Is it unlocked yet or will it still give out "Unknown Command" lines whenever you put in weapons for single player? I haven't checked back on Crysis 2 since release after I beat it, and a Google search brought up no results.

you're probably typing something wrong. I'm no expert at that but probably some expert will bump on this and reply something useful just bumping it

Nah I'm typing in the codes right, but the console was locked (when I checked at release, I think it was from 1.2 patch and forward) so when you tried to put in a command for weapons/energy/god mode etc. it would just say "Unknown Command" as a way to reject the code so people wouldn't cheat on MP.

But I'm not sure if they patched it back so the console commands won't affect multiplayer and just affect single player.

It's still locked

Dang
