Things are getting leaked and NOT by me so feel free to take a look. I repeat, this is NOT from me but was posted on /v/.
-The devs are cheeky and did not announce everything in the game, such as hives (

-Apothecary is incredibly OP and Assault is UP sadly
-You get unlimited ammo
-The 1 map in the beta is about an hour long. It's a mixture of corridors that are 2 Teriminator wide and extremely dark, and large rooms. Speaking of darkness, holy shit you can barely see
-The map is not linear. There are intersections where you can choose different ways to go. It's not a maze but it's far from linear.
-The motion tracker in this game is like something from Aliens. Being in a dark as fuck hall, watching your tracker while you hear the genestealers screeching coming your way is spooky as fuck
-Framedrops are really bad right now
-Hacking doors behind you to block the hordes is actually very effective, you can hear them change their route after a door is closed to get at you again
-The heavy plasma cannon jams almost every other shot
