Create, upgrade, and customize your very own Bloons Monkey City in this groundbreaking blend of city building and tower defense awesomeness! UNIQUE SIMULATION + STRATEGY GAMING Take back the wilderness from the invading bloon hordes and pop your way from a modest settlement to a thriving metropolis. Attack bloon-infested territory adjacent to your city, win a short tower defense game, and add the captured territory to your city as a space on which to build. Buildings are the heart of your city, and each one has a specific purpose - individual monkey towers for battle, upgrades for those towers, farms and banks to drive your economy, power to supercharge your city, epic buildings for epic powers, and decorations to make your city more awesome. Every time you build, your city looks cooler, you increase your power potential in tower defense play, and you open up even more rewards and challenges. AMAZING DEPTH AND VARIETY All 21 of the fully awesomized and carefully balanced Bloons TD 5 towers are available within Monkey City, with completely new unlock mechanics. More than 130 buildings and decorations give you endless strategies and city design options. Explore the wilderness to find treasure tiles and uncover 11 powerful special items like the Banana Replicator and the Dark Temple Idol. Burst bloons on 55 all new tower defense maps or test your mastery on 13 wildly challenging original special missions. Either way, be ready to encounter all new bloon waves and special bloon attack patterns like Cash Starve or Fast and Furious. REINFORCE YOUR FRIENDS Connect with Facebook and Game Center friends, then help each other win and expand. Send Supply Crates back and forth for bonus starting cash. Visit friends' cities to check out their strategies and their city design skills, and while you're there root out any bloon spies to win a reward for both you and your friend. SHOW OFF YOUR SKILLS Build up the strongest lineup of monkey towers possible and compete with other players for the best score in weekly Contested Territory events. Use the latest in monkey science to send player vs. player bloon attacks, then see whose defenses are the strongest and earn extra rewards for victory.

Welcome to Assembly Line 2, the sequel to the factory-building and managing game. Assembly Line 2 combines elements from idle and tycoon games. Make the most money by using different types of machines to build an assembly line to craft resources and sell them. Unlock upgrades to make it more efficient and expand your factory. The goal is simple, build resources and sell them. Starting with a few machines and very basic resources, and using them with more advanced machines to craft and create more complex resources. Your factory will continue generating money even when you are offline. When you return to the game you will have piles of money waiting for you, but don't spend it all in one place!
