This is how we got the beast maker blueprint from raid so 2. You need to collect 3 keycards from the ai in the game. First one is after the first ladder, you have to run through and take all the left turns until everyone is dead, second is up on the cat walk at the first jump puzzle towards the back of it. The third is directly across the room up a level. You need to rush into them before they disappear out of the rooms. And the blueprint can be found in the room at the end of the 3rd jump puzzle up the ladder by the ammo depot and can only be accessed after the 3 keycards are obtained. There is 3 keycards all up and each person can only hold one. You can continue on and complete the raid or leave as soon as you’re holding it and you keep the blueprint. Also just to add some frustration you can’t die or the keycards are lost. Good hunting!
