Look, the first time you step onto the Dulvey plantation, it’s not the monsters that get you. It’s the silence. Resident Evil 7: Biohazard was a massive hard reset for a franchise that had basically turned into a bloated Michael Bay action movie by the sixth entry. Suddenly, you weren’t a super-soldier punching boulders; you were Ethan Winters, a guy who probably can’t even change a tire, looking for his missing wife in a house that smells like rotting meat and bad decisions. Following a resident evil biohazard walkthrough isn't just about finding items; it's about managing the sheer anxiety of being hunted in first-person.
Most people mess up in the first twenty minutes. They panic. They waste bullets on Jack Baker when he's literally invincible in certain scripted sequences. That’s the thing about this game—it rewards the cold, calculating player more than the twitchy shooter fan. If you're looking to actually survive the night without seeing the "You Are Dead" screen fifty times, you need to understand the rhythm of the Baker estate.
The Guest House and the First Real Test
You start at the Guest House. It feels like a walking simulator. It isn't. You’ll find Mia, things go south, and suddenly you’re in a chainsaw fight. Honestly, the biggest tip for this prologue is to block. Players ignore the L1/LB button constantly. Don't do that. Blocking reduces massive amounts of damage, even from a chainsaw. Once you’re through the "dinner" scene, the real game begins in the Main House.
The Main House is a logic puzzle wrapped in a slasher flick. Jack is patrolling. He’s loud. You can hear his boots thumping on the floorboards above you. If he sees you, don't stand and fight. Waste of ammo. Run to a safe room. The game’s AI is tethered to specific zones; once you cross those thresholds, he’ll usually back off.
Managing the Inventory Tetris
Inventory space is your biggest enemy. You start with almost nothing. You’ll find the first Backpack upgrade in the Old House later, but for now, you have to be picky. Do you really need three boxes of handgun ammo and two green herbs? Probably not. Keep one slot open for quest items like the Ox Statue or the various keys.
Chem Fluids are the lifeblood of your survival. You can mix them with herbs for medicine or gunpowder for bullets. Pro tip: always prioritize medicine until you’re comfortable with the parry timing. You can’t shoot if you’re dead.

Navigating the Shadow Puzzles and Key Hunts
The progression in Resident Evil 7 is classic Metroidvania. You find a door with a snake on it; you need the Snake Key. You see a pedestal with a spotlight; you need to find an object to create a silhouette. The "Shadow Puzzles" are a hallmark of any resident evil biohazard walkthrough. Most are intuitive—the wooden statuette for the eagle door is found in the gallery. Just rotate it until the shadow matches the painting. It’s simple, yet the tension of Jack potentially walking in on you makes it feel impossible.
Then there are the Molded. These black, gooey messes are the primary grunts of the game. They are terrifying at first, but they have a massive weakness: their legs. If you're low on ammo, shoot their knees. Once they're crawling, they’re basically harmless, and you can either finish them with a knife or just walk around them. Save your shotgun shells for the ones that have blade-arms. Those guys are jerks.
Why the Dissection Room is the Hardest Part
The Dissection Room fight against Jack is where most players quit. It’s cramped. There are hanging body bags everywhere. You’re trying to get a key, and Jack is swinging a giant motorized scissor-thing. This is the moment where you have to use the environment. Kick the body bags into him to stun him. When he kneels, that’s your window.
Don't use the pistol here. It’s like throwing pebbles at a tank. Find the chainsaw in the room and engage in the duel. It’s all about timing—duck when he swings high, and saw into his chest when he’s recovering.

The Mid-Game Shift: The Old House and Marguerite
Once you get out of the Main House, you hit the yard and the Old House. This place is bugs. Just... so many bugs. Marguerite Baker handles the "stalker" role here, but she’s different from Jack. She’s more about traps and swarms.
- The Burner: You absolutely need to craft the Burner (flamethrower) here. You find the two parts in the Gallery and the Hut.
- The Hive: Don't waste flame fuel on individual bugs. Aim for the nests.
- The Crow Key: This is hidden in the outhouse area. You’ll need it to access the pit fight.
Marguerite’s boss fight in the Greenhouse is arguably the best in the game. It’s disgusting. She climbs on walls and ceilings like a spider. Use the solid ground to your advantage and keep the burner ready for when she tries to spawn more insects. If you see her belly glowing, fire everything you have at it. That’s the weak spot.
The Lucas Baker Gauntlet and the Barn
After the parents, you deal with the son, Lucas. He’s less of a physical threat and more of a "Jigsaw" wannabe. His section is full of tripwires and explosive crates. Always look at the floor. If you see a wire, back up and shoot it.
The "Happy Birthday" tape is a mandatory puzzle you’ll encounter. It’s a trial run for a puzzle you have to solve as Ethan later. Pay attention to the steps: get the candle, light the cake, don't get burned to death. In the actual version Ethan plays, you have to remember that you already know the solution, which allows you to bypass the trap that killed the guy in the video. It’s a clever bit of meta-narrative that Resident Evil hasn't really done before or since.
The Barn fight involves two "Fat Molded." These guys puke bile that slows you down and does massive damage. This is where you use your Neuro Rounds for the Grenade Launcher. Stun them, then use Enhanced Handgun Ammo to pop their heads. If you try to spray and pray here, you’re going to run out of resources before the final stretch.
The Wrecked Ship: A Change of Pace
The game takes a sharp turn toward the end. You play as Mia on a crashed tanker. This part is controversial among fans because you lose all your gear. It becomes a stealth game for about thirty minutes.
The key here is the Corrosives. These act as keys for the locked doors on the ship. Don't waste them on optional rooms unless you’re desperate for ammo. You need to find the fuse and the power cable to get the elevator working. It’s a lot of backtracking, and the Molded presence is heavy. If you found the MPM Handgun, use it sparingly. The Remote Bombs are your best friend here. Plant them in hallways, lure the Molded in, and click. Boom.

The Final Descent into the Salt Mines
The end of the resident evil biohazard walkthrough takes you to the Salt Mines. This is basically an action gauntlet. By now, you should have the Albert-01R or at least a fully upgraded shotgun.
The mines are linear but packed with enemies. There’s a specific section with two Fat Molded at the top of a ladder. This is the hardest non-boss encounter in the game. Use your Grenade Launcher. Do not try to climb that ladder until they are both dead, or they will just knock you back down into the abyss.
Finally, you reach the Lab. This is where the story clicks. You find out about Eveline, the E-Series, and why the Bakers went insane. It wasn't their fault. They were victims too. It adds a layer of tragedy to all those times Jack tried to hit you with a shovel.
Defeating Eveline
The final boss isn't really a "fight" in the traditional sense. It’s a spectacle.
- Inject the serum when prompted.
- Back away as the house literally falls apart around you.
- Shoot the face. Any gun works, but the shotgun is faster.
- When you’re knocked down, grab the specialized weapon dropped from the helicopter.
- Finish it.
Survival Insights for Madhouse Difficulty
If you’re playing on Madhouse difficulty, forget everything I just said about being "careful." You need to be perfect.
- Antique Coins: These are in different locations and are used to buy Essential upgrades like the Iron Defense Coin.
- Save Tapes: You need physical items to save your game, just like the old ink ribbons. Use them wisely.
- Parrying: You MUST master the block. On Madhouse, a single hit from Jack can put you in the red.
The biggest mistake players make is not using the "Secret/Dissected" items. If you managed to unlock the Circular Saw from a speedrun or the X-Ray glasses, use them. There is no shame in using unlockables to survive the nightmare.
Actionable Next Steps for Your Run
- Check your corners: In the Main House, items are often hidden under furniture or inside crates you can break with your knife.
- Prioritize the Repair Kits: There are two broken guns in the game (a shotgun and a handgun). Use a Repair Kit on the M19 Handgun early on—it’s significantly more powerful than the standard one.
- Combine wisely: Never use a Chem Fluid on a single Herb if you have Strong Chem Fluid available. The "Strong" version creates a full heal, which is infinitely more valuable.
- Use the Map: If a room is red on your map, there is still an item in there. If it's blue, you've cleared it. This is the easiest way to ensure you aren't missing precious ammo.
- Manage your saves: Don't overwrite your only save file right before a boss trigger. Keep at least two slots going in case you realize you entered a fight with zero health and one bullet.
