Dragon Ball: Raging Blast

There is an easier way to get the achievement. There is an object that we'll ask the dragon makes a multiple of 1.25 we get more on the total amount. Once equipped with this object in our character, we get an average of 500 to 1000 more, enough to surpass the 3000 that we require.

This was super easy for me. Play as Super Sayian 2 Vegeta, and fight Chiaotzu. Chiaotzu has only two bars of health which mean you gets lots of bonus time. Use a charge attack and knock him away, and charge your energy to max and spam Final Flash. May take a couple tries. If you hit Final Flash about 20 times you should get the achievement!

For this one I used super gogeta against trunks.
-Super gogeta has 5 health bars = more hits before K.O.
-Trunks has 3 health bars = Less damage before bonus time.
I spammed the air move where you knock them in the air with up + Y and then A,X,X,X,X,X. Do not charge ultimate attacks just use special attacks as soon as you get them, as ultimate attacks take a while to charge. I did this first time using this method. Hope it helps.

This one i found a little hard, took me a few attempts but i did it with super vegeta, against vegeta. I didn't bother with the 5 point attacks like charge attacks or anything. Basically, i charged until i had final flash, and spammed it. Sometimes if your lucky, and the computers life has run out, you'll enter bonus time which will score you double points for a set time. And what i mean by lucky is, if you knock the cpu up with a high smash, then follow up with A, then X to do the mid air rush sending them back down, they tend to just spam beams back at you like Galick Gun, and with that being done, you can activate final flash and win the Beam battle mode where you rotate the left stick, winning this in bonus time nets you 400 point and can sometimes be done 3 or more times.

OK, so for this achievement, i picked the best match-up i possibly could that we more than unfair. i was super saiyan 3 goku, while going against videl. videl has some extremely annoying combos, alone with counters, super attacks, and her agility. so therefore, simply spam her as much as possible. know her down with a charged "down" "y" and then while shes down, immediately charge up your biggest attack. you should have enough time, then just get close to her(but not too close) because she can teleport, and blast her away. she should fall after that, then rinse, lather, and repeat.
