@harryexplorer:
Hmm... about the "backfire" line...
In Japanese the line reads:
送弾不良が無かったら…
立場は逆になっていた
Or, very literally:
The bullet was sent bad, it wasn't there...
The position became reversed.
Through my localization, I thought she was talking about backfiring, but now I think she's literally just saying the bullet was reversed in the feed and caused his gun to get jammed, like you said. Thanks for the insight! I'll probably re-localize it and update it with a v2 at some point.
