I've recently accepted a new job and, as a result, starting from September I will no longer have time to maintain BA.

So, the plan. I'm happy to say that Decay & Floris have agreed to jointly take the project on from me, and I'm sure it will be in two pairs of good hands. Broadly speaking, Decay will maintain the balance & game mechanics, and Floris will maintain the UI & gfx. I will make a final release at some point over the summer, and pass on all decision making responsibility at that point. The exact timing will depend a bit on the engine release cycle & so on.
I won't be gone - I'll continue to moderate the forum, I'd like to join in with future LDs and I'll make the odd map on rainy weekends. I might even play, occasionally

Lastly, thank you to all the people who help make BA successful, especially BD & Nixtux, and too everyone who propped me up over the last 3 years!
