Blake is a tough one. When he attacks he'll appear on cam 7 and try to cut your computer and phone connection. when he is attempting this though, an arcade screen on cam 7 will flash colors before landing on one. When this happens. Click the color button in front of you that corresponds with the button on the arcade screen and then press the badger call button to your left. This will lure Blake to you and stop him from cutting the connection. You do not have to be on cam 7 to call him.

Your phone's internet bar in the top right will slowly drop when he is attacking, from green to yellow to red to gray to no connection at all. The lower the bar is the higher you'll need to prioritize Blake. If Stone covers the camera and therefore the arcade screen, lower your panic quickly then look at the camera again.

Blake also has a few non-agressive phases, being when he sits in his chair, when he is walking to the server room and when he is on camera 7 but the arcade screen is not showing a color.

These are all the tips I have. Good luck!
