Agent John FPS Game play online

Who is that suave man in a suit?
This is his first middle surname and only given name,
Be the full action star of this full action game.
Ride a helicopter into the battleground bravely,
He hits the bad guys, he jumps, he gallops,
Possesses countless guns and ammunition.
The villains who are known as evil and terror
made the same mistake,
Forget he wiped out all evil plans
A spy ready to shoot with precision.
Gangs, guerrillas or terrorist factions,
No one can fight in front of agents!
