Build a Base and Steal: Pet Expansion Update Start Time and Countdown
Build a Base and Steal’s next scheduled event, the Pet Expansion Update, lands on Saturday, October 24 at 3:00 PM ET (12:00 PM PT; 8:00 PM BST). The developer has billed it as a pet-focused drop — pet nicknames, pet abilities, and a few additions that aren’t pets at all — and registered interest is already the strongest on the schedule, at about 24,000 and climbing. A week later, on October 31, the game follows with Rebirth 19 paired with another AA session.
The base-builder from replayable fun games is holding about 1,900 players in-game as of this writing, and across its lifetime the experience has drawn more than about 97,000,000 visits and sits at around about 390,000 favorites. The loop is simple: roll for rare pets, build a base to protect them, then use gear to break into rival bases and steal their pets while defending your own.
The schedule below covers what’s coming up and what just wrapped. Last updated October 24; we update this page as the developer’s schedule changes.
