Raven Door Codes (ZombiU)

Qyeezye
you can easily find them, you use the scanner more often, look at the walls more closely, The game is good, I liked it. Not a big puzzle with codes from the doors, but it is even more addictive, my rating is 8/10. You ask why such an assessment !? I really liked the game, but the zombies are very simple and kind, you could have made more evil zombies.

there is a tablet pumping according to the plot! then you study the white traces in the places near the door with your tablet!

ps some doors can only be opened with a 3 leveling tablet!

And how to pump the tablet? Or does it pump itself? I pumped all the weapons on the workbench, but where and how to pump the tablet did not understand?
