This game is considerably hard, due to your small health bar and the imminence strength of the bosses (however, power-ups and health tanks are still fairly common item drops.) The game spans eight levels including an intro stage and a final boss rush. There's no real ending to the game; after the last boss in the boss rush level is defeated the game immediately cuts to the credits. Several enemies are taken from Mega Man X / Rockman X and Mega Man 8 / Rockman 8, with the bosses being either recycled from previous Zook Hero games or being edits from other official Mega Man / Rockman Games. The main character's design is based off of X.

- The bosses, enemies and the floor of some stages are mostly taken on Mega Man X / Rockman X, Mega Man 8 / Rockman 8, various other Rockman games, and even bosses from previous Zook Hero games (the Mechanical T-Rex sub-boss and Abandoned Armored Robot boss show up in the game.)
- The Zero-like character who appears in the title screen and the credits, is called Midoll (米多爾), or Meduoer in the English version, and only appears in-game as the boss of the intro stage.
- A good chunk of the music used in the game are remixes of songs found in Super Fighter 2001 Alpha although there are new original compositions made for the game.
- Despite being called a Battle Network Mega Man game, it takes inspiration from the X series.
- The English release seems to have slightly different instrumentation for its music than the Chinese release's.
- Although it's never used the game features a V.Fame logo hidden away within the ROM's tile graphics, confirming Vast Fame had at least partial involvement with the development of this game.
