I dunno... I play crushing with Rai every one e and a while and he gets $100000+! Then again, a only get around 50000 each time...
co-op caps at $100,000, there is no way to get over that, and he would pretty much have to complete all 10 rounds completely by himself to get that much money without double xp
edit: i didn't notice this was an old thread
200+ kills in a match is not something to be proud of. It is a warning sign to me if I see a player's stats pre-match yield greater than a 200 NPC kill per co-op complete ratio. It signals to me that they are either:
a) not very efficient with their weapon use and not working well as a team to avoid round restarts, and/or
b) have a style of play that can lead to lower-than-desired match completion percentage.
Efficient crushing matches will have kill totals for the whole team combined of under 200, with that number varying on how many rounds are Gold Rush.
When playing with randoms, I view 200+ NPC kills per complete as potentially dangerous, and those in the 160-200 range to be cause for a little concern. If the whole team has ratios lower than 160, I feel a lot more confident about completing a crushing match with very few, if at all, team deaths and restarted rounds.
