If you follow the main mission, you'll eventually come to the Polaris HQ, then the Talon HQ, and then the Zirax HQ. In Zirax HQ, you'll be sent to the portal "Fight Simulator Program." Mission "Kill the Boss of Wave 1" is active After clearing the open field and clearing the open access opposite the entrance, the situation seems to be stuck. No boss appears. But maybe you have to solve a puzzle here? The four towers each have four symbols with a number of skulls from 1 to 4. Inside the towers, there are switches. All of them can be turned on and off again. Maybe, the path continues behind the brown security doors. However, these cannot be opened. Perhaps this has something to do with the switch position of the towers, but then the mission objective would be to "get into the facility". Is this even just a puzzle? Or have I just forgotten something? What's the next step here?
