Yes, that’s right folks! High Voltage Software is honoring the brave soldiers fighting against the apocalypse this Memorial Day weekend with a price reduction to just $0.99 on their hit game Zoombies: Animales de la Muerte!. The castle-defense-genre game has been very popular for its action-heavy undead fun and novel gameplay style, which lets users trace the path of their weapon of choice, including Aztec hatchets, guacamole and even pinatas.

Since the Mexican zombie apocalypse began on iOS earlier this month, players have put over 18.6 million Zoombies out of their misery and cured as many as 150,000 additional undead. While the numbers speak for themselves, developer Eric Nofsinger is sounding the trumpet for brave new soldiers to enlist against the terrifying Zoombie hordes.

“Over 350,000 animales have been liberated from the affected zoo, and our zookeeper Don Eduardo is muy contento about that,” says Nofsinger. “But we’ve made the strategic decision to put the app on sale this Memorial Day to recruit additional anti-Zoombie warriors to the front lines.”

The game provides nonstop zombie action through 45 levels and 225 challenging Sugar Skull Missions that require timing, strategy and precision. Players have the option to battle as either Marco or Maria, two deceptively deadly students who pack a mortal punch, while trying to rescue as many animals as possible before their brains are eaten by the Zoombies. Adding to the fun, golden pesos can be exchanged for special upgrades, weapons, and costumes. Interested? You can download the game for $0.99 by clicking here.
