Unova is a weird place. Back in 2012, when Game Freak dropped Pokémon Black Version 2 and White Version 2, people weren't sure what to make of it. It wasn't a "third version" like Emerald or Platinum. It was a direct sequel. If you’re looking for a Black Version 2 walkthrough, you aren't just looking for a list of gym leaders; you're looking for a way to navigate what is arguably the most content-dense region in the history of the franchise.
Honestly, the opening hits different. You aren't starting in Nuvema Town. You start in Aspertia City, tucked away in the southwest corner of the map. It's a localized feel. Your rival, Hugh, is obsessed with a Purrloin, and the stakes feel weirdly personal right from the jump.
The Early Game Grind and the Aspertia Shift
Most people expect the first gym to be a cakewalk. In this Black Version 2 walkthrough, the first thing you’ll notice is that Cheren—yeah, the rival from the first game—is now the Gym Leader. He uses Normal-types. If you picked Snivy, you’re going to have a rough time against his Work Up/Tackle combo.
You need Riolu.

Go to Floccesy Ranch. It has a 5% spawn rate. It’s annoying. You’ll run into a dozen Mareep and Patrat first, but stick with it. Lucario is basically a cheat code for the mid-game, and getting one this early changes the entire trajectory of your run. After you beat Cheren, you head to Virbank City. This is where the game actually starts to open up. The Virbank Complex is a massive industrial zone where you can catch Magby or Elekid depending on your version.
The pacing here is fast. You go from a schoolhouse gym to a literal rock concert in Roxie’s Gym.
Navigating the Mid-Game Difficulty Spikes
The leap from the second to the third gym is where most players get tripped up. You take a boat to Castelia City. It’s huge. It’s the first time Pokémon really tried to do a 3D urban environment, and even today, the scale feels impressive. You’ll spend a lot of time in the sewers—gross, I know—chasing Team Plasma.
Team Plasma has changed. They aren't just "liberating" Pokémon anymore; they’ve gone full pirate. They have a giant flying ship called the Plasma Frigate. This isn't just flavor text; you actually have to board this thing multiple times throughout your Black Version 2 walkthrough.

The Gym Leader Gauntlet
Burgh in Castelia is easy if you caught a Growlithe in the complex. Elesa in Nimbasa City? Not so much. Her Volt Switch tactic is legendary for ruining "deathless" runs. You need a Ground-type. Sandile is your best friend here. If you don't have a Krokorok by the time you hit Clay’s gym in Driftveil, you’re basically asking for a loss. Clay’s Excadrill is a monster. It’s fast, it hits like a truck, and it will outspeed almost anything you’ve caught up to this point unless you’ve been doing some serious EV training.
The Plasma Frigate and the Legendary Hunt
The back half of the game is where the story goes off the rails in the best way possible. You aren't just collecting badges. You’re trying to stop Ghetsis from freezing the entire region with the Kyurem cannon.
The Black Version 2 walkthrough takes you to places the original games never touched. Humilau City is a tropical paradise that feels completely detached from the industrial vibe of the rest of Unova. Marlon, the final gym leader, is so laid back he doesn't even seem to care that the world is ending. He’s a Water-type specialist, so if you haven't evolved that Magneton into Magnezone yet, now is the time.
Then there is the Giant Chasm.
This is the climax. You fight through waves of Plasma grunts, face off against Colress (the scientist who is more interested in data than morality), and finally confront Ghetsis. The fight with Black Kyurem is a scripted encounter, but don't let that fool you. If you aren't prepared for a Fusion Bolt, your team will vanish. Use a Master Ball if you’re tired, but honestly, saving it for the roaming Genies or the post-game legendaries is the smarter play.
Post-Game: Where the Real Game Begins
Once the credits roll, most Pokémon games are over. Not this one. This is why people still play it. The amount of stuff to do after the Elite Four is staggering.
- The Nature Preserve: If you see every Pokémon in the Unova Pokédex, you get access to a hidden area where a Shiny Haxorus is just... sitting there. Waiting for you.
- The PWT (Pokémon World Tournament): This is the greatest feature ever cut from the series. You can fight every Gym Leader and Champion from Kanto, Johto, Hoenn, and Sinnoh. Blue, Lance, Cynthia, Steven—they’re all here with updated teams and competitive AI.
- Join Avenue: It’s a mall you manage. It sounds boring. It’s actually addictive. You recruit NPCs to open shops that sell rare items you can't get anywhere else.
- Black Tower/White Treehollow: This is a combat gauntlet. It’s 10 floors of increasingly difficult trainers. If you beat the boss (Benga, Alder’s grandson), he gives you a Shiny Gible or Dratini.
Essential Tips for a Smooth Run
Don't ignore the "Memory Link" feature. If you have a save file from the original Black or White, you can sync it. This triggers flashbacks throughout the game that explain what happened to your old character and N. It also lets you catch N's former Pokémon, which have a unique sparkle and high IVs.
Route 4 is different. In Black 2, it’s a finished construction zone with modern buildings. In White 2, it’s a desert ruins site. This affects the Pokémon encounters significantly.
Check the weather. Unova has a season cycle. Some areas are only accessible in Winter when snow piles up to create ramps. Some Pokémon, like Deerling, change forms. If you’re trying to finish your Pokédex, you have to pay attention to the real-world calendar—or just change your console clock, we won't tell.

Actionable Next Steps
To get the most out of your journey through Unova, start by prioritizing your team's coverage early. Grab that Riolu in Floccesy Ranch immediately to handle the Normal and Steel-type hurdles in the first three gyms. Once you reach Nimbasa, spend time in the Join Avenue to level up your shops; this is the fastest way to get cheap healing items and stat boosters for the late game.
Make sure to interact with the Breeders on every route. Unlike other trainers, they will rebattle you every time you re-enter the area. It’s the single most efficient way to grind levels without relying on Rare Candies. Finally, don't rush to the Elite Four. Explore the optional caves like Mistralton Cave to find the move tutors who accept Shards—they provide coverage moves like Fire Punch or Giga Drain that are essential for the final push against Iris.
