The Uppers are a set of maps that are known to have higher level players and many more PvP battles than in the Lowers. Most of the upper maps require a certain level to even enter, so beware of FE players regularly.
The only path to the upper maps is through the battle maps, which is a set of maps specifically for PvP battles since you cannot jump through a portal if under attack/firing on another ship. The alternate way to get to the uppers would be by purchasing the Advance Jump CPU which does cost Uridium, or can be found in the Auction.
X-5 is the map mostly used for traversing and boxing. Level 10 is required to access this map.
This is the first upper map you enter after traveling from 4-4. Many aliens are found on this map which should be easy to handle except in swarms. Boxes and resources are found on this map.
