Barn didn't seem to change much. I thought there were additional rules about the type of zombie on the DMD and that related to scoring somehow maybe the base value? Every additional shot seems to go up by 250k. Similar to the old scoring but the base value is higher. My best Barn is 120M
CDC was fixed to work as originally intended. Repeated CDC ramp shots light other shots with red arrows maximum 4 ramp shots I believe. Then hitting the lit shots increases the value you are able to cash out at the ramp. If you hit one of the lit shots before lighting all of the shots you can not light additional shots at the ramp only collect. You can hit other lit shots before cashing out though. To cash out/complete the mode you need to hit at least one of the other shots and the CDC ramp twice.
Riot didn't change at all except the dots maybe. Shoot riot shot and get points that go up in value with each shot.
Tunnel is similar to CDC as far as I know. I can't confirm the 3x but I believe the 2x is correct.
Arena is similar to the previous code version and hasn't change I believe. Shooting the ramp gives points and consecutive ramp shots award more and more points.
Multi-kill is a real!! I think I heard Josh say its 1/20 of your mode values? I've had one at 8m a shot and with 2x and shot x it can get juicy. If you drain out you can just start a new MK and the value doesn't drop.
My base strategy now isn't much different than my old strat. Go for bloodbath ignoring everything else until its qualified. Now I like to get well close before starting bath. Well in the old code was garbage but in the new code I generally get 20-30M. As soon as well or bath starts I start Barn asap. After Barn starts I try to bring in Well if not already started. During MB I hit drops to add balls as needed. Make drops ready and try to cradle up and go for barn as well as letting balls drain during BB or Well ball saves.
I think this is one of the strongest stacks in this code version since Barn is feeding pops for switch hits to basically automatically progress through and light well JP's. Adding balls counts for mode time and switch hits and BB jps and sjps. The points alone from Barn will be worth a lot and when combined with the jps and sjps from well and BB it can get really nice, especially with 2x added in the mix.
Sorry I don't have specifics for the mode scoring but, try stacking this stuff though!!
