Mission 43 of 90Story mission
Playboy X has money, a penthouse in Northwood and a development deal being held up by union officials who will not be bought. His answer is to have the officials killed on the construction site they are inspecting.
The site is vertical and unfinished, and the mission uses it in two halves: a sniping position at the top of a building, then the ground.
Playboy's car in the alley is the mission's armoury — a sniper rifle, an assault rifle and grenades. Collect from it before going anywhere near the site.
Take the lift to the top of the building and use the rifle on the lookouts standing at the ends of the cranes. It is also worth spending a few more rounds on whatever else is visible from up there: every guard dropped now is one fewer at ground level.
The union leaders are marked in red on the radar. This half is an automatic-weapon fight with a lot of men in it, so use the scaffolding and the pours as cover rather than crossing the open floors.
The final leader arrives with protection, so this is a firefight rather than an assassination, and the grenades from the car are what the group around him is for.
Who this mission brings together, and the ground it covers.
