Let’s be honest: Biohazard is, without a doubt, the crown jewel of Capcom’s IP portfolio. Since its debut in 1996, the series has spawned countless iterations, and even after nearly three decades, it remains a cultural titan, with fresh entries still hitting the shelves today.

Among this sprawling legacy, a new title has recently caught my eye: 'Biohazard: Survival Unit' (hereinafter 'Survival Unit'), developed by the Korean studio JoyCity. Since its global launch late last year, it has topped the App Store charts in 15 countries and surpassed 5 million downloads. With its domestic service finally kicking off on the 5th, I decided to dive in and see what the fuss is about.

As mentioned, 'Survival Unit' takes place in a parallel timeline. You step into the shoes of a young protagonist searching for their missing parents in Raccoon City, only to wake up in a hospital after a series of unfortunate events. You are quickly thrust into a city turned to hell, mirroring the original's grim setting. With guidance from series icons like Claire Redfield, Marvin Branagh, and Jill Valentine, you establish a safe house, and the core loop begins: fortify your base, fend off the undead, and expand your influence.

Playing through the early stages feels less like a typical strategy game and more like a lost spin-off from the early days of the franchise. You’re treated to action-oriented segments where you gun down zombies and solve environmental puzzles. The game is packed with nods to the classics: fixed camera angles, the iconic door-opening loading screens, and zombies that slowly turn their heads while feeding on flesh. Even the RPD station’s goddess statue puzzle from Biohazard 2 makes a return, showing a commitment to the source material that fans will surely appreciate.

The strength of 'Survival Unit' lies in its ensemble cast. Beyond the heavy hitters like Jill, Claire, and Leon S. Kennedy, it even gives us a chance to save characters who met tragic ends in the originals—Marvin Branagh, for instance, is alive and well here, ready to join your ranks. These 'What If' scenarios offer a fresh perspective that keeps things interesting.

Once you secure your safe house, the game pivots into a full-blown SLG. JoyCity has been in the strategy business long enough to know what they are doing, and it shows. You’ll be upgrading warehouses, barracks, mills, and farms to hoard resources while leading troops to purge nearby zombie threats. There’s the usual asynchronous PvP, alliances to join, and, though I haven't reached it yet, large-scale faction wars that seem to be on the horizon.

However, an SLG alone isn't enough to stand out these days. 'Survival Unit' tries to differentiate itself with exploration and combat stages. As you follow the mission path, you’ll unlock new facilities by physically exploring buildings—a nod to the action-adventure roots of the series. You’ll be fighting off hordes and solving puzzles, which adds a welcome layer of engagement.

There are also dedicated combat stages that emphasize strategy. In these defense-style encounters, you position characters to hold off zombies coming from multiple lanes. It’s not just about spraying bullets; you have to use character-specific skills, build barricades, and—most importantly—manage your flashlight. If a path isn't illuminated, your hit rate drops significantly. Deciding which lane to light up while juggling skill cooldowns adds a layer of tactical depth I didn't expect.

Let’s talk about the dreaded 'Monetization'. The game relies on the usual suspects: construction speed-ups, character gacha, and skins. For the gacha, you can pull either full characters or fragments, with 10 fragments earning you the full unit.

While the 0.5% drop rate for a legendary character might sound stingy, the 15% rate for fragments feels much more forgiving. Furthermore, the game showers you with gacha tickets through missions. I’ve only been playing for a day and already have a legendary unit to my name.

The VIP system is also worth noting. While you can pay to climb the ranks, you also earn VIP points simply by logging in. It’s a rare nod to the free-to-play crowd: persistence actually pays off.

As your VIP rank grows, you unlock special shop items and bonuses like increased resource production and construction speeds. You’ll need 'Gems' to activate certain perks, but these are easily farmable through in-game missions.

All in all, 'Survival Unit' is a competent blend of authentic series fan-service and a compelling 'What If' narrative. Even without hitting the endgame faction wars, JoyCity’s pedigree in the genre ensures a satisfying experience. Whether you’re a die-hard Biohazard fan or just an SLG enthusiast looking for something fresh, this is a solid choice.
