The reason why this game doesn't work is the developers want to make a FPS when that is anathema to what worked in the films. The Aliens were deadly because the humans were at a disadvantage and victim of their own hubris and of greed in general. To make a good Alien game you have to be at a real disadvantage.
In Alien they were trapped on a spaceship where even wounding the alien could literally kill everyone onboard, with no weapons but makeshift flamethrowers and prods, and with the smartest person onboard dedicated to killing them. In Aliens they were crippled (they had to use shotguns and flamethrowers), then they lost all their equipment and had to hole up in enemy territory. In Alien 3 they were on a prison planet with no weapons.
Aliens games want to go "Yo, dude, check it out, you've got a smart gun you can fire with impunity" while ignoring that the marine's firepower being castrated was essential to the atmosphere.
And I said textures, not character models. The texture work is very spotty and this isn't a surprise considering they reused assets from a game initially cancelled in 2001. It might improve as the game goes on and more of Gearbox's work shows.
