This, of course, stirs the Witch from her troubled slumber. At this point, I was trying to make my way past her, standing right next to her when she awoke. She lunges with cat-like reflexes towards a teammate who was a bit behind me. She immediately knocks him down causing him to bleed out. Still on top of her prey, she gets a shotgun blast from the side and a double barrage of rifle bullets tearing into her back.
She doesn't go down easily, but is quite a bit easier to take out than the Tank. Our teammate was lucky, this time, having suffered through an instant knockdown and a sped up bleed out time thanks to the Witch's relentless assault. We continue on to the rooftop.
All Out Assault
On our way to the roof we need to pass through a level just below the actual rooftop itself. A maze like area soon greets us, with walls made out of wooden planks and steel support beams. The moment that I was trying to spend surveying the area is broken up by an attack from a Tank and a fresh wave of Infected. The Infected snake their way through the corridors to get to us, though there doesn't seem to be too many of them. That is the good news, the bad news was bursting through those wooden beams without a second thought and coming straight for us.
The wooden beams break apart and dangle from the upper steel supports in a wonderful display of environmental interactivity. One of the more intense fights against the Tank develops in this area as we four survivors dart our way in and out of the pre-made pathway, through swinging wood pieces, and into pathways carved by the Tank's brute force. Our shots rip out even more wooden beams as they sway thanks to the physics engine at work within Source.
With the tank's attack coming to an end, we make our way to the roof with no more interruptions. The roof has a raised landing pad fit for a helicopter, and also contains a building with a radio inside. We take our positions on top of the landing pad, able to look down and have a very clear view of the rest of the rooftop area, giving us plenty of opportunities to prepare for an attack. I was told that the nearby radio was the trigger, and that once it is activated the final sequence will begin. We were given a moment to prepare ourselves, checking to see that all weapons were fully loaded before a teammate activated the radio.
At first, it was just a massive assault on the helicopter pad by the AI Infected. Scores of them appeared from all areas as they made their way to the platform we were on. It was easy enough to take them out. It was easy, that is, until both a Smoker and a Boomer show up along with another wave of Infected. Our party starts to become disorganized. The plan of sticking to the helicopter pad had just been thrown out the window and it was now a mad scramble to try to pick off the enemies climbing up to our location. The Smoker is off to my left just below my position, and the Boomer was right in the middle heading towards us as fast as he could move.
Yet again, I was snagged by the Smoker's tongue and dragged towards the edge of the pad. A railing prevented me from being pulled further, however that does not mean I was so quick to escape death. The barrier halted my movement giving my teammates time to try to free me. The health was draining quickly from my player because once you're hooked by the tongue and halted by an object it just serves to tighten the tongue's grip and your character can be strangled to death where they stand, or so I was told.
