The game kicks off when you're recruited by Unlosing Ranger to take his mantle and complete his quest to vanquish Darkdeath Evilman and rescue the Super Baby. Well, "recruited" is probably too strong a word. It's more like the Ranger is hit by a car on the way to the battle and you just happen to be there at the time. You're given the powers and told to fight. Things don't go that well, but at the last minute, you're whisked away to Bizarro Earth and given a second chance.
Once on Bizarro Earth, a trainer who, after questioning your status as a hero, decides to toss you into a high-level dungeon for an intensive training session meets you. Lucky for you, the ghost of the original Ranger steps in and talks the trainer into a slower start.
From here, gameplay revolves primarily around venturing into dungeons and completing missions. Z.H.P: Unlosing Ranger VS. Darkdeath Evilman follows the basic mechanics of a roguelike, but with a SRPG twist. Everything is still turn-based, but all turns take place at once, removing unnecessary menus. It's an inventive way to handling movement and a lot of fun. Dungeons are randomly generated and you're almost always guaranteed to find some new weapon or part.
Playing through dungeons is the only way to get power. It's also one of the game's more confusing elements. Your character has two levels, one from inside the dungeon and an overall level. From what I can tell (and I admit I could totally be missing something here), there's little correlation between the two levels. Every time you enter a dungeon, you start at "Level 1," but it's a modified version that somehow relates to your overall level, which is much higher.
Not knowing how the leveling system works didn't hurt my fun, but I couldn't find the logic behind the concept either. Eventually, I just ignored levels entirely and made sure I had the right body parts.
When you get right down to it, gameplay is really just about making sure your health and energy levels stay up. Health is obvious, but energy is a unique wrinkle. Every action drains energy, and no energy means no actions. The game does a really good job of dangling carrots in front of you to make you waste energy. Great weapons are always off the beaten path and you're given the option to dual wield weapons. It looks crazy cool and the damage is nice, but it also drains your energy quicker than a normal attack.
There's just as much to do outside dungeons as there is inside them. In order to gain ultimate hero status, you'll need to outfit your base with gadgets. Every object you purchase will help you out on your quest. For instance, purchasing a blacksmith lets you repair weapons without exiting the dungeon.
