Welcome Alliance Decoder
We are so grateful that you have agreed to help us.
As you have heard, aliens have stolen our space ships.
They are attempting to escape in them.
We have not been able to stop them because we cannot
identify them from the ships controlled by our forces.
We know that you can help us identify the ships, and allow us to recapture them.
On your display panel, you will see clues from our central intelligence agency.
Help us identify the ships by clicking on them.
I know with you on the job we will be safe.
Thank you, and good luck.
