Firstly, Congratulations on those who started playing on public beta today. Without beta key, I'll still have some fun watching youtube videos.
There's always been curious on the amount of opponent information a player can see from game graphics and animations.
Such as the Hydralisk's range/speed upgrade, Zealot's charge.. what upgrades are visible base on the 'look' of an unit?
Also, from a video clip I see stargates morphing in carriers and you can see clearly carries is been made base on the animation. Are there other buildings that can spot which unit is coming out?
