Alias is, at its core, a simplistic take on the stealth action genre. As you make your way through the game's levels, you can toggle on and off a specific stealth mode that allows Sydney to creep along at a slower, more methodical pace. You can also crouch to duck behind objects as well as press yourself up against a wall and peer around corners. When in stealth mode, you also have the option of performing stealth attacks on enemies. For instance, sneaking up behind an unwitting foe and pressing the stealth kill button performs a unique move, depending on the enemy and what kind of weapon you happen to be holding at the time. There isn't an especially wide variety of these moves, but they're cool nonetheless.
It's Cool Game That I'm recommending to everyone.
