Edit: Looked at all the endings on youtube, and I got maybe 4 of them on my last playthough.
Not a very good question, because you didn't put an effort to understand the drug problem that Jayden is facing....
From Wiki:Norman Jayden
is an FBI profiler
sent to support the police force with their investigation into the Origami Killer. Jayden possesses a set of experimental augmented reality
glasses called an "Added Reality Interface", or ARI. It allows him to rapidly investigate crime scenes and analyze evidence. He is also struggling with an addiction to the drug triptocaine
. He is voiced by and modelled after Leon Ockenden
The ending you saw, the tanks coming alive without the ARI glasses, it's a sign that Norman Jayden is consumed by the drug. He supposed to quit it and in the game, you're supposed to make him quit. Of course, if you choose not to, then Jayden will be hooked on it....
