Can you please add the option to log the announcements like  "... got the last hit on helicopter" to a logfile/console?

That's definitely possible! What would you use it for?

I would like to have the option to retrace who killed the helicopter and when. Sometimes helicopter spawns just couple minutes before a restart and i had the situation that players killed it and got nothing from it.
So basically to have clear evidence if heli got killed, when and who killed it.

Ah yeah sure fair enough!

Any news to this?

Sorry mate, no news to give yet.
