biribirichan: Also, as I remember original avp game, when playing alien and walking on walls, there were really helpful arrow-like indicators that would tell you where the ground is (so you know you're on the ceiling and you should be ready for a sudden drop when you release crawling), I'm missing that in this version, personally.
You're describing AvP2 here.
In AvP, the Alien hud was always like this. If anything, the AvP2010 Alien hud was much more efficient than in both of those games.
People playing AvP will just have to get used to this minimalistic hud and if they'll ever get good at playing the Alien, they'll discover they don't even need that hud anymore.
