Enemy Within, Winter 2003
Objectives: Escape from the sewers
Somehow your assassination mission took a couple of months, because when you return to base, its winter, and the Soviets have cleaned house in the sewers. You wont have your usual rest and respite here in the underground; instead, youll have to wade through the enemy soldiers.
Begin by killing off the soldiers on the far side of the sewer water, then cross over the wreckage and head into the tunnels. Theres something of a secret area at the first right turn; if you climb up the wooden boxes to the upper level, you can find a medic kit and a Molotov.
Proceed along the sewer tunnels until you come to a room with, oh, about a million Soviets. This is going to be a challenge on the harder difficulty levels, but luckily theres plenty of cover alongside the path, and the enemies on the far side of the water shouldnt be able to fire at you. When youve killed everyone along the first half of the room, take the ladder up to the upper level and exterminate the soldiers hiding in the compression room. Using the rocket launchers on the rest of the soldiers in the large room below should let you cross to the other side without needing to worry about getting killed while crossing the channel.
When you reach the far side of the sewer room, you can continue through the tunnels, or head down to the opposite end of the room to pick up another fully-loaded rocket launcher. Either way, youll be faced with a fork when you head into the tunnel; the left passage leads to a dead-end snipers roost overlooking a room with a few Soviets in it, while the right passage takes you through a gauntlet of soldiers packed into one long hallway. (If you took the Rocket Launcher earlier, you can spam the rockets down the hallway to clear it out with relative ease.)
Heading along the right path will take you through a winding series of tunnels. Watch your corners, and take advantage of the fact that Molotovs and grenades can bounce by ricocheting them off of walls when you spot concentrations of enemies.
The path is linear, so you can follow it along until you come across a machinegun-wielding soldier dressed out in full-body armor; even his head is protected. Hell chew you up in short order if you stay within his field of fire, so dont. Your best bet here seems to be to use a grenade; bank one or two of them off the tunnel wall and the gunner should get blasted. Hell drop his machine gun when he dies, so pick up your new toy and soldier on.
Unfortunately, theres another machinegunner right around the corner from the first, and this one is a fair distance away from you. Youll need to kill all of the grunts in the first part of the passage, then make your way into the corridor leading to the right, then bank another grenade off of the boxes near where he stands. Hell drop another machine gun, which will make it a little easier to mow down all of the rank-and-file Soviets in the area.
From this location, its a straight shot past the traffic cones to where The Kid and Bagzton are hiding out. Walk up to Bagzton to end the mission.
