Navigate a grim, post-apocalyptic cityscape overrun by hordes of the undead, where human survivors valiantly battle for survival against frightening zombies. This slot features a 5x4 grid with 100 fixed paylines, immersing players in a dark and suspenseful world. The Vault symbol functions as a stacked Wild, substituting for other symbols to create winning lines. Landing three or more Biohazard Scatters activates the Free Games feature, where special multiplying Wilds appear, applying up to 3x multipliers to wins, intensifying the fight for survival and substantial rewards.
