Posting this again because beta mode is actually ready now...
I've created a new B-Man branch that let you download an early version of the game's next update.
I will use this branch to experiment fixes and test features and possibly find more bugs. It's entirely optional and available to everyone.
Some pros and cons about playing in beta mode:
Pros:
See bug fixes and new content early
Smaller population so maybe more likely to get into a server
Support Spasman in his time of need and become a hardcore B-Man fan.
I will also be paying attention to my one server that will be up quite a bit, so it's a good chance to get the achievement for killing me.
Cons:
Unstable
Some maps are modified but not whitelisted yet, so you may not get XP. The game will warn you if this is happening.
The game will also state the version you have is "outdated" but in fact will display a later number then the current version. This is natural.
Anyways, if you'd like to help test the new version, this is how you do it:
1. Open your steam library, right click B-Man
2. Select "Properties"
3. Select the Betas tab
4. Click the drop down and select "beta", close the window
Steam should automatically reinstall the game, but if it doesn't you should either reinstall it yourself or restart Steam.
If you don't see a betas tab, then you will need to restart Steam.
If you wish to go back to the stable version (I use that term lightly), simply follow the instructions above again but choose "NONE" instead of "beta".
I will be running 1 test server in beta mode, but you're welcome to run a server yourself as well. The server list doesn't show servers that match your game version, so it will appear more empty then usual.
My server will be ran from the game's dev build, and I will also be shutting it down a lot to make tweaks to the code.
Thank you for helping me test, I can do most game developer stuff by myself but it's difficult to test without a dedicated Q/A team.
