There's a bug that causes the game to think you're a new player. Reload the space until your level and status is displayed properly.
Also, it may take a few reloads of Home to receive all the parts of the ninja costumes.
I've added some more titles. If anyone knows the number or unlock requirement for these, please respond.
You may now pickup spinning colored cubes during a match. These can be mixed to create items at the L-Project game in Peakvox Labs. A cube will spawn in a fixed position once per game. It's independent for each player, so everyone has an equal opportunity to pick it up. Once you've collected ten cubes, they will stop spawning.
The players who can enter the beginner's area with ranks that high are probably boosters who have atrocious k/d ratios. As LeeStone mentioned, a PvE area would help counter that effect. Some of these boosters have taken over lobbies and attempt to ruin the game for anyone trying to play it the right way.
