In this Bomberman adventure, it seems that the Garaden Empire attacked the planet Primus Star. Princess Millian was kidnapped in the process, too. A weird robot, Pibot, escaped via spaceship—but it crashed. Bomberman was told to check out the crash, came across the robot, and thus, Pibot was able to tell him about the trouble. So now it's up to Bomberman to save the universe.
Control in Bomberman Hero consists of firsts and familiarity. Like usual, only the Control Stick can be used for movement. Press it a little to walk and a lot to run. The only problem is that it's too loose. The A button is for jumping—a Bomberman first. The B button throws bombs, and you can walk, run, and jump while throwing and aiming them. Holding down the B button enables a special "Rolling Bomb" attack. The R button or Bottom C button (you can use either one) lets you set a bomb in place. You can then kick it by pressing the button again or by running into it. The Z button explodes a remote control bomb. Finally, the Left, Right, and Top C buttons let you temporarily and slightly adjust the camera. You cannot move while controlling the camera, nor can you change it permanently. It's almost kind of useless, which can be frustrating.
There are also slightly different control schemes for your Power Gear toys—Bomber Marine, Bomber Copter, Bomber Slider, and Bomber Jet—and for Louie. In the case of the Power Gear toys, it's usually that the A button ascends, the B button hovers, and the R, Z, or Bottom C button is your attack. In the case of Louie, an animal you can ride on, you destroy things by jumping on them.
One of the nice things about Bomberman Hero is the vast number of levels. There are approximately five planets; each planet has three areas and a boss, and each of the areas has about four to seven levels inside! That means there are over 50 levels in the game. Also of note about the levels is that each one is relatively short, straightforward, and easy to complete. Furthermore, some levels have several exits. Fortunately, you can go back and play any level already completed.
In a nice change of pace from the "collect X number of these items, Y number of these, Z number of these..." type of gameplay seen in Super Mario 64, Banjo-Kazooie, et al., you basically only have to reach the exit. There are crystals to collect along the way (200 will increase your life meter by one; you start out with four pieces of the meter and can get up to eight), which net you points, and you can defeat enemies for more points. There is a target number of points to reach on each stage. If you defeat all enemies and find all items, you should have a perfect score, if not a few more points! But it's not necessary to do this unless you want to open up the secrets. Even then, it not as painstaking to collect and kill everything as in other 3D games.
There are quite a few items in the game. First of all, you can find some classic Bomberman power-ups. For example, the Bomb Up increases the number of bombs you have (up to four). Fire Up increases the blast radius of the bomb blasts (up to four). Then there are these other power-ups: Remote Control bombs (detonators), Life Hearts (fills energy by one), Full Hearts (fills all the way), 1-Ups (extra life), Salt Bombs (used to solely destroy slugs), Freeze Bombs (freeze enemies), Fire Resistance Suits (makes it so severe conditions, e.g., wind, will not damage you), Wall-Through items (lets you walk through walls), and Power Gloves (used to throw bombs farther).
There are many non-power-up items you'll encounter, too: Bubble Panels (makes Bomberman float), Transceivers (for hints), Crystals (collect to increase your life meter; blue is worth one crystal and 50 points, red is worth five crystals and 250 points), Gold Stones (worth 500 points), Rainbow Stones (worth 1,000 points), Key Crystals (collect four to open the exit on some levels), Card Keys (must be found on some levels to open doors), Other-Dimension Bombs (hidden on many levels; opens up a secret if all are collected), and Data Disks (needed to open certain doors).
