Vigilante: Free Agent

You are Ghost, a freelance operator who takes the jobs nobody else will.
In this retro FPS game, rescue a kidnapped man from an abandoned warehouse. Hold a polling unit in Gwaram, Bauchi State, when thugs ride in on okadas. Get schoolgirls out of a Niger State boarding school at night. Escort a politician through an ambush on the Benin road. Cover his swearing-in from a rooftop 200 metres away with a sniper rifle. Then board the MV Bright Star in the Gulf of Guinea, snipe the pirate skiffs, clear the ship room by room and take down Black Tide.
Earn money from each contract and spend it in Ghost’s armoury on new weapons: an SMG, a shotgun, a carbine and an L118 sniper rifle with bullet drop and a 30× scope.
Plays on computer and on phone (landscape).
