What is Stack Chaos: Alien Express?
You pilot a goblin UFO that drops possessed objects with a pendulum tractor beam. Where it lands, it stays. You've got 5 seconds per delivery. Physics does the rest.
Over 400 cartoon horror objects dangling from a pendulum with real inertia. Every drop is a gamble: do you release early for more points or wait for the perfect moment?
11 Game Modes
- Normal — finite objects. Plan your tower with the mulligan or die trying. Beat it and you'll see the ending cinematic.
- Infinite — endless objects. Survive as long as you can.
- Time Attack — 2 minutes. Speed > precision. How much can you stack before the buzzer?
- Daily Challenge — same objects, same order for everyone. Daily leaderboard. One shot per day.
- Bombardment — constant meteorites hitting your tower while you stack. Survive.
- Inverted Pyramid — small ones first, big ones last. The base wobbles from the very first drop.
- Go Low — lowest tower wins. Compact, crush, fit.
- One Size — one random object, that's all you get the entire game. Master it or suffer.
- King of the Hill — challenge the #1 leaderboard ghost. Dethrone the king.
- Skyscraper — 50 fixed objects for everyone. Pure skill. Ranks from Bronze to Diamond.
- Bank Shot — use the birds as tools. Bounce, straighten, and build with calculated impacts.
