It says that you have to maneuver the Enterprise to the Alien token in short range like boarders.
This got us into a discussion if we needed shields down or not, and then why would we need the Enterprise to get shot at first, lose a shield and turn to let the alien board. Wouldn't the crew just take down shields? I Googled it, and didn't find a clear answer, so we just assumed the crew was smart enough allow it on board safely. - /u/G8kpr
