Would it be possible to have a separate file that you open and you can edit text that appears on screen when you get a multikill. For example, if you made a Halo mod you could make it go "Double kill, triple kill, overkill, killtacular etc". And if you were making a Perfect Dark Zero mod you would have (These are pretty funny): "Killtastic, Killtropic, Killmatic, Killegal, Killcount Karnage, Mambo Killosso, Killharmonic Orchestra" You could then make other well known variants like m-m-m-m-monsterkill. It doesn't actually need editing, but hey, it would still be cool.
Aslo, could we see a killing spree type recording as in if you get 5 ills in a row, where all the kills are appering in the top right, it come up with "Gnoblar is on a streak of 5 kills" or "Gnoblar, is on a killing spree" (Like in TW, but not a server message).
I just think these would be good.
