It's a bit late notice, but we are holding a playtest for the map pg_lunacy today 20:00 CET, 19:00 UK.
This is an open playtest for anyone to join. I have provided a new release which includes the latest version of pg_lunacy, and a minor tweak to give the aliens tier 2 abilities, as I haven't finished with the v1.7 features yet.
There may be another update in a couple of days as UWE are planning to release another update to NS2 in another couple of days.
