Dragon Ball Z Budokai HD Collection

You'll need to have 32 or more characters unlocked and have beaten Adept World Tournament. Then purchase Advance for 6,000 Zenie from the Skill Shop.

Just like Budokai 1, the best way for you to win will be using the heart disease method consisting of the Senzu Bean, Heart Disease and the Vaccine which will bring down your opponent to half way health on the last bar. Unlike the first, you will have to manually activate Vaccine by holding and pressing twice. You then have two ways you can go about winning the match: first you can play it safe and wait for your opponent to be weakened and then go in for the kil,l or secondly you can always go for the faster way and ring out you enemy but be warned as it carries a risk as they can dodge you and knock you out instead. In case you do die, Senzu Bean will revive you at full health for a 2nd attempt but will not work if you get ringed out.

Another strategy that you can do is have Goku equipped with SSJ4 + Kamehameha along with chilled juice, basically you will back away from your opponent at the start and use chilled juice and then transform into SSJ4 and spam Kamehameha. You can always use your own custom items set to win or play it fair and square and win with sheer skill if you're confident.

Note: For Vaccine, you can find it in Vegeta's playthrough in the Android Saga by visiting Goku's House. For Heart Disease, you can find it in Goku's playthrough or as a random item in the field. Also you can find both of them in shop for 6,000 Zenie but they are rare and will take some time.
