Bolderline is the latest game made with Urho3D by Indonesian based game studio Dolanan Games.

Bolderline is a minimalist puzzle game with colorful blocks that will challenge your brain.

Gameplay is simple. Random block pieces fall down on the upper side of the screen.

Your goal is to destroy them by arranging the bricks on the lower side of the screen with the same color to match the shape of the block.

Destroy as many blocks as you can to get more coins and unlock new colorful & cute themes.

Bolderline is available for free on Google Play https://play.google.com/store/apps/details?id=com.dolanan.bolderline

HTML5 is coming soon.

Edge of Time is a 3D action and puzzle Video Game Series made using Urho3D and other open source software. Inspired by the era of PS1 and PS2 games. The demo can be downloaded for free on itch io and gamejolt.

Please support us on our upcoming Kickstarter this 2018, follow us on Facebook to get news and updates.

Clinically Dead, the game which uses Urho3D as code base is released on Steam. It is a first person puzzle game, created by a one-man studio from Poland, the production offers unique experiences referring to the state of clinical death, unconventional and challenging puzzles as well as a psychedelic visual setting.

Clinically Dead was in the making for the last 4 years, and Mogila Games studio, which was created by Paweł Mogiła (the creator of, among others, the logical platformer Grimind), was in charge of the production. The storyline concerns death – the last seconds of life and an unnatural flow of time. In Clinically Dead, the player faces a strange and surprising reality.

The manipulation of space-time plays a decisive role. In Clinically Dead, movement itself affects time, and individual colors determine the time that is left. For example, the color blue means a low time value. The color red, however, is a large amount of time. We move not only in three standard directions, but also in the fourth, which is time.

Clinically Dead offers a total of about 4-6 hours of fun based on psychedelic reality, manipulation of space-time and demanding puzzles.

If for some people the coloring of the game is too bright, they can take advantage of an additional option (a so-called anti-psychedelic filter) and reduce the intensity of colors accordingly.

War Priest is a 3D platforming bullet hell where all enemies are dead at the start of the level, and you must revive them all and return to the altar while running away from their attacks. Featuring low-poly Nintendo 64 graphics and gratuitous manliness!

It takes place in the aftermath of a brutal holy war between sects of a fictional, monolithic religion. You are Grungle the War Priest, and you must go about the business of reviving all of those who died, but the ancient feuds still remain, and your fellow corrupted clergy will do all that they can to hurt you.

This project took about two and a half years to make. Pretty much everything except for the game engine and the sound effects were made by hand using Blender, Gimp, Krita, ReNoise, and other miscellaneous tools.

The game is available for free on my website. You may also choose your price for it on Gamejolt or Itch.io.

The game actually started off as a first person shooter, where you were constantly shooting and had to avoid killing civilians while collecting tokens by shooting a boulder into them. At some point, I realized that I would have a hard time giving the gameplay variety so I came up with a different concept.

Welcome to Urho3D new website!

Old

New

Josh Engebretson of ThunderBeast Games posted on the Urho3D group of their inhouse game engine, which combines Urho3D and Cocos2d-x and imports Unity3D content.

Here’s an image and a video of the work in progress.

Urho3D user CarloMaker generously set up a phpbb-based forum at urho3d.prophpbb.com. This is the recommended place for Urho3D related discussions from this point on. The old Google group is still available as well but is being phased out.

As Google Code no longer allows new upload of binary packages and GitHub pages or repositories are not convenient for them, all our future release of binary packages and snapshot build artifacts from Travis CI will be uploaded to sourceforge.net/projects/urho3d. The packages for Urho3D releases will be in their respective release folder. While those snapshot packages will always be available in ‘Snapshots’ folder to indicate that they are auto generated by CI build without human QA, so users who download them should manage their expectation on the quality or stability of the binaries in the package.

We have recently revamped our website while preserving its original minimal theme as much as possible. Although the appearance does not change much, under the hood we have made a number of changes to make the website design becomes more responsive and to make the documentation viewing easier than before, from large screen monitor down to small mobile devices. What makes this possible is the adoption of Bootstrap front-end framework.

We have also added two new features to the website:

1. Document-switcher which allows user to see the evolution of the documentation pages from different releases and the current HEAD revision.
2. Disqus commenting service which allows user to comment on the news post entries. Tell us what do you think by leaving us a comment.
