This will be very hard to know, just because of how BAD my memory is. I watched this movie when I was REALLY young. I can't remember anything other then small snippets and not even that well. I just know it was scary and I wanna watch it again.
It's based in a huge building.
There are multiple people stuck in this building and the main character was a man, I think.
Seems post-apocalyptic with something with a virus?
For some reason, they needed to go somewhere in the building.
In one scene, someone was in a room that seemed to be high-tech and tried to solve a puzzle to get through.
And at some point, there were some killer dogs (robots or infected, I can't remember).
At the end, they get an antidote of some kind.
The film is not:
- Resident Evil (2002)
