To fire it press the shoot button and move it with the move controls (not aim)
The predator missile is not included in MW3 for Wii.
You can't, but you can protect yourself by having a trophy system around, or being inside a building.
Because in C.O.D MW3 all of your kills count towards kill streak rewards. For example if after you killed the right amount of people to unlock the pred missile you can unlock the next award in your kill streak set with kills gained from using the Predator missile. Hope I helped.
You need to achieve 25 (24 with hardline) gun-only kills in a row. In MW2, Your Assault killstreaks such as the Predator Missile and the AC130 counted towards the 25 kills, however in MW3, you need to get every kill with your gun/grenade/knife.
Assault Killstreaks such as the Predator Missile will count towards your Reaper or AC130. Also, the Lethal Support Killstreaks will also work.
same as black ops
They are those things that shoot things down.
It means, that you have killed an enemy, who was 1 kill off from killstreak. (example if enemy has 4 kills but needs 5 kills for predator missile and you kill him, so he wont get the 5 kill reward.)
No it is not possible. Games do not have passwords, it's the system that has the Parental controls like the PS3 or Xbox 360. How can you have controls on a Disc that can not be changed. Only the information loaded into the Platform can change. That's where Parental controls are and they would stop you from playing a mature game like MW3 or any Mature rated game if they were set for that.
You don't use tomahawks in mw3. Click Lb or rb whatever your controls are aim and let go lol
RS (right control stick)
They are the same in MW as in all the CODs, click the left stick
