I’m livestreaming Mari0 development if you didn’t know. The link is at the top of the homepage.
Work on Mari0 SE is progressing. I had a livestream today as a homage to our great Swedish overlord, and it was lots of fun. Here’s some things that I did today. I’ll have a video of another thing up tomorrow that a lot of people are going to like.
Platforms
Blocks that you can pass from any side except above.
Geldispenser with input
Gel dispensers can now be hooked up to any input and dispense gel according to it.
Mirrorblocks
Blocks that bounce off portal shots in the opposite direction.
Grates
These let through portals, lasers, gels and lightbridges but no other objects like the player or boxes.

Amongst all the other great additions (such as more hats, Online Multiplayer, and more hats), Mari0: Special Edition will also have a completely reworked Portal campaign, as I am unhappy with the current one.
One thing that I felt was definitely missing is a proper boss fight at the end. While the puzzles are certainly the main focus of any of the Portal games, the boss fights still held some value in wrapping up the story and giving a sense of accomplishment.
Since the community has been very imaginative in mappack creation, giving everyone a chance to design the ultimate boss battle should end up with some pretty amazing ideas.
Here’s some guidelines
Here’s an example of a good design:

Get designing!
This is a community mappack made by Baf which really sets the bar for mappacks. It has awesome custom graphics and music. Also he’s better at making trailers than we are. Check it out:
Unfortunately, this mappack is a little big for the slow DLC system, so you’ll need to download it yourself at the forum thread.
If you have a mappack, it’s a really good idea to create a thread for it at the mapping forum instead of sending us an email, as we are currently way behind on checking them and it’s unlikely we will be featuring any more mappacks as DLC before the update.
We are currently doing our best to get online multiplayer going and then add some other new stuff and release “Mari0: Special Edition” (or Mari0 SE) sometime in the future. Sign up for the mailing list to be informed when it’s done!
Just in time for today, we have a video of the work in progress online multiplayer!
Mari0 version 1.6 is up for grabs.

You know, I’m starting to see a pattern here:
- Uneven subversion: Adds features and is horribly broken.
- Even subversion: Fixes features and is awesome. I hope.
Nevertheless, this is mostly a bugfix update. It fixes the slow running on single core PCs and mappack downloading, as well as corrupted options.txt keeping the game from starting. We also have a challenging new DLC pack up:

See the full changelog after the break, as usual.
So yeah, 1.5 doesn’t run all that well on PCs with single cores. But there’s good news too: It’s not my fault!
Fix coming later today.
And no I won’t make an auto updater, because then we’d be at 3.2 before that works for everyone.
If your game is not even starting, but deleting options.txt fixes it, can you send me the corrupted options.txt (make a backup first)? I just can’t replicate it.
Have some crazy 4-player footage.
Mari0 1.5 is out! Get it while it’s hot.

Gamewise, we have two new features requested by the community: Custom backgrounds and custom music! Check after the break for a short documentation.
But maybe more interesting, we have more new DLC packs than we had DLC packs before! So that’s like over 200% the mappacks there were before. Crazy, I know.
Download 1.5 and check the DLC section in Mappacks to find the following new additions:

Changelog and short documentation after the break!
So earlier today we received an email from Anonymous contributor. He notified us that a website has appeared claiming to offer a download of Mari0 and that someone was posting the link on various imageboards and forums. Wouldn’t really matter, however this version had an additional feature that our version doesn’t: Malware.
Rude.
Since we don’t hold absolute control of the internet, we’ll just have to say this: Stabyourself.net is the one and only download source for the official releases of Mari0. If you download it elsewhere you run the risk of getting more than you ask for.
The specific site in question has been partially taken down by our request (which may seem slightly ironic), but probably not for long. I’d like to thank Tophost.it for responding so quickly.
Since the title promises a PSA, here’s some actual useful information.
Well, it has been a pretty exciting week! Mari0 is already at version 1.4 and has been getting quite a lot of attention. If you’ve been wondering exactly how much attention, this should be quite informative.
