Here is a practice map you can load via Multiplayer or LAN.
Just add the folder to your MultiMissions folder.
I know its not the real QM its for practice purposes only.
I give you some information you can confirm and the numbers to start calculating the solution.
Play on any realism, takes seconds to load and its a good way to practice.
Enjoy ;]
