Just wondering, does the silencer in Crysis 2 multiplayer work the same as in COD? Where it stops you from being revealed on the map when you shoot. Or does it just muzzle the sound?? Thanks to replies in advance.

Both, but it also reduces the damage by a fair bit from what i hear

IDK about the damage thing since it dosent show that but it also shows you lose some mobility with the weapon when you put it on

And you can fire a few shots cloacked with silencers.

Well, if it's like the SP, it allowes you to shoot one or two times while being cloaked without loosing the cloak (it just costs about 20% of suit-energy so no full-auto-cloak-shooting).
Can't really say anything about the radar as I didn't saw anyone using a silencer yet.

Thx for replies. Just FYI about how silencers affect damage of weapons, got this from Denkirson btw.
"Silencers do not alter damage, but they typically halve the maximum damage Distance."
