehicle uploading.
  • Reduced the chance of glitching out with vehicles of others while in multiplayer (a.k.a. ownership issues).
Water physics, outboard motor and water propeller

Key changes:
  • Improved pontoon behavior.
  • Added propeller physics for underwater.
  • Added outboard motor and underwater propeller.
Wheel improvements and new wheels

Key changes:
  • Added “grip lock” to prevent vehicles from sliding at standstill.
  • Added grip curves to wheels.
  • Added rolling and static resistance.
  • Added sound effects for skidmarks (based on ground type).
  • Reworked all wheel visuals.
  • Added new wheels.
Engines and transmissions!

Key changes:

Curved plate algorithm has been reworked
As of now dents in curved plates are a thing of the past and we have to thank this to Bear Grylls since he was able to solve this issue by rewriting the underlying code of the curved plates. These changes bring plating to a whole new level and below you can see some of our test results:

Other changes
Although a lot has already been discussed, there's still a huge amount of changes that haven’t been mentioned yet, including, but not limited to:
  • Simple gearbox no longer outputs the wrong rpm.
  • Propeller audio is cleaned up properly.
  • Blade effect inverts with picth and rpm.
  • Propeller rpm decreases more slowly after throttle is released (propeller spin calculation has been overhauled).
  • Propeller blade supersonic tip effect has been fixed.
  • Fixed bugged keybinds to audio menu.
  • Joystick sensitivity now decreases/increases based on FPS value.
  • COG of exhaust has been fixed.
  • Fixed double camera switch bug (it now remembers camera state).
  • Tutorial screen can be paused again.
  • Manual clutch on combustion engines is fixed.
  • Tuned all pick ups and added new ones.
  • Added new default vehicles.
  • Fixed normal map on junk yard props.
  • Added a clear vehicles command to the chat ("clearvehicles").
Mr. Medic
We’d like to thank Mr. Medic for helping out with the math behind the physics and improving part behaviour. His feedback and insight has helped us to change things for the better and this update wouldn’t be possible without his contributions!

What if I have a problem?
If your vehicles behave weird after this update don't panic and read THIS POST to see how you can make it work with the new physics.

To ensure that no issue is overseen we'll be monitoring steam, DISCORD and our other channels even more over the course of the following days. In the unfortunate event that you encounter a bug please follow these steps so that we can release a patch asap:
  • See if you can replicate the bug
  • Be as specific as possible about the issue, the more information the better. Preferably attach your output_log.txt file which can be located in: installed directory / HB146_Data folder (right click on Homebrew in your game library, select properties and then browse local files)
  • Notify us on Steam or Discord (faster response time)

So far so good. I can build stuff which is awesome and then I can drive it as I want. Some things I would like to suggest...

Maybe instead of cubes, why not have the pipes be joined together using node like spheres? Everything can join together at one point and be nice and smooth. When it comes to adding engines or other things, same node feature, except you can add stuff anywhere on the pole. Of course anything added would remain horizontally flat unless adjusted otherwise for the neat freaks.

We have the boats. We have the Planes. And we have the cars. What about trains? Maybe later?

Really fun. Of course, it lacks some guides inside the game, you have to guess or find somewhere else what parts does what. It can be frustrating in the beginning, but when you´re catched you get addicted to it.
It´s very stable for early access game, it´s better looking than most building vehicles games.
It lacks on the physics, sometimes driving feelsreally weird, but maybe there is some way to tweak that.
Some games I seen of the samekind have some more realism on the building part, with bendig and cracking structures of the vehicle, that not happen on this one.

EDIT: The game went into alpha recently. Most of the points made in my review still apply, but I will no longer be playing this game due to optimization issues.

So im almost at the 500 hour mark... time for a real steam review.

Homebrew Vehicle Sandbox is exactly what it says on the tin. There is one large map populated with several islands that you can roam around in, and there is also a garage where you can create literally any kind of vehicle you can imagine. Their is no questline or story (as of yet), just exploring the map with wacky vehicles and your buddies on the many multiplayer servers available.

+The only limit to what you can build is yourself. Build planes, jets, boats, hot air balloons, tanks, jet-powered flying shlongs. You name it, it can be built.

+Easy building interface. The building mechanics are a cross between voxel-based and components-based, with 'pipes' acting as frame pieces which specialized components can be attached to.

+Incredibly realistic physics engine. Aerodynamics plays a massive part in air vehicles, and at least a basic understanding of real-life physics is needed to make more complicated vehicles.

+Playerbase is incredibly nice and helpful. The devs are very communicative and can often be found playing on their own servers, where you can then bombard them with questions and reccomendations for the game.

+Online multiplayer. Once you're done exploring the map, you can join an online "party" and blast people out of the air with hellfire missiles >:D

=Large learning curve due to the realistic physics. You cant just slap a few rockets on a car and fly rings around towers, a lot of tweaking and testing is required to perfect your vehicles.

=Controller support is largely incomplete, limiting controller use to the simpler vehicles.

-Button mapping is just god-awful. Homebrew implements a button-mapping system that allows you to assign keys to basic functions, and then assign those functions to components. To be honest it would be a lot easier if I could just assign keys to components, rather than this in-between system.

-Still very buggy. None of them gamebreaking, but it can be quite annoying when a vehicle ive been working on for an hour gets corrupted and no longer usable.

-Graphics arent that great (I honestly dont give a fart about graphics, but there are people out there who think otherwise).

First and foremost, it needs to be said that this game is in very early stages of development. Additionally, if you don't enjoy things like geometry, physics, engineering, aerodynamics, etc, this game may not be up your alley.

THAT SAID, I personally find this game extraordinarily brilliant.

There is a learning curve, absolutely, but the complaints that there is no information available to guide you are blatantly false. Granted, it isn't the typical bright and friendly hold-your-hand walkthrough sort of tutorial that lots of full release games have nowadays. People who are capable of reading and following directions will have no trouble, though.

As an avid, lifelong fan of all means of transportation, Homebrew has allowed me to create functional versions of daydream vehicles once confined to the realm of doodles on scratch paper.

There has never been a game quite like this one, and it only stands to improve as time goes on.

Game is a very interesting concept; you get to build custom vehicles and drive them around in a sandbox-type environment. On the surface, I really like the idea of this game. Unfortunately I have some problems getting past the distinct issues it has (as an early access):

+The game is buggy - This is to be expected, and I am really hoping that they will address these things soon
+Instructions are limited - Yes there is a "manual" of sorts, but things like not being able to delete parts once you have attached them lends to a very frustrating point where you continually have to stop and start over.
+Random freezes - Pretty self explanatory
+Limited parts options - Again, I recognize that this is an early access, and I am simply hoping that this develops over time. At current, there are only a handful of parts available for creating vehicles, which lends to a frustrating limit on what the user can create.

Overall, the game is conceptually very interesting, and I look forward to seeing it develop and address some of these issues. Homebrew, if developed correctly, could be the next combination of Minecraft and digital Legos.

Update: 01/15/15

--I highly recommend downloading the demo (which I had no clue was available at the time of purchase) from the game's website (http://www.homebrewgame.com). Personal experience will tell you far better than any review whether or not you'll find this game worth the money. --

My "no" recommendation is MUCH more qualified than earlier. The game has been streamlined a bit, optimized a lot, and shows no signs of ceasing improvement.

In addition, the developers added a link in-game to community YouTube tutorials and improved its in-game manual. The physics are still cardboard-balloonish, but I feel like they will improve with time.

In addition, as you can see below, the developers definitely care about this game and LISTEN to criticism rather than trying to squash it, which makes them ok in my book.

I still honestly think it's too rough to justify the price, but I sincerely think that could change if development continues at this pace.

----------Previous review----

My "No" Recommendation is qualified; please read the full review for an explaination.

If you're anything like me, you played Banjo Kazooie: Nuts & Bolts and fell in love with the vehicle-building system.

Ever since I played that game, I've been looking for a game that was essentially -just- the "screwing around with vehicles" aspect of BK:N&B. When I saw this on the store page, I thought I'd found it.

So far, I was wrong. It definitely has promise; don't misunderstand me. Conceptually, it really is a neat vehicle-building sandbox. But it's in rough, ROUGH alpha shape. The physics are currently of the "cardboard balloons" variety, the camera is weird and unintuitive, and the game still isn't great at explaining how to use all its features. It's not egregiously bad and it's not unplayable, but it feels like it's a very long way from the finish line.

Now, then: If I don't think it's -that- bad, why am I not recommending it? Well, because of the price. So many Early Access games do this; they take an early build and charge way too much for it. If this game was $4.99 in its current state, I'd recommend it pretty solidly, because there's enough here to be mildly entertaining for now and enough promise to keep an eye on the game. As it stands, $17.99 (or $15-ish at the moment) is just too much cash to drop on something this rough.

If the dev keeps working on it, this game CAN be the game I've dreamed of, and when it's closer to that, I'll heartily recommend it. Until then, I suggest wishlisting it and checking in every now and then to see how it's coming.

This is a great game! Even though it is an early access game, the content that you recive is quite alot!

-You can build your own frames and vehicles.
-Large open world to explore.
-Lots of parts to build with (they will be adding more)
-Decent quality for the price.

-Physics needs tweaking.
-Unlocking parts at the start can be a challenge since you need to collect orbs using limited parts. (over time this becomes easier as you unlock more parts)
-Moving around without a vehicle is slow, when you run, its like you are jogging.
-When you are building a vehicle, it can be a challenge to link parts correctly (but practice makes perfect)

Overall, i rate this game 10/10.

I highly reccomend this game to anyone who likes sandbox games. It is, personally, one of the only vehicle sandbox games where you can literally build whatever kind of vehicle you want. Wanna build a rocket? No problem. Wanna build a hovercraft? Why not? Wanna build a buggy? sure thing, and make it so that your buggy's cockpit can take off from the buggy and drop bombs on people, with two turret gunners in the back. Why not?

Since the new engine update, Best way I can sum it up -
The old version was for the kind of people who you would find in machining shop. Craftsmen and women skilled in any number of fields, pouring blood sweat and tears into their creations and contrapions. Breathing life into heaps of discarded metal and garbage. Walls lined with white boards with countless diagrams and measurements.
The new version, well, seems to have misplaced the soul it once had. It no longer has that very mechanical feeling. From building, designing or driving.
If you never played or seen the old version, you very well love its new form. But they havent even updated the guides on steam for it, so trying to learn the new system is going to be much more difficult. And the new "instuctions" are video links to youtube.

I was about to return the game at 2 hour mark but then i decided to give the game a change!

Now if you know me, im a creative kinda guy who loves these kinda "sandbox" games where you can do what you feel doing.

I always come from a hard day at school home saying "Now i can relax from all the stress and enjoy Homebrew again"

I love games when they have responsive developers and an Awesome community around it!

Im happy that i didnt return the game!
It is well worth the money!!

I feel this game is going to grow to a big game!
And i will do my best to help that come true!

- Now again to the community and the developers -

Thank you for making my days even better and less stressfull
Thanks to the awesome community who have helped to understand the game!
Thank you for the developers who have created this Awesome game and making it better!
And last but not least, Thanks to everybody for making me happy!
