A player in the online shooter charged with a serious mission: to rescue people alive in a city teeming with zombies. I hope the poor man, marked with a red arrow, only sniper accuracy arrow sitting in a helicopter. To control using only the mouse (LMB - fire RMB - sight). Try to aim and the shot to the head of undead zombies to put one shot. Do not let the monsters to the character marked by the arrow. Circling around in a helicopter, kill zombies and save mankind. Good luck and have fun!
