Mission 19 of 90Story mission
Faustin wants Lenny Petrovic killed, which is a straightforward request with a catastrophic consequence: Lenny's father is Kenny Petrovic, and nobody in the room says so out loud.
The mission is short — find Lenny on a subway platform in South Bohan and shoot him — and its brevity is the point. Much of what follows in Broker is the bill for it.
Lenny runs the moment he sees Niko, and the man with him carries a Micro-SMG. He is the one who can actually kill Niko here, so he is the one to take down first.
He goes down the stairs or, failing that, for a Banshee parked nearby. If he reaches it the mission becomes a car chase and a drive-by rather than a shot on a platform.
Because the chase version is a real possibility, an SMG with ammunition in it and a full ring of armour are worth having before the mission starts.
Who this mission brings together, and the ground it covers.
