ZOMBIE SLAP! Forget everything you know about surviving an apocalypse. You don’t need to scavenge for shotguns or barricade doors. All you need is the legendary power of a perfectly timed, screen-shaking Ottoman Slap. The undead are crashing your peaceful dojo, and they are literally walking right into your hand. It’s an endless, hyper-addictive survival arcade where your only job is to swipe, slap, and kick until your reflexes (and fingers) give out. But don't get too comfortable. Things get incredibly chaotic, real fast: BALLOONS = PURE CHAOS See a floating balloon? Swipe it! It might turn your bare hand into a devastating Fire Slap, trigger a slow-motion matrix moment to let you breathe, or literally drop a giant bomb to clear the entire bridge. THEY BROUGHT HELMETS?! Yeah, these aren't just your typical brainless walkers. The longer you survive, the more paranoid they get. Soon, they'll start showing up wearing hardened helmets and full body armor. You'll need lightning-fast double-swipes to crack their defenses before they get too close. PLEASE DON’T SLAP THE LOCALS Every now and then, a totally terrified (and uninfected!) civilian will run past you, screaming for their life. DO. NOT. SLAP. THEM. Giving an innocent human an atomic high-five will cost you a precious life. Keep your eyes peeled! WHY YOU WON'T BE ABLE TO PUT IT DOWN: • Super smooth "swipe-to-slap" controls that anyone can learn in 3 seconds. • Crazy satisfying haptic feedback—you'll physically feel every clean smash. • A difficulty curve that goes from "Ah, this is relaxing" to "OH MY GOD MY FINGERS" in minutes. • Global Leaderboards so you can historically dunk on your friends' high scores. Warm up your swiping finger. The apocalypse is here, and it desperately needs a good slap!
