Virtua Fighter 5

just complete the arcade mode with all characters.

If you are finding this hard just go into the options menu and turn the difficulty to easy,put your life bar to the biggest and put the cpu life bar to the smallest.

If you die you can press continue as many times as you want

you do not have to beat dual (bonus stage ) to get the achievement

To earn the achievement "Dural", you must play and conquer the Arcade mode

This is what I did to earn the achievement.

-Start up the game and go to the menu.
-When you arrive at the menu, go to the options menu.
-There are two lists on the next screen. The top one is Arcade, which is the one we should be worried about. I recommend putting it on Very Easy for the difficulty, set the rounds to one, raise YOUR lifebar at the highest possible, while lowering the ENEMY AI's lifebar at the lowest. So it should be 300 for you and 160 for your opponents.
-Once that's done, go ahead and back out.
-Start Arcade mode, chose a character, then do what you have to do.

You will need to go through the Arcade mode with all twenty original characters. It's not really difficult at all, you just need to know a few quick, fast combos to get the job done for all of your foes. Dural DOES NOT need to be defeated. Either you beat her or you don't, the achievement will unlock once you complete it with the last fighter. For me, it took me last than two hours to complete it because I already finished it with three others, then finished up with the rest of the cast. My last character was Vanessa Lewis and she earns the MVP for earning me the achievement! :D

After you win or lose to Dural with the last fighter on the roster and reach the screen where it calculates your scores and rank, the achievement should unlock. As an added bonus, you also unlock Dural as a playable character, so you will get to kill two birds with one stone.

As long as you follow the instructions I listed above, you should be OK. If you just started playing the game, then yes, it will take you two hours, if not a little more, to earn the achievement. However, if you've beaten it with some characters, the time for earning this achievement should be less than it was before!

Have fun and good luck!

I got the achievement using the tips from above. Some info are missing and I am summarising all of them below:

Go to menu -> Option -> Arcade, Change the following settings
- Difficulty: Very Easy
- Round: 1
- Raise your life bar to max (300) and your opponent to minimum (160)

When you start up the arcade mode, select "Play with no data", then just play with each character. During the match, I spammed to easily defeat most opponents. If you die you can press continue as many times as you want.

You DO NOT need to beat dual (bonus stage) to get the achievement.

The fastest way to get this one is to put the diffuculty on " very easy" ; number of round : 1 ; time : 15 sec.

You have to do it for the arcade mode in the options menu.
By doing that, it can be done in les than 2 hours.

Good luck !!!
