Spyworld

From BoardGameGeek:

Build. Defend. Infiltrate. Repeat. In Spyworld, every player is a mastermind determined to become the world's richest supervillain. During the game, everyone simultaneously builds their own secret headquarters by placing walls, traps, sentries, and hidden secrets while training an elite agent and collecting powerful gadgets. Every choice is a balancing act: invest too much in your defenses and your agent won't be ready for the mission ahead; focus too much on infiltration and your own lair may become an easy target. Once every lair is complete, the tables turn. Your agent infiltrates an opponent's custom-built headquarters, moving room by room through a maze of walls, deadly traps, vigilant guards, and security robots in search of valuable secrets. Every step costs precious Movement, Stealth, or Combat, forcing difficult decisions about how deep to push before your mission comes to an end. Meanwhile, another player is exploring the labyrinth you created. Because every lair is built by a different player, every game presents a brand-new puzzle to solve. The walls you place, the traps you hide, and the paths you leave open all shape your opponents' experience just as much as your own. Combining simultaneous play, spatial puzzle design, resource management, and tactical infiltration, Spyworld offers constant interaction with virtually no downtime. The mastermind who best balances offense and defense will walk away with the greatest fortune, and one step closer to world domination. description from the publisher
