To bring the laser to the Moon in Totally Safe Moon Project, build the tower high enough first, then carry the laser up it exactly like any other prop and set it up at the top. The laser waits for you in the garage on a marked platform with a yellow warning triangle and the label "Bring to the Moon", and firing it from your own tower is what destroys the asteroid and ends the run.
Totally Safe Moon Project How to Bring the Laser to the Moon: the delivery
- Get the tower high enough. The "NEXT GOAL" banner in the top-left and the moon-topped meter on the left tell you where you stand — the height goals guide lists the checkpoints.
- Take the laser off its platform. Walk into the garage to the platform marked with the yellow warning triangle. It is the one prop in the game that arrives with its own instruction on the floor.
- Carry it up your stack. The laser behaves like every other prop: grab it with the gravity gun, climb with it in your hands and hold on to the placement, because it has to be carried and set up on a stack that is already wobbling.
- Set it up at the top. Once it is standing on the finished structure you can fire it, with props still being carried up around it.

How to destroy the asteroid
The laser is the answer, and only the laser. The rock itself is visible from the ground long before you are anywhere near high enough to hit it: it hangs over the town as a glowing red-pink mass, and during meteor showers streaks of light cross the sky around it.
Firing the laser at it from the top of the tower destroys it, and the achievement "National Heroes" — "Finish the game by destroying the asteroid" — is the completion condition for the whole run.
What happens on the way up
The delivery is the same climb as any other, and it inherits the same interruptions:
- Meteor showers can take out a third of the tower, laser included, in a single event.
- UFOs hover over the streets and lift props and players with a green tractor beam, so an unattended laser can be carried off the stack.
Both are covered in the asteroid rain guide and the UFO guide.
Is there another goal after the asteroid?
No. Destroying the asteroid is the only completion condition in the game, and "National Heroes" is the only achievement that ends a run. Players who reached the Moon have asked whether there is anything worth climbing past 800 metres, and nobody has answered yet: the height ladder keeps climbing past the last named goal without a stated purpose, so the laser and the asteroid are the closing act of a run rather than the start of a second one.
