I love this game for so many reasons, it's hard to list them all. Sufficient it to say, it is because of Zombie Horde 3 that I became hooked on the zombie flash genre. It feels like an RPG, with your protagonist trying to escape the city, yet it also feels like a good shooter, with all the weapon upgrades. Plus, there is car, which is really pretty awesome, although it is hard to drive at times.
A truly revolutionary video game. Thank you to the creator so much for getting me started on this path of enjoying the flash game zombie genre. It's been a true gift to me.
