Not Now, Aliens!
TWEN
The aliens have given humanity 8 hours before Earth is destroyed. Use a Gravity Gun to lift anything in the city, build your own path to the giant UFO, and save the planet solo or in online co-op for up to 4 players.
Overview
The aliens have arrived and given humanity 8 hours before they wipe out Earth and claim it as their new home. Fortunately, they made one tiny mistake—they accidentally dropped an experimental Gravity Gun, the only weapon capable of stopping them.
BUILD YOUR PATH TO THE TOP
Use anything you can find to build your own path to the gigantic UFO. Pick up, rotate, and place everything from traffic cones to entire buildings.
UPGRADE YOUR GRAVITY GUN
Collect alien technology, upgrade your Gravity Gun, and unlock the ability to lift even bigger objects.
GET USEFUL AND FUN ITEMS
The higher you climb, the more respect you earn from the city's citizens. Trade it for useful tools, ridiculous gadges, and hilarious items that will help you reach new heights—or create even more chaos.
Play solo or team up with up to 4 players in online co-op. There are no predefined routes or right answers—just physics, creativity, and one question:
Can you reach the UFO before time runs out?
