This map is based on the movie Aliens and is made to play on minecraft.
Even though it’s based on Aliens the movie, it’s an arena map not adventure map. Which means you battle against Aliens on levels of arena

There are few levels in the map started from your shuttle and then your squadron shuttles and the aliens levels below it.
In any case you just need to fight to survive / win.
