To get out of the cave you must defeat Piccolo and if you lose there is a healing pool back in the cave. On Kaiousama's planet you must beat the planets gravity within the use of 15 Battle Cards. After you finish this, you will then fight Kaiousama. If you beat him you will get called back to Earth by Shenlong. The house next to Kaiousama will refill your Hit points and KI between failed training attempts.
On Earth using Piccolo and Gohan, look around to find Yamucha,Tenshinhan and Chaozu who will join your party. Also if you were very quick in Gokuu's training he will join you now or later on. When you feel your characters are strong enough or the random battles stop seek out Nappa and Vegeta. Before you fight Nappa, you will have to battle 1 Saibaman and then a group of 5 Saibamen. After you defeat Nappa, he fires on last Ki blast that kills Piccolo. Gokuu leaves with Vegeta to fight him by himself. As Gohan you can follow Gokuu and Vegeta to join the fight. After you defeat Vegeta, you get the Vegeta item card.
After this all your remaining characters except Gokuu go to Namek. Once on Namek there will be many things for you to do. On the map, north(up) of where your ship landed,and to the east(right) a bit, Freezer, Dodoria and Zarbon are destroying a village. Go to the village and watch Dodoria torment some Nameks. When Dodoria is about to kill a Namek child, Gohan
comes in and rescues him. You then fly away with the child and attempt to escape from Dodoria as he fires Ki at you. You lose hit points for every hit taken, but the damage varies from character to character and depends on their HP. After escaping from Dodoria, you land in the center of a hill in the bottom right section of the map. The
child, called Dende, joins your party but can't fight in battle.
Find the destroyed Namek village (pictured left) around the center of the map. Go into the house where Gohan is pictured and search the pots that are inside. You will find Dende's brother Cargo hiding there. He will then join your party, but
do even less then Dende. Then find the Namek village that is not destroyed with the Dragon Radar if desired. There will be two Nameks standing out in the open in it.
They are Tsumuri and Maima, and if you have rescued Dende or found Cargo they won't fight but will join you and give you a Dragonball. Go to the cave at the bottom left hand side of the
map and enter (use your Dragon Radar if you are lost on the map). In it you will find in the capsules and holes in the walls, that either contain item cards of explode and
hurt you. There is a long passage in the cave, that is booby-trapped. As soon as you walk up the passage, a giant rock rolls down that damages you every time it
hits you. You need to time it right and stay to the right side of the passage to avoid the rock as it rolls by. At the end of the cave you will find a Dragonball.
After getting the Dragonball and exit the cave by going north. You are then forced to fight Kui. After doing all this Bulma will call you repeatedly
telling you to return to the ship (happens if you walk around). Once you get there, Dodoria destroys the ship with a Ki blast, and then you are forced to battle him. After defeating
Dodoria everyone leaves.
Then it switches over to Gokuu who is on a ship heading for Namek. You train him by trying to defeat the gravity made by the ships gravity generator. The gravity generator is on the second floor of the ship, and is the large machine in the center of the room. When you walk up to it, it will ask you if you'd like to train, you then decide by pressing up or down gravity level you want to train in (10 - 100). You fight the gravity then as you did on Kaiousama's planet. If you lose to the gravity it's game over, so run if you are going to lose! After defeating the gravity a few times, you then control Piccolo on Kaiousama's planet. The first thing you do is train by fighting the planets gravity like you did with Gokuu. After completing this, you must face both Nappa and Radittsu at the same time. After you defeat Nappa and Radittsu, you will get to see Vegeta and Zarbon battle on Namek.
The game then cuts to Nail talking to the elder Namek. Freezer comes, then Nail and him leave and fly off to fight. Freezer is to powerful to be beaten so don't bother trying. After Freezer defeats Nail, Nail lays on the ground critically injured. Then the game cuts to Dende talking with your party. Your party then fly to a small island to the north where they summon Porunga. After making some wishes the Dragonballs turn to stone and you leave to Namek map#2. Nail lies injured on the ground where he fought Freezer. You must now got to the elder Namek's house to fight Freezer. To get there Freezer has made a convenient hole in the cliffs for you to use. After the 1st round in the battle the game switches over to Piccolo who is now on Namek. Go to the injured Nail to fuse and raise Piccolo's Battle Power greatly Then the game returns to your battle with Freezer. After reducing Freezer's HP to a low level, he transforms to his 2nd form. During the battle against form 2 Freezer, Piccolo comes and joins the battle. Once you beat Freezer he disappears and you go to the valley that you fought the Ginyu Force in (Namek map#3).
After returning to Namek world map#3, seek out the Namek village that is in the cliffs in the upper right section of the map. At that village are Tsumuri and Maima. Talk to them, and they will give you a choice of either raising Piccolo's Battle Power and losing Dende or don't raise Piccolo's power and keep Dende (bottom choice is keep Dende). After you've made your decision go to the cliffs just south of the village where Freezer awaits. Freezer is guarded by 3 groups of his henchmen. After defeating all 3 groups of bad guys you take on Freezer who transforms again into his 3rd form. After a while Freezer will leave the battle, then you fly around until you find him. When you find him he will fight you for a few rounds, and then leave like before. You find him over and over until he takes you to an island at the bottom right of the map. He will then fight you instead of running and once weakened enough he will transform again to his last form. After a while the game cuts to Gokuu who is now healed. You can make Gokuu go to shops to buy items for the battle or make Gokuu go straight to the battle. Once Gokuu joins the battle, have someone weak like Chaozu fight Freezer alone to kill him off. On Gokuu's next turn Gokuu will get really mad and turn Super Saiya-jin (pictured left). Use a BP increasing card on Gokuu if you have one, and have only Gokuu attack because Gokuu is the only one who stands a chance. Once Freezer is beaten the credits roll. If Vegeta survived, you will then fight him but this time he is a Super Saiya-jin and stronger then Super Saiya-jin Gokuu! To have a chance of beating him without an "Eldest Namek" item card you'll need to be well stocked with healing item cards.
