The game is designed in a way that's easy to learn, but difficult to master. Sneak Ops makes good use of the touch screen by dividing the screen into a grid, and you move your character simply by tapping anywhere on it. A blue trajectory line is shown at all times, which helps you avoid stepping where you shouldn't.
Infiltrating the base is no easy task, as all the guards and security cameras are alert, ready to catch you red-handed. Luckily, your visibility cone is shown at all times, and you can momentarily incapacitate the guards and run past them unnoticed. But the game becomes more complex each time you clear a screen, and you'll soon enounter invincible guards and areas of the map that make noise when stepped on.
Sneak Ops is an excellent stealth game, reminiscent of classics such as Metal Gear. On top of all that, there's items to collect along the way that can help or even save your adventure, and the base changes daily, so you'll never get bored.
