You Are Undead

You Are Undead is a stealth game in which you play a lone zombie in pursuit for brains in a post-apocalyptic street. Each level features a number of civilians you need to catch before the time limit is reached. Not all humans you find are helpless, since many of them are armed and dangerous. This is why you need to sneak up to them while they are looking or walking away from you. You can also hide inside buildings to avoid them. After you beat each level, you can choose a zombie (each with specific powers) to control in the next level, depending on how well you did.
