You can find the APK on some third-party sites, but it’s sketch af. Use a VPN or something, don’t get clapped by malware. It’s not on the Play Store anymore so you gotta dig for it. Make sure you download the right version tho.
A lot of those links are straight cap, be careful. Look for something with solid reviews.
It’s kinda hit or miss on performance too. Doesn’t run great on every device.
Zombies mode on mobile actually kinda slaps when it works. Lowkey wish they’d bring it back officially.
