Yes, you can. At the main menu, select Campaign at the very top, from there, there will be 3 choices: Continue Campaign, Select Chapter, and New Campaign. Choose the second option, and any previously played chapters (regardless if you start a new campaign or not) will be accessible in any difficulty, I believe.
no but killzone 3 will have campaign co-op
no
Absolutely not! The entire Killzone series is exclusively for the PlayStation 3. It is a first-party game and therefore will never be released on another companies console (I.e Xbox 360 and Wii).
You can't crawl in killzone but you can crouch though.
Killzone isn't out on the Xbox 360 so I doubt it will come out on the PC.
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.
