I came across this line of dialgue, and I'm wondering what the lengthened
version would be. For context, the series is in the middle of a tournamet
(there are teams, but players compete individually), and one player has just
witnessed another player winning their match with incredible skill. The
spectating player thinks:

> オレたちゃここまでだな

I've translated that as 'We're finished/this is it for us', going on the
assumption that オレたちゃ is a contracted of オレたち and another word.

Could someone tell me exactly what the long form of 'オレたちゃ' is? Or am I wrong
and is 'たちゃ' another word entirely?
