perfect_dark- If you still have blanks you probably haven't unlocked all the weapons yet. If you go through multiplayer quickly you shoudl be ble to unlock them easily using the Challenges.

Ps2owner- The Skedar leader is quite simple to defeat. I'll give you a hint, he is invincible but look around where he is and you should see something change when he ducks down after you shoot him enough.
