The Arena of Oorama is a Maxis-made adventure, set in a large arena with very dangerous opponents on planet Oorama. You have to defeat 5 waves of enemies in order to complete the mission. For the entire adventure, there will be pillars in the arena with a Toksik and a power-up on each of them. Toksiks will stay on the pillars and spit at you. However, they will not respawn after they are killed, so it is recommended that you kill then at the beginning of the adventure, so that you can use the power-ups later on as necessary.
Round 1: In Round one, you must battle the Osgalts, Hellhounds from the Tartarus System, and their Trainers, the Beastmasters. The fight against the Hellhounds and their trainers is fairly easy, although that they may charge you with several dogs at once. There are four Osgalts and two Beastmasters. They both have rather low health.
Round 2: During this round, you have to defeat the Skex and Thorns, predators from the desert. These creatures have level 5 spit, but have relatively low health. You must kill four of each to pass the round.
Round 3: During this round, you must fight armed mercenaries. The Bronks are mercenaries with over 70 health and Bladed Knuckles, and the Blasters have only about 20 health and use Plasma Pulsers. You must kill four of each to pass the round.
Round 4: A swarm of Tuuks, small creatures with large jaws, covers the floor of the arena. They are very easy to kill, since they only have 5 health, but their bite is at level 5. An effective strategy is to herd a large group together, then kill them all at once with a missile or energy slash. The Tuuks will respawn, and you need to kill 15 to progress to the next round.
Round 5: The final round. An epic Grankor from the swamps of planet Mildor appears in the arena. It has over 200 health and powerful attacks. The Tuuks will still be there in this round.
Like in nearly all Maxis adventures, there is a hidden Spoffit in this one. It is located outside of the arena on a bridge, with a little house close to it.
