Mission 70 of 90Story mission
Florian Cravic is Bernie Crane now, lives in Middle Park West, and has a problem with somebody who has been threatening him in the park. The job is to drive him to Middle Park, follow at a distance while he jogs, and deal with the man who turns up.
It is the lightest mission in this stretch of the campaign and it is played largely for the comedy of Niko trailing his old comrade around a public park at walking pace.
Bernie's missions cannot be started between ten at night and four in the morning. If the marker is not there, sleep at a safehouse rather than assuming the strand is finished.
Keep some distance but do not fall a long way behind — the objective asks for both. Driving a car into the park is tolerated briefly and then fails the mission, so this is done on foot.
He attacks Bernie with a baseball bat at the viaduct, then runs for a Faggio. Taking another one to chase him is the straightforward answer; a sniper rifle will reach him from where he starts, but the shot is a demanding one.
Who this mission brings together, and the ground it covers.
