I didn't see this topic covered on Tilt's TWD wiki sheet... and figured this thread makes the most sense to post this question:
Do multi-kill shots award MULTIPLE walker kills in one shot?
Here's a copy/paste of what I posted on a Slimside thread on Last Man Standing regarding my idea for multi-kills:
"Instead of using the PFx or the inlane X, which are already lucrative enough for scoring, I think a reasonable way to award more walker kills would be to make every stacked multi-kill shot (within the same ball) award +1 walker kills. It is, in fact, called a MULTI-kill. You should get credit for MULTIPLE kills on multi-kill shots. Or is this already the case, and I just haven't noticed?
Further, if you qualify multiple multi-kills on one ball, your # of walkers killed per multi-kill (MK) should increase.
Example: You start your first MK on ball 1. You shoot an MK shot. Instead of just getting 1 additional walker kill, you get two (1+1, because you've started one MK). You shoot the next shot that's lit for MK, and once again, get credit for 2 walker kills on that shot.
You continue playing a good ball one and qualify another MK on your next mode. Now each MK shot should be worth 3 walker kills (1+2, because you've started two MK's). Qualify another MK during ball one? Then each MK shot should now be worth 4 walker kills (1+3, because you've started three MK's).
Once you drain out of ball one, and no longer have a MK lit for ball two. When you qualify your first MK during ball two, you're back to your MK only being worth 2 kills per MK shot.
I think this would be a great way to make multi-kills worth shooting for when you're playing for walker kills, because it provides incentive to play modes/MB's well enough to qualify your MK shots.
