Capek's Zoo
Capek's Zoo is the 10th level/chapter in the Red Faction single player campaign. It consists of four individual maps and begins with Parker entering a series of caves where the true depths of Capek's depravity is on full display. Capek's Zoo is followed by L11:Capek's Inner Sanctum.
L10S1: Capek's Zoo
Capek's Zoo opens with Capek teasing Parker that he's arrived at feeding time. Two large gates then open and reapers pour out to chase you. The large cavern you're in has an Jeep/ATV with a turret you can use and you can choose to drive this through the level. As you progress through this level, Parker will fight through guards and be introduced to Mutants. This section ends as Parker continues through the cavernous corridors.
L10S2: Icy Underwater Cavern
L10S2 starts as Parker continues his way through caverns in the Jeep/ATV or on foot, eventually reaching the icy caverns that give this section its name. Eventually you'll reach a retractable bridge that contracts as you approach. You'll have to exit the [[ATV] Jeep/ATV]] before proceeding forward. The intended path is to dive into the water through the hole in the ice between the two sections of the bridge, encountering a whale as you enter the water. You'll load into L10S3 as you dive down into the icy underwater cavern corridor.
Note: Alternatively, you can create a path up to the other side of the retractable bridge if you have enough explosives but this geo strategy is a bit more difficult than the optional geo-path in L9S2.
L10S3: Icy Sub Bay
If you took the intended path through L10S2, you'll load into L10S3 as you continue through the icy underwater caverns. Following the lights on the wall/floor is a good way to ensure you don't get lost. You'll eventually make your way into a large underwater room with another whale and an underwater sub-bay. The sub-bay is heavily guarded inside but there's a button inside you can press to deploy a submarine to make your way forward a little faster. Exiting the sub-bay in the Submarine, it can be pretty difficult to re-orient yourself to which tunnel is the way forward. The way forward is a through a cavern tunnel which leads downward, not the cavern which leads upward. Continue through this cavern downward and you will face an enemy submarine and another whale before loading into L10S4.
L10S4: Worm Food
L10S4 opens as you continue through the icy underwater caverns. Eventually you will reach a dock where you'll need to exit the Submarine. The area around the dock has several guards to fight through. Adjacent to the dock area, you'll find a large elevator. If you try to press the button to use this elevator, Capek will tease that he will not make it that easy. Instead, you'll have to follow the cave into a corridor opposite the dock. On the right wall you'll see a hole with bars across it. This is the way forward. You can continue down the corridor if you want to explore and it will eventually load you back into L10S2 before you reach the retractable bridge which will now be extended.
Entering the hole in the cavern wall through the bars, as you continue down this pathway, Capek will message you teasing you that "This is the feeding chute...". Nevertheless, this is the only way forward so you'll need to continue down the chute until you reach the end and drop into a large room where you'll meet the rock snake. The Rock Snake spits slime which can hurt Parker and if you get too close, it can do a melee attack that does high damage. You'll want to stand back and shoot the snake in its mouth then watch out as it falls to the floor.
From the rock snake fight, you have two choices: 1. Continue through the corridor that was behind the Rock Snake. If you go this way, you'll head down this corridor and see on the right where the non-functioning elevator Capek teased you about presumably leads down to. You'll see an envirosuit scientist as you head forward before loading into L11S1. 2. Open the grate the snake was in to take an alternate route which leads to a second rock snake. If you choose to go this way, you'll need to kill the second rock snake then shoot out the glass to its habitat. Jump into the corridor on the other side of the window and head down the corridor and you'll load into L11S1.
