Go to Metallis. Near the ship there should be a door that you have to use the Polarizer on. There should be a warp pad beside it if you have went all the way through it. Make sure you get the first warp pad. Press the home button and go to the PSP main menu. Ghange the time on the system to 2:42:00 AM. Then load the game get on the warp pad and look around the arena for a different warp pad. It should say press triangle teleport to a secret arena. Press triangle and you are there. Have Fun!
This isn't a useful glitch but it is cool. First select the weapon you want to use. Then pull out the wrench. Jump in the air and glide. As soon as you glide let go and hit circle then square before you land. You should slam the gadget/gun on the ground and hear the firing noise. (if you use the "water gadget" it will continue to make the sound unless you change weapons.)
This glitch only works If you got the sludge mk9 suit armor. Okay go to ship wearing the sludge mk9 suit, when it says press Triangle to enter ship double jump then press Triangle. You should still be dropping sludge all over the ship and inside it too!!!
