Grow an Army ️

Grow an Army is a military-themed idle tycoon on Roblox developed by 0 Thought Games - the same group behind Grow a City - where players purchase Army Units from the Army Shop, place them on a private plot, and earn passive Cash from their military force even while offline. Released in June 2025 and last updated February 2026, it has accumulated 7.7 million visits and 18.6K favorites with a 95.1% approval rating from 38K+ votes. Servers cap at 5 players.

Army Units replace buildings as the core income item, with tanks, soldiers, artillery, and vehicle-class units like the Humvi generating passive Cash just by existing on your plot. The competitive framing pushes players toward the largest army they can field:

• 💼 Purchase Army Units from the Army Shop and place them on your plot
• 💼 Units generate Cash passively - including while you are completely offline
• 💰 Reinvest accumulated earnings into more units and rarer military assets
• 🏆 Build the BIGGEST ARMY on the server and grow your military empire

Cash is the sole resource. The perimeter of your base can be upgraded with decorative fence gamepasses - Sand Fence (5 Robux), Concrete Fence (10 Robux), and Tall Fence (15 Robux) - at some of the lowest gamepass prices on Roblox. The x2 Luck pass improves random reward quality when earning bonus items. Plot expansion options are not included, keeping the base size consistent across players.

Grow an Army shares its template directly with Grow a City: same offline Cash mechanic, same 5-player server cap, and same developer. Both games were released within weeks of each other in mid-2025 as part of the 0 Thought Games "Grow a X" portfolio.
