Robo Defense FREE is a tower defender that stands out for its quick and addictive gameplay. It's one of the most basic tower-defense games on Android, but that may make it one of the best. You have to pay up to unlock all of its levels and maps, but it's worth the $3.
This application comes as a toned-down version of the full game that only gives you 11 levels on one map. You'll unlock endless upgrades and gameplay with the premium version of the app. That's a refreshing change from the "freemium" tower defenders that go on forever but get annoying if you don't pay for upgrades. Robo Defense FREE is different from those apps thanks to its dead-basic layout, as well. There are no ads, animated opening sequences, or really anything getting between you and the core game. In fact, the game is ready to start right when you open the app. The gameplay moves just as quickly. There's no build time or recharge time needed to create your weapons. As long as you have the money, you can build it right away. There are various achievements spattered throughout the game, but they are tough to unlock. That's because the game's difficulty gets intense really quickly, which makes this app a delight for fans of old-school tower defenders.
If you're nostalgic for 8-bit defender games, Robo Defense FREE is the perfect game for you. It's easy and addictive enough that everyone will enjoy it.
