This man went into first person shooter mode

It sounds like you're referring to a humorous situation where someone, likely in a stressful or intense moment, suddenly felt like they were in a first-person shooter video game!

In this hypothetical scenario, the person might start thinking and acting like a character in a FPS game, such as:

• Using phrases like "I've got a clear shot!" or "I'm taking cover behind this wall!"
• Moving with a sense of urgency, as if they're trying to complete a level or escape from enemies
• Focusing on their surroundings, scanning for potential threats or obstacles
• Possibly even using exaggerated, over-the-top movements, like dodging and weaving around "enemies" or "obstacles"

Of course, this is all just a playful exaggeration, and I'm sure the person in question didn't actually transform into a character from a video game! But it's fun to imagine the scenario and the humorous reactions that might ensue.
