To be honest, it is hard to get excited for a new Alien game after the epic failure of Aliens:Colonial Marines. Sure this new trailer for Alien:Isolation looks solid and captures a good deal of the "feel" of the world of the movies but the first footage of Colonial Marines also looked pretty spiffy.
The good news is that the game will be out later this year according to the trailer so the hype cycle for the game will hopefully be a little smaller and I hope that Creative Assembly does a knock off job with it as the entire Alien franchise is a bit moribund at this point given the lack of success of the last few games and movies. Time will tell but for now we all probably need to ratchet our expectations back a few notches.
