We are coming to and end to the keys we have allocated for this phase of the beta. There will be other chances in the future to gain access to it.
The goal of this phase is primarily to monitor server and player performance in a controlled environment. We also wanted to pick up several players new to the game so we could watch and read their feedback on the hints system. So far it has been very successful.
We are continuing to look at further optimizations we can make and work continues on squishing bugs under heel. The next phase which will be more open will be for us to monitor for any critical bugs and hardware issues. We'll be talking about it in the near future.
