Echo of War

We need to find out what happened here. And find a way to get in...
I think we should start with searching those barricades, were most of the defenders died. Look for anything that can help us turn off the quarantine mode - logs, notebooks, orders, diaries. Maybe keys or devices.

Bring everything that you will find on the barricades. Anything might prove useful.

What do we have here...
It's a log. Reports, assignments... here it is! The last record says that the commander of the defenders, Igor Otvagin, ordered to break through to the Laboratory and turn on the quarantine mode... Well, they must have succeeded in that. But how do we turn it back off?
This piece of paper that you've found is very interesting! It looks like its a death note of one of the volunteers. He wrote that they were fighting "scientists who had turned into monsters". Well, now it is clear - they must have messed up their experiments and turned into mutated beasts like those we saw in the Bestiary.
And finally, that device that you've found. I'm not a great technician, but I am pretty sure it works like my Master Key. It can control robots. Look, the buttons have labels.
It seems to be broken, but don't worry, I will find a way to fix it! Meanwhile, go to Sarbaz Baybut. He has some crazy idea again.
