I've had 2-3 epic(hour long and not drawn out) games in the last 2 days. Altair doesn't suck anymore. Bast could use a bit more work, not much was changed. Free fast upgrades are a huge boost to aliens, they seem to be winning a lot now but I'm sure that will change once marines figure out new ways to fight them.
I have heard a lot of people reporting client instability; a lot of people say they lock up for a few seconds.
