Not online, yet. I believe they are working on it. However, you can create levels with your friend who is playing with you on the same PS3.
Its in costumes bag if not finish first lvl and second.
the last one "The Collector" not to bo confused with "Collectors lair" that is my opinion. the hardest level is "The Bunker" in the wilderness theme
Ok first off let me say that this is totally wrong but kinda cool... All you do i go on the community and find a glitch lvl and it will tell u all that stuff.
create a new account and stay lvl 3
I beat it with Staraptor lvl.57 uxie lvl.53 and palkia lvl. 56with torterra lvl.47 geodudelvl.8 and another weak pokemon(i forgot which one.
There are 3 ways...just 3... 1) catch a wailmer then evolve it at lvl 40 (simplest method) 2) catch a wailord (harder but you never know what you might get, I got one at lvl 32) 3) trade with another person
First you will battle:Will- Xatu lvl. 40, Jynx lvl. 41, Exegutor lvl. 41, Slowbro lvl. 41, another Xatu lvl. 42.Koga- Ariados lvl. 40, Venomoth lvl. 41, Forretress lvl. 43, Muk lvl. 42, Crobat lvl. 44.Bruno- Hitmontop lvl. 42, Hitmonlee lvl. 42, Hitmonchan lvl. 42, Onix lvl. 43, Machamp lvl. 46.Karen- Umbreon lvl. 42, Vileplumpe lvl. 42, Gengar lvl. 45, Murkrow lvl. 45, Houndoom lvl. 47Champion Lance- Gyardos lvl. 44, 2 Dragonites lvls. 49, Aerodactyl lvl. 48, Charizard lvl. 48, Dragonite lvl. 50.
You can get the intervention once you can create classes at lvl 4
you can go down to create a class after u went into multiplayer or splitscreen and you have to be lvl 4
you get it by either getting lvl 30 then doing vettel challange in a-spec or get to lvl 35 in b-spec. another alternative is buying it at lvl 35 a-spec for 20million credits
u must buy the metal gear sollid lvl and beat the first 2 lvls of it.If u also want to know how u get water then u get the pairate of the cairbaian kit for water.
You have to be level 80 in order to join or create an arena team.
