In short, when you complete an objective in the game you'll get a multi-kill which is the yellow insert you see. Anytime you make the yellow insert shot, it'll randomly move to a new shot. In addition, when you get a multi-kill; the type of multi-kill is represented by a flashing weapon insert. Which weapon is chosen to represent the multi-kill is still unknown to me. Im also unsure how the base value of a multi-kill is determined, But the more multi-kills you get during one ball the bigger the value the yellow multi-kill insert is worth.

Once your ball has ended, the weapon inserts will light solid representing that the multi-kill is over. Get all weapons lit (flashing or solid) and hit woodbury for some fun!

Hope this helps. Reading material for your pleasure:

I am wondering this a bit too. Overhead through most all of those threads and watched some tutorial videos, but some of the MK starts are a mystery to me.

For example, yesterday I had BBMB and WWMB stacked with Riot. By the end of it I had 5 flashing weapons going. I'm not quite sure what all the objectives are, also, I'm not sure how the weapons "stack". Does it just add value to the base jackpots? I isn't notice multiple yellow lights at the same time, so I figure getting more objectives complete, doesn't light more MK lights.

I was very surprised I completed 5 things from those 2 MBs and 1 mode. I figure maybe BG worked into that? Where else can they come from?

This aspect is one of the foggiest parts of the rules for me still at this point.

Yea. Only 1 flashing light and the MKs accumulate the jackpot value to it.

You can earn MKs for the following:
During Each of the 5 modes
Completing bicycle girl
Completing the bank of drop targets a certain # of times (6?)
Lighting the xbow a certain # of times (need to confirm)
And you might be able to get them for Super jps in the 2 main mb modes also? (Unconfirmed)

MK values are 5% of all your mode scores throughout the game. So if you've had a 50m Barn and a 50m Arena, your MK value would be 5m. These can be doubled,etc with inlane x and playfield 2x.

In the latest software, you also get credit for 2 walker kills when you hit a MK shot that is lit for a walker kill.

These are all excellent details and exactly what I was looking for... Thanks for the insight!!

And now, for a slight derail... can someone explain how BG scoring / mode works?
I see it counts down from 1.5 mil and you hit her in the face (Prem/LE). But one time I started it and hit her for 7.5M. This confirmed that I have no idea how it works and not sure what I did. Thoughts?

You made the shot with an inlane multiplier

But wouldn't the inlane Multi just make it x2 to 3M or even if 2x playfield was going, 6M?

I could be wrong, but I think you can also earn a multi kill for completing the fishtank a certain number of times.

Not if there were more than 2 walker kills saved up in the inlane X. Not sure there is even a limit to that multiplier.

No, inlane multipliers continue to stack, indefinitely as far as I know. you get 1x for every two walkers killed. So if you've killed ten walkers since you last used your multiplier, the shot is at 6x.

Now that multikills actually kill more walkers, I'm guessing we are going to start seeing some insane inlane multipliers. Think about it. Just four successfully made multikill shots gives you a 5x multiplier.

Pdxmonkey just told me he made a 180mil point shot last night with 5x multiplier and riot going and 2x playfield. Crazy.

And, this is why it's the best code they've produced since ACDC.

I had an opportunity just like this last night ..... Started Riot. Nailed it a few times. Started 2x playfield. Nailed Riot a couple more times. Shot the left ramp. Rolled over the lit inlane multiplier. Bricked the shot.

Basically these give you multi-kills (taken from TILT forum):

Three Barn shots during Barn mode.
Three CDC ramps during CDC mode.
Completing CDC mode.
Three Riot shots during Riot mode.
Two Tunnel shots during Tunnel mode.
Completing Tunnel mode.
Two Arena ramps during Arena mode.
Completing Arena mode.
Completing the Bicycle Girl hurryup.
Clearing the drop target bank 10 times.
Clearing the drop target bank three times during Blood Bath.
Scoring three jackpots during Well Walker multiball.
Scoring four jackpots during Prison multiball.
Completing three crossbow shots.
Collecting the Start Multi-Kill award.
Completing three fish tanks.
Completing two Woodbury skill shots.
Making 10 combos.

Do 6 of these in one game and HORDE will be lit (started at the Woodbury shot)

Making lit multi-kill shots (yellow circle insert) give 5% of your mode scores on that ball and also score 2 walker kills (as of 1.56 code update). I cannot underestimate the importance of multi-kills in the game now and yet another reason why it is so awesome and that Lyman is king!

Seems like I heard Josh Sharpe say it was 5% of all mode scores played throughout the game, not just per ball. Can anyone confirm this?

It's per game, and definitely carries over. Getting the multi-kills relit after a good ball can be worth a lot more than multiball.

Multiball also adds to multikill value so don't ignore it! If you can manage an inlane X coupled with 2x super jack on prison or well (Using a bomb makes this much easier) your MK values will skyrocket and in turn the Horde value.

I have my settings harder (more shots needed in the modes): otherwise Horde is too easy.

Yeah sure make it even harder...why not

Reached horde only twice in over 500 games, and that was just lucky!

So many rules ...so confusing

Damn hard I say, lucky to light up 2/3 weapon inserts

This might be important if horde was the wizard mode of the game but there are tons of other things to do. I think you should get to horde frequently.

Actually I prefer Horde to be more difficult for another reason.
I have my game on 3 balls, and mostly get 1 xtra ball, rarely two xtras.

With multikills on default, I reach Horde a lot.
Horde itself is designed now that I almost never get bit... I always end that mode because my last ball has drained. And I even have the advance walker at it's maximum. Bit gives you you're ball back (keep shooting), a drain doesn't..
This way I have less chance at Last Man Standing.

If Horde would be different in that matter, it would be different.

When I get mine in a few mos I fully plan to take the glass off and finger the switches and figure it all out.

Hehe I hear it works best right between the flippers. Be sure not to go in the outlane.

Appreciating this thread. Can't wait to play some more tonight. Thanks!

Wish I could play mine tonight, been waiting on mine to be made (pro)and shipped. Hopefully soon.

Man, I am chomping at the bit to get home and play tonight. I hate how much I love this game, and I love how much I hate it everytime the ball rolls down an outlane.

Played a pro on location yesterday for the first time in a month or so. After a few crappy games I put 224M on it. Got to Horde again. I heard a new sound throughout Horde. Pretty cool repeating sound almost like a heartbeat. First time I've heard that, must have been in the last code update.

It is a heartbeat so to speak. It goes along with the music in the game. The flashers actually pulse with it in the Prem/LE version.

Start at 17:00. Thanks to Keith Elwin for a spectacular video!
