Orion Developer SDK Released! 12 new screen grabs from Orion Beta 1! Slight delay to the Fileplanet Closed Beta (3-day delay). It is now launching on Monday, December 7th, 2009!

Posted by Praz on Dec 3rd, 2009

We are sad to announce a slight delay in the Closed Beta event with FilePlanet. Due to some extremely inconvenient circumstances that arose in the last two days involving the flags and grenades (currently being fixed right now), we have to announce a three (3) day delay of the Orion Closed Beta.

It will now be launching on

Monday, December 7th, 2009.

However, everything else is ready. We are honestly just waiting on two files (server.dll & client.dll). So we do have some good news as well.

We are releasing the Orion Developer SDK - Release 1 early! This is a compilation of assets and references of Orion. Level Designers can get there hands on it and start messing around and making community Orion maps! We will be announcing a Level Design Competition shortly after the Public release of the game.

The Release 1 of the SDK includes a handful of level textures, world objects, vehicles, trees, our detail objects and foliage, as well as .vmf references to show how we went about and created things for our levels.

These references include:
A.) Capture the Flag demonstration ( entities and more ).
B.) Door functionality.
C.) Keypad functionality.
D.) Structure design.

We will be constantly updating the Orion SDK just like we will the actual Beta. We will be adding plenty of more content (not all of it was included as we need to re-organize a handful of it). Release 2 of the SDK is currently scheduled to release around Christmas of THIS year!

Again, we apologize for the slight delay.. but if you are a level designer - go enjoy yourselves!

We also want to thank HalfLife2.net for recently attending a few private playtests of Orion. They have written a hands on preview of the game located here:

I also personally sat down for a 1 on 1 interview with Glenn. You can read about Orion, its roots, and the future and what is coming your way in 2010!

Also enjoy some Beta 1 Media - being featured with FilePlanet and the HalfLife2.net interview:

Install it to that directory (Steam/SteamApps/SourceMods/) but in a folder called 'Orion'.

So it should appear as:

Rather have an Epic mod with a small amount of bugs than an average one with too many bugs. It is worth the wait, and i am really looking forward to its realese
