Fracture the Flag is now 'playable.' Which is not the same as 'release worthy.'
There are bugs. There are things that simply don't work yet. There are bits that might make you scream in frustration.
It's also a multiplayer game so unless you have a buddy who also wants to test you may not be able to play.
You've been warned...
If that still sounds fun to you then maybe you want to be one of the alpha testers?
Alpha versions will be distributed via Steam. Currently, the Steam build supports only Windows, but a Mac support will be coming shortly. If you're interested leave your computer specs (looking for all types of machines) and Steam name in the forum or in the comments below.
