A wave based FPS where you defend a barricaded house against increasing hordes of the dead.
The game challenges you to defend a barricaded house against relentless waves of the undead. Each wave introduces new enemy types, from shambling zombies to spitting zombies and charging zombie bulls, keeping the combat fresh and forcing you to adapt your tactics. Between waves, you can choose to unlock new weapons or upgrade your character's abilities, gradually expanding your arsenal and strengthening your defenses.
One of the core gameplay loops is the weapon progression system. After each wave, you receive a new weapon, ranging from melee baseball bats to powerful firearms like revolvers, shotguns, and the devastating M16 assault rifle. Reviewers praised the satisfying feel of this weapon progression, noting how the later firearms excel at efficiently mowing down hordes of enemies.
Surviving the onslaught requires carefully managing your ammunition and positioning. The barricaded house provides initial protection, but its defenses cannot be repaired, forcing you to eventually venture outside and engage the zombies in the open. This risk-reward dynamic, where fighting from the house is safer but more limited, while fighting outside grants greater freedom but exposes you to greater danger, is a key part of the gameplay.
In addition to the campaign's 10 waves, the game offers endless modes that challenge you to see how long you can survive against increasingly difficult hordes. Combined with the random progression of weapon and ability unlocks, this provides a solid amount of replayability for those seeking to further hone their zombie-slaying skills.
