I apologize if this answer is not exactly what you asked for, but this is the best I can do with your asked question.
In the KillZone 3 campaign you will automatically be given Sev's haircut. If you are playing the multiplayer campaign you will need to be player one (1). Player one controls Sev, and player two (2) controls Natko.
I do not believe that you will be able to have Sev's haircut online. It may be possible, but I have not seen it, as of this post.
Either way, with or without Sev's hair, the game is awesome. Please consider buying it.
Killzone 1 is, Killzone 2 is not and Killzone 3 is.
You can play the public beta for Killzone 3 on the 3rd of February, 2011.
Yes just like Killzone 2 was
The Killzone series takes place in the distant future. To be exact Killzone 3 takes place just minutes after the ending of Killzone 2, which is November 2359 to May 2360.
killzone 3 is exclusive to playstation so it won't be avilible on any other console
no but killzone 3 will have campaign co-op
I still play KillZone. KillZone 3 to be exact. Shooting angry alien people is still in fashion.
i havent played killzone 3, but i can tell you, cod modern warfare is a great game.
Killzone 3 is a PS3 video game released February 22 2011 and not playable in PS2
No.
No, Killzone 3 can be played using the PS Move motion controller, but it also has full support for DualShock 3 and Sixaxis controllers.
It is impossible to save your teammates in KillZone 1. But in KillZone 2 and KillZone 3 you are able to save a teammate by pressing a certain button, this button depends on your controller scheme. You will then pull out a "Heal Ray" and fire it at your downed ally. Thus, reviving them from the brink of death. In an online KillZone 3 game the "Heal Ray" is only available to the Field Medic unit.
