Your team is tasked with locating a Spec Ops Commander who is coordinating the US government's response. You'll be moving through the city's commercial district, which is now a warzone between the infected, UBCS, and US Spec Ops. Expect heavy firefights. US Spec Ops are highly trained and well-equipped; they will use grenades, suppressive fire, and advanced tactics. Use cover, flank, and prioritize medics or heavy weapon specialists among their ranks.
The path will lead you through stores, offices, and open streets. Be wary of snipers in elevated positions. Utilize your own sniper rifles if available, or use grenades to flush them out. You'll also encounter more advanced infected, including Hunters and possibly a few Nemesis prototypes (though not the main Nemesis boss yet). Follow the objective marker, which will lead you to a heavily fortified building where the commander is believed to be.
