Look, the first time you walk into that dining room in Dulvey, Louisiana, it feels like a fever dream you can't wake up from. You’re Ethan Winters, a guy who is woefully unqualified for this, looking for a wife who’s been missing for three years. It’s messy. It’s cramped. Honestly, it’s some of the best survival horror Capcom has ever put out. But if you’re looking for a resident evil walkthrough biohazard fans actually use to stay alive, you need more than just a map. You need to understand how the game tries to break you.
Most people treat this like an action game. Big mistake. Huge. If you try to play this like Resident Evil 6, Jack Baker is going to turn you into a human hood ornament within ten minutes. This isn't about being a hero; it's about being a scavenger who knows when to run.
The Guest House Is a Trap
The opening of the game is a linear nightmare designed to set the tone. You find Mia, things go south, and suddenly your "wife" is trying to perform unlicensed surgery on your hand with a chainsaw. Here is the thing: don’t overthink the combat here. In the attic fight, you just need to keep your distance and aim for the head.
Wait.
Actually, the real trick is the hatchet. You’ll find it after the first encounter. Use it sparingly. You don't have enough ammo to miss shots, and in the "Guest House" phase, the game is basically on rails. You just need to survive until the dinner scene. That’s when the real game—and the real frustration—starts.
Managing the Baker House Without Crying
Once you’re out of the crawlspace and into the Main House, the "Resident Evil Walkthrough Biohazard" experience truly begins. Jack is stalking you. He’s loud, he’s fast, and he’s incredibly persistent.
Pro tip: Do not waste your bullets on Jack while he’s roaming. It won't kill him. It just pisses him off and wastes resources you’ll desperately need for the Basement. If he sees you, run to a safe room. The door to the laundry room is your best friend. He can't get in there. It’s like a magical barrier of safety protected by the power of dirty socks and save points.
The Shadow Puzzles and the Shotgun
You’re going to find these pedestals with spotlights. You need to rotate junk until the shadow matches the picture on the wall. It’s classic RE stuff. But the real priority is the M37 Shotgun. You’ll see it on a statue in the Main Hall. To get it, you need the Broken Shotgun from the Grandma’s Room on the second floor. Swap them out. If you take the working one without replacing it, the door locks.
Don't be the person who gets trapped in a room with a locked door because you wanted a shiny boom-stick.
The Molded: Your Real Worst Enemies
While Jack is the face of the game, the Molded are the actual roadblocks. They’re slow, but they’re tanky. If you’re playing on Normal or Madhouse, aim for the head. If you miss, you're dead. Seriously.
- The Basic Molded: Go for headshots. Two or three should do it.
- The Blade-Arm Molded: Watch the horizontal swings. They have a longer reach than you think.
- The Fat Molded: These guys barf acid. It sucks. Use your enhanced handgun ammo or a remote bomb.
Kinda gross, right? The game thrives on this visceral, wet sound design. Every step in the Processing Area sounds like you’re walking on raw steak.
The Dissections and the Chainsaw Duel
The fight in the Dissection Room is the first real "skill check." Jack has a giant pair of motorized shears. You have... hopefully some shotgun shells and a prayer.
You have to use the hanging body bags to stun him. Kick them into him. When he kneels, that’s your opening. Mid-way through, he’ll grab those shears. This is when you grab the chainsaw. It’s a rhythmic fight. Block. Attack. Block. Attack. If you don't block, you're going to see a "You Are Dead" screen faster than you can say "Welcome to the family, son."
Marguerite and the Old House
Marguerite Baker is a different kind of horror. She’s all about bugs and long limbs. When you get to the Old House, your focus shifts to the Burner (the flamethrower). You have to find the two pieces—the nozzle and the grip—out in the shacks.
The boss fight with Marguerite in the Greenhouse is arguably the hardest part of a resident evil walkthrough biohazard run. She climbs on walls. She jumps through windows. Honestly, it’s terrifying. Use the solid fuel and the burner to clear out her "nest" (her stomach area). Stay mobile. If you stay in one spot, she will drop from the ceiling and ruin your day.
The Choice: Mia or Zoe?
Look, from a gameplay perspective, this choice matters for the ending, but from a survival perspective, it changes who you fight later.
If you choose Mia, you get the "good" ending. If you choose Zoe, well... things get even bleaker. Most players choose Mia on their first run because, hey, she’s the wife. But Zoe is the one who’s been helping you the whole time. It's a bit of a moral toss-up that Capcom threw in to make you feel bad.
The Wrecked Ship: A Change of Pace
Suddenly, you’re playing as Mia. No weapons. No items. Just a flashlight and a lot of regret. This part of the walkthrough is about stealth. You’re navigating a rusted-out tanker, dodging Molded in cramped hallways.
The key here is the Remote Bombs. Save them. Don't use them on single enemies. You’ll need them for the stairwells when three or four Molded spawn at once. You also need to find the Corrosives to open locked doors. It’s a scavenger hunt in the dark.
The Salt Mine: The Home Stretch
Once Ethan is back in control, you head into the Salt Mines. This is where the game stops being a survival horror and starts being an action shooter. You should have a stockpile of ammo by now. If you don't, you’re in trouble.

There are two Fat Molded at the end of the mines right before the final climb. They are the gatekeepers. Use the Grenade Launcher with Neuro Rounds to slow them down, then pelt them with everything you’ve got. Don't try to run past them; they’ll just barf on your back until you collapse.
The Truth About Eveline
The final "boss" isn't really a boss in the traditional sense. It's more of a scripted event. You inject the E-Necrotoxin, things get big and weird, and then you’re outside.
When the Albert-01 pistol drops, pick it up. It’s the only thing that’s going to end this. Shoot the face. Keep shooting the face.
Actionable Insights for Your Next Run
To truly master the game, keep these specific strategies in mind:
- The Guard Mechanic is Broken: Seriously, use the L1/LB button. Even if a monster is swinging a giant claw at you, guarding reduces the damage by about 75%. It’s the difference between dying in two hits or five.
- Don't Hoard Chem Fluid: You might think you should save it, but you should always be crafting. If you have a lot of gunpowder, make handgun ammo. If you have solid fuel, make burner fuel. An empty inventory is a death sentence.
- Check the Maps: Resident Evil maps are color-coded. If a room is red, there’s still an item in there. If it’s blue, you’ve cleared it. This is the easiest way to find those missing Ancient Coins or Herbs.
- Psychostimulants are Underrated: Use them in new areas. They highlight every item on your HUD for a few minutes. You’ll find ammo hidden under floorboards and behind crates that you would have missed otherwise.
- Crouch-Walking is Life: You can actually avoid some triggers and sneak around Jack if you stay low and stay quiet.
Resident Evil 7: Biohazard brought the series back to its roots by making the player feel vulnerable. It’s not about how many zombies you can kill; it’s about how many rooms you can traverse without losing a limb. Take it slow, keep your back to the wall, and for the love of everything, don't forget to save your game in the trailer.
The Baker family is waiting, and they don't like it when their guests leave early. Stay sharp, watch your corners, and remember that sometimes the smartest move is just to turn around and run the other way.
Key Takeaways for Success
- Prioritize the Repair Kits: Use them on the Broken Shotgun and the Broken Handgun found in the yard and the trailer. These versions are much stronger than the defaults.
- Combine Carefully: Only use Strong Chem Fluid for Enhanced Handgun Ammo or Grenade Rounds. Don't waste the "Strong" stuff on basic First Aid Meds if you can help it.
- The Basement Loop: Learn the layout of the Processing Area early. It’s the hub for several key items (Scorpion Key, etc.) and you'll be backtracking through there often. Keep the doors closed behind you to slow down the Molded.
Following this path ensures you aren't just flailing in the dark. You're moving with intent. That's the secret to any successful survival horror run. Know the map, know your limits, and keep your finger on the block button.
