Biohazard: The Mercenaries 3D

Note: This cannot be done online. Have no Green Herbs in your inventory. Find a Green Herb and press Y + A to pick it up while using it. If timed correctly, the game will now show you as having 300 Green Herbs.

Try these costumes for a change! Have fun!

Clear Mission 4-5 with a B rank.

If you want to use a character's loadout so every other character can use it, score rank A or higher on all missions up to 5-5 with that character.

To make a particular character's weapons accessible to every other characters, score S rank using the character on every Missions up to Mission 5-5. Alternatively, you can spend 10 Nintendo 3DS Play Coins to unlock the character's weapons.

Complete mission 5-5 with at "B" or better rank. The EX missions will be available after the credits end.

Make sure that you have zero green herbs in your inventory. Locate a green herb and pick it up while using it (on the default control scheme, press the Y and A buttons simultaneously). If your timing was correct, the game will have tried to subtract one herb from a total of zero. This will cause the inventory counter to cyclically roll backwards to its maximum amount, resulting in 300 green herbs available for use. Note that this method will not work online.
