Brick Inventions is a physics based strategy/building game made in Unity 5. Basically, you have a large variety of different blocks which you can place in the world to build almost everything you can imagine. The special feature of the game is that every single block has physics - everything you build can be destroyed.

In the game, each player has a crown on a podium. If the crown falls to the ground, the player loses the game. To prevent this from happening, you have to build defenses and weapons out of blocks. This requires resources, which you get by transporting resource-blocks from a producer to a warehouse. Each producer and warehouse has a special object on a podium (like the crown). If such an object falls to the ground, the producer/warehouse loses all of its upgrades.

Since everything is created out of blocks, it may take long to build things that are more complex. The Inventor-mode enables you to create your own inventions out of bricks, which you can save and then place in singleplayer-, multiplayer- and sandbox-games like any other block. Invent a new machine, more efficient weapon or more powerful defences - the better your ideas, the better are your chances of winning a multiplayer game or mastering a challenge in a singleplayer game.

Single & Multiplayer
Brick Inventions offers both a singleplayer- and a multiplayer-mode. The singleplayer-mode consists of different levels, each featuring a different kind of challenge. The multiplayer-mode enables you to play against players all over the world. In order to win a game you do not only need to have a good strategy, but also powerful inventions - defend your crown and shoot down those of your enemy.

In the sandbox mode you can build everything you want, without limits. Sandbox maps can be saved so you don't have to worry to lose anything you've created. There is also a multiplayer sandbox mode in which you to build and experiment together with your friends.

Support the game on Steam Greenlight

In this post I want to talk about the multiplayer mode, which is one of the main parts of the game. I've also created a new video that shows the multiplayer mode:

How the multiplayer works

Those of you who have been following the game since its early days might remember how the multiplayer works. The basic idea is that (depending on the game-mode) every player has a crown which he has to protect. To win the game, the player has to shoot down the crown of his opponent. Therefore, you have to build defences and weapons out of blocks.

At the beginning of the game, each player has only some wood and stone which are the weakest materials in the game. In order to get more and better resources, you have to build producers. These must be placed near the resources which are randomly generated around the crown (actually, it’s an algorithm that determines fitting positions). These producers can be upgraded which improves the production speed.

The blocks

Besides a producer for each material, there are a number of special blocks for the strategic multiplayer mode. These blocks can only be placed on the floor and don’t have physics. Here’s an overview:

  • Material Producer: Generates resource (Wood, Stone, Metal, Gold, Obsidian)
  • Energy Producer: Generates energy (used to power accelerators,…)
  • Warehouse: Improves storage capacity
  • Market: Used to trade different resources
  • Research Centre: Unlock special blocks (see below) and bonuses (faster production,…)

Then there are special blocks that are available in every game mode. Like all standard blocks, these blocks have physics and can be placed everywhere:

multiplayer blocks

  • TNT: Explodes after 5 seconds after activation
  • Bomb: Explodes on impact or after 15 seconds
  • Accelerator: Block with rolls, used to shoot blocks away. The higher the speed, the higher the energy consumption.
  • Rocket: Block with rockets on the side, can push itself and other blocks forward.
  • Trigger: Block with detector attached to it. Can be connected to other blocks which will then be activated if something enters the detector field.
  • Gate: Used to forward signals from trigger. Can also perform logical operations.

special blocks


If you compare the multiplayer mode today with how it was about a year ago there have been several changes.

First of all, I removed the conveyor belts together with the whole transportation mechanic from the game. The reason for that is that after several test games I came to the conclusion that I looks nice but it doesn’t really add something to the game. It even made everything more complicated, especially if you have just started to play the game.

Next, I added resources-objects to the floor which adds a little bit of randomness to the game and prevents players from building all the producers at the far end of the playing field.

Previously, I’ve added numbers to the sides of producers and other blocks which gives a better overview.

Other modes

Besides the crown defence mode, there is the tower construction mode in which the players have to build towers of a specific height. Once a player has a tower that is high enough, he has to defend it for 2 minutes in order to win the game.

I’m planning to add a special version of the crown defence game mode in which you have unlimited resources. To prevent players from spamming things, there will be a block limit for each player. In addition, there will be attack and construction phases so that you have to plan carefully how to deal most damage during a small time window.

There are also plans to implement a 4 player multiplayer map (1v1v1v1 or 2v2) but that might cause problems on slower internet connections as the synchronization of blocks generates much traffic when there are many blocks moving at the same time.

Besides the competitive multiplayer there is of course also the multiplayer sandbox mode where you can build and do whatever you want.


What’s next?

I’m still working on the singleplayer levels while improving smaller things and fixing bugs. After that I will continue to work on the Steam integration which I hope won’t take too long. I'll post more news regarding the beta in the next weeks.

I'm working on several changes on the core system which will improve the gameplay (a new placement system and some other things I haven't talked about yet). Besides that, it seems as if Unity 5 will (finally) be released soon, which will give a huge performance boost and other improvements.
So to answer your question: there will be a new demo version after I completed the new systems and ported the game to Unity 5.

If the game makes it on Steam Greenlight, it will probably come to Early Access after I make sure that everything works and that the quality is good.

all games if sandbox like this (not to mention blockscape and starforge(but blockscape in particular)) stoped to update or did only minor update since the game came on steam. that is, less feature than promised and a game still in beta phase since month...

so id say, as your sandbox game seems very promising i hope what you wanted to do or promised to do at first will be done before you quite it or mass selling it on steam. :)

Quality has been very important for me since the beginning. Like you mentioned, I saw many indie games which had very interesting concepts but the quality of the games wasn't good in my opinion. That's why I waited over a year until I released a demo and I will stick to that in the future. The alpha demo far from being perfect and now, 6 months later, the game is much better than it was back then but that's okay for an alpha version.

I just noticed that the game got greenlit on Steam (if it's not just a bug as over 500 games got greenlit that day - I will probably wait a bit longer until I make an announcement) but that doesn't mean that I will just publish the game as it is now as it's not ready yet. I will continue to add content and improve the game until it reaches my expectations. That will take some more time but better to release it later than unfinished and full of bugs.

Regarding the fps view: That's something I get asked a lot recently. It's not in development at the moment and I want to distance the game from minecraft, etc. but if you guys want something like that, I could implement it in the sandbox mode (it wouldn't make much sense in singleplayer levels or multiplayer combats).

i am glad to here that :)

about the fps view i don't want a minecraft like fps view with interactions, mobs and all. just a simple fps view to move around, admire whats has been done from the inside and myabe do some parkour with traps and building falling while you have to survive from A to B. just as simple as that :)

It wasn't all bad though. Optimized parts of the positioning system - 10x performance compared to prev. version.
