ALIEN! MORE ALIENS! EVEN MORE ALIENS!
From the look of the gameplay video the amount of aliens you will face will be on a mass effect style level, with at least 3 aliens per square inch at this rate. Some may say that this is to much, but can you have to many aliens? In my opinion, no, but we shouldn’t judge a book by its cover, in this case we shouldn’t judge the amount of aliens by a 10 minute gameplay video.
