This game is similar and created by the same company as Adventure Quest, and dragon fable. The class called ghost catching is required Lv10 or up, deluxe pizza mecha, Silver Crossbow (from police place), sling missile (back shoulder), N-00B missile (front shoulder), wolf head, and standard Ghost trap.
You should know that deluxe pizza mecha cost 100,000 credits so it is hard to get it. And you need to unlock the rank first which means you also needed rank 20 in mecharoni, and at least rank 12 at police quest. Actually level 35 in energy blade class will be useful in the future so you might want to train some of these classes.
When you first joined the only thing you have to do is catch ghost until rank 20 then, which rank 0-1 will required 1 ghost, rank 2-3 will required 2 ghost, rank 4-5 will required 3 ghost, rank 6-7 will required 4 ghost, rank 8-9 will required 5 ghost, rank 10-11 will required 6 ghost, rank 12-13 will required 7 ghost, rank 14-15 will required 8 ghost, rank 16-17 will required 9 ghost, rank 18-19 will required 10 ghost, unlock a Mysterious mission. There will be a ghost hack into a space ship and tried to crash the whole city. So you and your mecha will need to defeat those ghost when you're done you have a rank of 21.
Then the next mission is the boss fight ghost mecha defeat it to unlock the fighting to the mysterious club. First a monkey, in the container; next punchy, the blue thing, keep punching it until it fight; then whoopee, a fart bag on the right. Those fights were fighting using your energy blade skill. The more skill you have the more powerful weapon it'll unlock. Then you can join the club now.
It only a short trick to get there and doesn't much useful but I hope someone who really doesn't understand in the past get what it is now. Have fun!
