Kill It With Fire 2: How to complete all Vent Challenges

About midway through Kill It With Fire 2, DARWIN tasks you with powering a dimensional gate so you can finally end the spider menace for good. The catch? You have to squeeze your way through a vent to get a fuel cell. And it’s not the only one. Here’s how to complete all Vent Challenges in Kill It With Fire 2.

There are four Vent challenges in Kill It With Fire 2, ranging in length, difficulty, and reward. The first Vent Challenge is easy, and so far remains the only one necessary to the plot. But you can tackle the other three vents on the ship. Not only can you gain more fuel cells, but fastidious explorers can come away with rewards.

All Vent challenges in Kill It With Fire 2 and how to complete them

The first Vent challenge is tossed your way not long after completing the second dimension in Kill It With Fire 2 and busting through a door with a tank. DARWIN, the sentient tablet, says you must locate three lost fuel cells to have enough power to make it to dimension Alpha One. Apparently, the spiders have squirreled away the cells in vents and put them under the protection of powerful guardians. Yeah, it’s Alien, but with giant spiders. I don’t know which is worse.

First, here are some tips on winning the challenges:

• Abominations are the size of a bulldog and are too powerful to beat. You’ll need to sneak around them.
• Use your Radar tool to check on the location of an Abomination. Keep in mind that the range is not that far, so move slowly.
• The Vents are like mazes, so expect twists, turns, and dead ends.
• Dying is okay; you’ll lose your ammo if you spend any, but there’s no real punishment.
• Abominations have poor peripheral vision but will pause if you’re close to being seen.
• You mostly navigate while crouched, but there are places where you can stand up and sprint. Feel free to do so, as Abominations don’t seem to become alerted to noise.
• Large pipes on the ceiling often lead you to the exit.

How to complete Vent Challenge 1: Straight Shot (easy)

Items: One spacebux, one fuel cell.

The first Vent Challenge in the game is a breeze, even with the level 30 Abomination spider crawling around. You’ll find it next to the Reactor:

Now, let’s get this Vent challenge beat. Pause when you come across your first fork in the path, and wait for the Abomination to walk past you going right. Take the path to the left to the end where you’ll find Spacebux on the floor.

Wait until the spider comes back down the path and then turns around. Keep your Radar open to see when it’s moving. Walk back into the starting duct to your right and wait for the Abomination to walk by again, going left. Leave and go right. Follow the large tubes on the ceiling until you find the fuel cell and exit.

How to complete Vent Challenge 2: Choose Wisely (medium)

Items: One weapon blueprint, one fuel cell.

The second Vent Challenge, ‘Choose Wisely’, is located in the Workshop. It’s certainly tougher than the last Vent, but only due to its name: Choose Wisely. Multiple paths are beckoning you onward, and most of them contain Abominations ready to jump you.

After entering the vent, you’re soon faced with a long hallway. Some of the paths contain wandering Abominations, so keep your eyes peeled and Radar out. The paths that have spiders are obvious, thankfully. Also, with their poor peripheral vision, you can walk down the entirety of the hallway without having to avoid the spiders’ gaze.

Walk down the hallway until you reach the third opening on your left. Go down this pathway to find the blueprint for C4. Watch out for mimic spiders, though; I had to kill two of them in this room.

Leave the room and turn left. Follow the pipes on the ceiling until they turn right. Keep moving to find the fuel cell and exit.

How to complete Vent Challenge 3: Ring Around the Rosie (hard)

Items: One upgrade wrench, one fuel cell.

The third Vent Challenge in Kill It With Fire 2 is ‘Ring Around the Rosie’, located in the ship’s Armory. As you may have surmised, the challenge consists of a vent in a square shape with Abominations slowly patrolling it. They move in a counter-clockwise motion, so the first spider you’ll see will come from the left. There are also smaller spiders that throw off your radar.

After an Abomination walks past, turn right and follow it. You’ll eventually come to a path to the right, but ignore it for now. Keep going around the ring until you hit an intersection with an opening to the left. Go down it to find the upgrade wrench.

Now, go back to the ring but wait until an Abomination passes. Follow it out until you get to that turn to the right I mentioned and take the path. You’ll eventually find the fuel cell and exit.

How to complete Vent Challenge 4: The Labyrinth (impossible)

Items: One tape recording, one Spacebux, two fuel cells.

Now, the really icky part. The fourth Vent challenge, The Labyrinth, is the most difficult one yet. No, really. It’s actually going to be tougher than the “hard” challenge we had before. There are twists and turns throughout. And the worst part? You need to learn when to be patient, and when to move. You’ll find The Labyrinth in the Captain’s Quarters:

Follow the ceiling pipes until you reach a four-way intersection. Stop. Wait for the Abomination to walk by, going right. Now, head into the path and turn left. Stop when you get to the next intersection with paths going left and right. Watch the radar for the Abomination. When you see it moving away to the right, head down the left path.

Follow the path until you reach a dead end. Wait at the end of the hallway, peeking your head out until you see the Abomination coming close. Be careful, as it will kill you the moment you step out too much. Wait for it to turn around and then start moving forward. Stop before the opening to the right. Watching your radar and wait until that first Abomination stops and goes the other way.

Walk forward, following that second spider, until you reach the first opening to the left with a red light and webbing. Nestle yourself behind the web and wait for the Abomination to patrol back. As soon as it walks past you (heading right), leave and go left down the U-shaped turn. Take the first right into the alley with the red light and web. Hide there and wait for the spider to walk past, coming from the left. It’ll turn around and then go back down the hallway. When it does, leave the vent and head down the path to the right.

Stop when you get to the next intersection and peek to the left. If you see an Abomination, wait until it turns back around. When it does, leave and go right. You’ll find Spacebux on the floor next to some bones. Comforting.

Peek out and check to see if an Abomination is heading down the new path. If it is, wait for it to get close and turn around. Leave when it does, but check the path to the left for the last spider you juked. If all looks well, keep going until you can take a left down an L-shaped hall with a blinking red light.

This spot puts you in a type of square-shaped hallway, with an Abomination patrolling around. Walk until the path splits left and right. When the spider is moving to the right, take the left path. Keep going until you find your first fuel cell.

Next, go back to that square-shaped hallway, but only after checking if it’s safe. Return to the intersection mentioned above. Wait for the spider to travel away from you, going right, and then leave by heading down the right path. Follow the pipes on the ceiling and go straight. Walk until you reach the final fuel cell and exit door.

With that, you’ve completed all four Vent challenges in Kill It With Fire 2. For more, check out our guides on how to get the Minigun and all of the potion recipes in the game.
