finally! 

I've added character dialogue to the game. 

Made artificial intelligence in bots much more aggressive.

The storyline has been completely revised and many logical puzzles have been added. 

Now monsters will attack you and run at you from all sides - if you don't have enough ammo that is bad, but now the ammo will respawn at regular intervals.

The main task is to get to the main server and, having gained access to it, turn it off.

Only after that you can get to the uppermost floor, where the Lisa is.

Good luck to you!
