Ok so these are some tips i have found to solo level 204 ( retake ) Faster.
THINGS YOU WILL NEED
A merc in the first slot.
Rush II, Charge II.
Elektra ++ set.
Obviously be lvl 200.
TA flags and minibot
Trans gauge Shoulder and shield.
Gun your choice.
A good trans that can do v,v,v,x,v,v,v,x combo really fast ( SuperKhanZ, Dark Knight, Lady Valor )
Then follow these steps to achieve greatness!
1st. Buy your favorite merc and put it in slot 1.
2nd. Make the room and start up lvl 204
3rd. When the game starts Jump down towards the scalper and drop your merc in-front of it.
4th. After you have done step 3 run up and start using Charge II
5th. When you trans if the Scalper isn't dead try and kill it, Same goes for Grade Z. Then go for the nimbas on each side.
6th. After step 5 go in the middle ( green grass square patch ) run to the left and right really fast like <- -> <- -> Until they get near you and then jump back and start v,v,v,x,v,v,v,x,v,v,v,x,v,v,v,xing them till there dead.
7th. Repeat that for the next Set of monsters
8th. Repeat step 6 for the next set of monsters. Try to get the bombs on this level to take out the mobs.
9th. You should be at the boss. The boss should spawn in the middle top of the grass patch. Then v,v,v,x,v,v,v,x,v,v,v,x him to the top till hes dead.
10th. Take a screen shot of your time and post it here.
