Intestinal Fortitude

[edit] Pass Through the Digestive Teeth and Find Carmine

This is the 6th chapter of Act 2, Denizens. It begins after the Rift Worm swallows Delta Squad's King Raven helicopter. The player awakens along with his squad mates, but without Carmine. If the player looks to their left after the level starts, and follow the wall, they will find a Car Gold Magazine, which is a game Collectible. Upon finding this, the player can follow the pathway to the digestive teeth. To get through them, a simple roadie run or roll through would be enough, taking note to make sure the timing is right. The next set of teeth requires the player to roadie run underneath them, but if the player stops, they will be crushed to death. The player can further progress through the digestive teeth until they come across a new enemy, the Nemacytes. Kill these weak enemies, and find Carmine laying on the ground.

[edit] Avoid the Debris Wall

After the cutscene with Carmine is complete, the player needs to roadie run away from the debris wall hurtling toward them. Right before the ramp, they should look against the wall to find Carmine's COG Tags. After grabbing them, player can proceed through the area, making sure to shoot the opening in order to ensure his/her survival. After a few sections, player will find an area that can't be crossed over. Player should look above to find a car teetering off the edge, and shoot it in order to knock it down. Next, player should run across and proceed through until finding another thin membrane to cut through. The cutscene will show their character getting through safely.

[edit] Find the Rift Worm Heart

The acid sprayers of the worms digestive systems are dangerous, and can kill players in seconds. To make it through them, player should shoot the small, green nozzles at the ends to stun them for a short time. There are several sprayers throughout the area, so player should continue on, making sure to avoid the pools of acid along the way. Eventually, player will come to a large tunnel network, the Rift Worm's intestines. If players don't find their way out within a few minutes, Marcus will die from the fumes. By keep on following the tunnels that have a deep green haze, and move to holes with light (In fact, wrong "exits" are dark). Eventually player will see another thin membrane to cut open. Cut this and player will be near the sternum, which in anatomical terms means player is near the heart. Proceed through the small amounts of Nemacyte and into the first heart. Chainsaw the arteries to move on. After a short walk, player will find the second heart, which has three arteries. Cut them, and keep moving. The third heart has a small amount of Nemacyte guarding it, but normally players don't have the time to kill them. Once player starts cutting the arteries, of which there are four, the room will start filling with blood. If you don't saw all of the arteries in time, the room will be flooded with blood, and you will die. Chainsaw the other two arteries, located on the other side of the heart, and the chapter will be over.

Upon beating this mission on any difficulty, players will unlock the Heartbroken Achievement.
