Will the SCAR have a semi auto function in campaign? I really hope we will always be able to use semi auto with the SCAR in single player, not just as the occasional attachment like multiplayer!

I am pretty sure you can select firemode in singleplayer(Burst, Semi and fulll auto. Burst will ofcourse be for compitable guns)
Also i think you can select/deselect attachments on the fly

wow that would be great, i assumed you could but since the new Crysis has been "streamlined" I didn't know if that customization was absent in Crysis 2. Based on multiplayer demo, I really hope they allow you to use semi auto whenever you want!

You can do that in MP as well . I'm doing it in the demo, because it gives a lot better accuracy from the hip, allowing me to to slides, while killing people . You just have to hit the left Dpad (on Xbox), let's see, what it will be on PC.

Well I know you can in the demo, but I'm really worried about single player. In single player, I hope that all SCARs or assault rifles with a semi auto option allow you to switch to semi auto, and not just ones that don't have attachments like in MP. I hope in single player I could ALWAYS use semi auto, even with a shotgun or grenade launcher attached.

Yes, the SCAR has a semi-automatic capability.

I understand it DOES have a semi auto function; I use it in the multiplayer demo. I mean if I were to start a single player mission with the SCAR, would I be able to use semi auto at my own will, or only if I didn't have a grenade launcher or something taking up my secondary fire ability slot (like it does in MP)?
