Engineers! Here's my design for the new Colossus.
I've ripped it into 5 parts to make it easier.
Use each sketch to build a part of the machine, then we'll get Colossus working.
You'll need to hurry - many lives depend upon it.
Good luck!

You've cracked it!
You've built Colossus.
Because of you, enemy messages can now be decoded much faster and will bring a faster end to the war.
Well done!
