A gladiatorial arena located within a fortified PMC training facility. Ruthless mercenaries from across the globe compete in brutal live-fire combat for the entertainment of wealthy elites. The Joes could be forced to infiltrate the Arena as undercover gladiators to gather intel on COBRA's latest recruits or even attempt to rescue someone forced to fight. 

A vast military scrapyard located in the irradiated wasteland of the former Middle East. Towering skeletons of colossal war machines serve as a chilling reminder of past conflicts. The Joes could scavenge the Bone Yard for parts to repair their aging equipment or face off against scavengers or even rogue AI systems guarding the remnants of this technological graveyard.

A vast stretch of desolate wasteland stretching across what was once the American Southwest.  Scattered settlements and the hulks of abandoned military bases dot the landscape. The Ghost Riders rule this territory, and the Joes may need to negotiate safe passage or even team up with them to recover salvaged tech or escape pursuing COBRA forces. 

A sprawling network of abandoned data centers and server farms rumored to be the headquarters of the hacker collective, Hivemind.  Located deep within a decommissioned military complex, the Hive is a labyrinth of flickering screens and humming servers, a haven for digital outcasts and a potential source of invaluable intel for the Joes. 

A heavily fortified border zone separating the authoritarian Eastern Bloc nations from the remnants of the European Union. Heavily armed drones patrol the skies, and checkpoints manned by ruthless mercenaries scrutinize anyone attempting to cross. The Joes might undertake a daring infiltration mission to steal intel from a hidden Iron Curtain research facility.

A colossal decommissioned oil platform converted into a pirate haven by various rogue factions.  Operating outside the control of PMCs and governments, the Leviathan serves as a neutral ground for smugglers, mercenaries, and those desperate enough to trade with them. The Joes might have to venture into this lawless territory to track down a black-market weapons dealer or acquire a rare piece of technology crucial for their mission. 

A sprawling cyberpunk megacity built on the foundation of the once-great Hong Kong. Towering corporate arcologies pierce the polluted sky, while neon-drenched streets teem with black markets, criminal syndicates (like the Steel Dragons), and desperate scavengers. The Joes may have to navigate this neon labyrinth to infiltrate a black-market arms dealer or acquire vital information from a hidden informant. 

A hidden eco-commune nestled within a self-sustaining biodome.  Built by the Green Resistance, the Oasis serves as a sanctuary for those seeking to escape the environmental devastation caused by unchecked corporate greed. The Joes might seek refuge here after a mission or enlist the Green Resistance's help in sabotaging a COBRA operation polluting a vital water source.
