People were literally saying the exact same thing to A:CM previews. Just replace Alien with Aliens.
Except there have been countless shooters based on Aliens (space marines mowing down hordes of Xenomorphs). There's never been a survival horror game based on the original film.
And for good reason. It's fun in small bursts like in the first few hours of AvP1 and especially AvP2. But in order for it to work everything has to be scripted. Gearbox did promise early on A:CM would be a tactical survival horror type game. What did we get? Don't get too excited yet.
Anyway, it's impossible for this game to be scary after how over-used the monster has become. Alien was scary because it was rarely seen and there was nothing else like it at the time. After the pathetic Alien Resurrection, AvP, and AvP:R movies followed by the weak AvP3 and disastrous A:CM is there a monster in any media more run into the ground?
They are decades too late for a game like this. And remember it's still Sega of AvP3 and A:CM and Creative Assembly of Rome 2 behind it.
