There are a total of 12 SECRET MISSIONS. In case you miss any you can carry all your progress over to hard mode. Once you beat hard mode you can select normal mode again and finish anything else you havent done.
SM1- Mission 3 Critical Hit - After you beat the spider/scorpion boss go back outside to the bridge and jump in the water. Aim for its weak point and defeat it with one single shot. Aim for the head! You can use the shotgun or pistols.
SM2- Mission 4 Phantom Baby - Defeat 100 Phantom Babies within the time limit. To start this secret mission click B on the wall at the start. Shoot with your pistols really fast. This is a pretty easy secret mission.
SM3- Mission 4 Defeat 100 Phantom Babies within the time limit without using any weapons. Go to the end of the hall as the giant spider chases you. Go into the door on the right. Secret mission will start. Turn devil trigger on and run over all the spiders. Use taunt before you leave to get your devil trigger back.
SM4- Mission 4 The Three Beasts - Fight the Shadow. You only have one chance. Kill all three beasts. To find this mission go back to the airplane room. Holy water if you wanna go easy/cheap.
SM5- Mission 7 One-Eyed Evil - Lure the Kyklops into their mutual death. You start this mission by clicking B on the door that leads to where you got the key in the previous mission. What I did is got into a corner and just kept jumping and jumping as one spider shot boulders at the other. Eventually one will kill the other. Once dead you dont have to kill the remaining one just head back to the door to collect your blue orb.
SM6- Mission 11 Wandering Ghosts - Acquire the Blue Orb that's floating in the air. To start this secret mission go through the door behind you when mission 11 starts. Just keep jumping on top of each enemy until you reach the blue orb in the air. Not too hard.
SM7- Mission 14 Eliminate all the enemies and escape. To start this mission when mission 13 ends and you technically haven't start 14 you can go back into the ship. Go back to the vent that leads to the captain. Click B on the captions body. During this mission you use the needle gun to kill all 8 enemies. Simple enough. Once all dead you will receive the blue orb.
SM8- Mission 15 Treasure of the Reaper - Defeat all the enemies. After starting Mission 15 return to the narrow corridor where
spikes shot out of the floor. Click B on the painting. Just kill the first shadow as fast as you can and avoid the spikes. 2 more will come eventually. Defeat them all and the blue orb is yours.
SM9- Mission 16 Stairway of Tranquility - Acquire the Blue Orb at the end of the stairway of death. Go back to the coliseum at the start of Mission 16. Just keep jumping to reach the top to acquire the blue orb. This can be frustrating but you will get it eventually.
SM10- Mission 16 Shadow of Darkness - Hunt down all of the Shadows. After Nightmare in Mission 16 go to the airplane hangar to start this mission. Find all four shadows and beat them. 2 are on the plane. One is hiding in the main entrance hall. The last one is in the caged area.
SM11- Mission 17 Blue Gem in the Sky - Acquire the Blue Orb that's located high in the sky. In the beginning of Mission 17 go back to the path of trials and jump across the bridge without falling into the water to start this mission. You dont need to defeat the Death enemy. Use his whirlwind spells to acquire the orb.
SM12- Mission 21 Hidden Bangle - You find this mission by clicking B on the wall opposite of the time statue. (who would of ever known to do that!?) You will find a blue orb early on but keep going to the big room jump up and kill the dragon. Once dead keep climbing to collect the bangle. Find the hidden bangle that resides in the secret corridor.
