The zombie apocalypse is finally here... again. At least they are taking a tongue in cheek attitude to making a game that is very, very similar in almost every way to a 1,000 games just like it.
Yet Another Zombie Defense HD is a top-down arcade zombie shooter with tactical and strategic elements. During the day, you'll build up your barricades, buy guns and ammo, set up turrets, and struggle to stay alive. When night falls, the zombie forces become stronger and stronger with each wave, and your death is imminent. Get gunning.
Unsurprisingly, Another Zombie Defense HD is all about defending yourself against the ravenous hordes that rise to attack you every single night. The undead horde is overwhelming the landscape and sooner or later, your face is going to get chewed to pieces. It's inevitable, but the point isn't avoiding death, it's trying to stay alive as long as you can.
