A physics-based arcade game where you pilot a UFO dropping possessed horror objects to build impossible towers. Swing the pendulum, time the drop, pray it doesn't collapse. 400+ objects, 11 game modes, and a sarcastic goblin that roasts your every move.
Stack Chaos: Alien Express
SteamYou're an alien delivery driver with a tractor beam, a swinging pendulum, and exactly 5 seconds per package. Where it lands, it stays. Build the tallest tower of possessed cartoon horror objects... or watch it all come crashing down. We drop, you pray.
Your UFO swings cargo like a pendulum. Move left, move right — the package follows with momentum and inertia. Cut the beam at the perfect moment, or the auto-drop kicks in after 5 seconds. Drop fast = more points. Drop risky = even more points. Drop wrong = total chaos.
