As a veteran DMZ operator who has infiltrated Al Mazrah countless times, few locations bring me greater excitement and fear than the towering Tsuki Castle. This ancient fortress hides immense treasures for those brave enough to unlock its secrets, but it also crawls with lethal defenders sworn to protect what’s inside.
In this extensive guide, I’ll share hard-earned insights on battling your way inside to secure exotic weapon cases, valuable intelligence, and top-tier blueprints capable of shifting the tide of your DMZ campaigns.
DMZ 101: High Risk, High Reward
For newcomers, here’s a quick primer on DMZ mode. This open-world narrative experience drops operators into the war-torn streets of Al Mazrah with a major goal: secure weapons cases and extraction Intel to unlock the most lucrative sites holding exotic loot.
You only keep what you extract via helicopter, vehicle, or infiltration points. And with finite lives, permadeath is always one wrong move away. It’s an addictive loop of scavenging deadly zones, building riches and power for your operator.
Key Facts
- PvEvP environment against AI enemies and other players
- No loadouts, scavenge weapons/gear from loot crates
- Extract weapon cases, keys, intel documents to progress
- Permadeath system limits total lives for operators
- High risk, high reward – lose everything by dying before extract!
Now let’s see why the Tsuki Castle Fortress Key is so invaluable for ascent in DMZ…
Inside Tsuki Castle’s Vaults
I still remember the first time our squad fought towards Tsuki Castle, ominous and imposing, unaware of the immense power locked behind its stone walls.
Located central Al Mazrah, surrounded by nearly impenetrable cliffs, Tsuki Castle dates back centuries as both a royal palace and fortress against sieges. Even modern aerial weapons and explosives failed to penetrate it during the quarantine, leaving much of the interior strangely untouched even as war ravaged the rest of city.
It didn’t take long for scavenging factions and operators to rediscover Tsuki Castle and detect strange energy readings from within hinting at lost relics. But breaching the main gates and even bypassing exterior locks with breaching charges revealed little.
Deeper inside we discovered shielded doors marked with mysterious emblems beyond current hacking tools and keycards. Only when a squadmate clutched an odd engraved key from a High Value Target did we realize what it unlocked…
Priceless Intelligence
The Tsuki Castle Fortress Key opens access to hidden vaults and strongrooms within the central keep that were seemingly designed to withstand all criminal and military-grade cracking technology.
Inside, we discovered stockpiles of the most advanced Weapon Cases seen in Verdansk or Al Mazrah. I’m talking exotic blueprints augmenting weapons into elite marksman rifles, high-capacity LMGs devastating at range, and rapid-fire SMGs able to shred even juggernauts.
Even a single case extracted could permanently upgrade my loadout potential. Yet there were racks upon racks still sealed, hinting at armories we hadn’t even scratched the surface of.
Secret Societies
We also uncovered clues at strange organizations operating in the shadows of Verdansk and Al Mazrah influencing events. Fingerprint locks, retinal scans, specialized keys – clearly no expense was spared securing this intel that could expose those who rule from the darkness.
I discovered prototypeSz-ROM military tech before seen only in rumors. Who had smuggled this out of" Building 21? Networking maps hinted at covert communication lines we could tap or disrupt. Financial data tied seemingly unrelated High Value Targets together. Truly this intelligence was invaluable to understanding the hidden power struggles behind the DMZ crisis.
Perks of Power
And the riches inside weren’t just monetary and material. In a vault adorned with cultish iconography and pre-Ghazwan texts we finally found an extraction ticket worth more than gold – the Jailbreaker Intel.
Jailbreaker permanently unlocks all loot previously extracted across an operator‘s entire DMZ campaign. I cannot put a price on having immediate access to exotic weaponry and equipment the second I reinforce across future infiltration attempts.
The power shift cannot be overstated. No more wasted missions scavenging just to build a loadout capable of hitting bigger targets like Building 21 or Cliffside Village. I could run top-tier blueprints on day one insertion. It was like prestiging with all my hard-earned rewards still in inventory!
Securing the Loot
Clearly the Tsuki Castle Key provides access to game-changing wealth and power. But first you must find and extract this key, evade lethal enemies and rivals to reach the fortress gates, and battle your way inside facing unknown dangers for the epic prize.
Here are my hard-tested tactics for overcoming each step in this journey:
Finding the Key
The Fortress Key drops randomly at a ~2% rate from:
- Eliminating AI enemies (1 in 50 chance approx.)
- Completing High Value Target contracts (10-15% odds)
- Looting contraband caches or jackets (Under 5% drop rate)
I recommend focusing firepower on HVTs as they have the best key drop chance. Cluster your attempts around central Al Mazrah hotspots where targets frequent. With luck you’ll clutch the key and can immediately push to breach Tsuki.
Approaching the Castle
When geared up and ready to infiltrate, plot an approach clearing buildings and high grounds surrounding the courtyard to take out exterior guards.
Then breach the main gate, using suppressed weapons and grenades to swiftly overwhelm interior defenders before they can flood your entry point.
There are side stairways allowing roof access to establish overwatch of the central yard which I recommend having a squadmate lockdown.
Clearing the Vaults
Fight room-to-room inside towards the shielded central vault door. Use shotgun breachers or C4 charges to burst past barricades and catch enemies inside by surprise.
Finally at the vault entrance, equip the Fortress Key and unlock your rightful prizes. But don’t linger! As defenders swarm to protect the motherload. Toss smoke grenades to screen your squad while ransacking weapon cases.
Mark extraction routes ahead of time so the entire team quickly pushes out. Having an exit plan is key to preventing being pinned down and losing it all. Prioritize survival over greed when escaping with these rare goods!
Conclusion
The Tsuki Castle Fortress Key provides access to the most valuable weapon cases and extraction Intel found anywhere in Al Mazrah. Smart operators make acquiring and using this key a top priority due to the game-changing loot within those unbreakable vaults.
Hopefully this extensive guide has prepared you to battle through hordes of deadly enemies, breach the fortress gates, unlock the ultimate riches inside, and escape to extract your rightful prizes out of DMZ.
Soon you’ll have all the wealth and power needed to expose the hidden puppet masters and war profiteers that doomed Al Mazrah…and maybe someday even Verdansk. See you on the battlefield!
