One Heart-tank is hidden in each of the main eight stages. The heart increases the maximum HP of the character who collects it by two units.


Two sub-tanks are hidden in two of the eight main stages. Collect yellow DNA-souls and energy capsules to fill them up. Select a sub-tank from the menu to refill the character's energy.

  1. Flame Mammoth's stage (either X's Legs Upgrade or Zero's Leg Crush required)
  2. Wire sponge's stage


All the parts unlocked.

Parts can be acquired in exchange for DNA-souls, the "currency" in this video game. A part is unlocked when the characters collect a given number of DNA-souls. After beating any Maverick boss, including the intro stage boss, the characters gain 200 DNA-souls; smaller amounts of DNA-souls (4, 8 or 12) are randomly dropped by regular enemies.

In the table below, default sorting is by unlock value.
