CooLoserTech included Range of the Dead @2:04 in his Best New Games of the Week video; cheers! It's free!
Saga of the Dead is a zombie series of games that started with Road of the Dead. Each game has its own unique gameplay and interesting story but they are all part of the same universe. There are four main characters; John Creasman (RotD), Allen Creasman (LotD & RotD) & Diane & Cocheta (RotD2). Range of the Dead 2 & Streets of the Dead are also planned.
