# Cossack 4

The End?

# Screens 1-4

### Screen 1

Slide off the ledges to the right. You might wanna start charging here without releasing, see [Stored Charge Mechanic](https://goodboyrush.net/link/147#bkmrk-stored-charge) for more information about it

<p class="callout info">If you need the weapon refill (presumably for Pharaoh), switch to the weapon and hold right against the wall at the screen transition. While the record route does not need this refill, it is highly recommended for beginning runners and all racers to collect this weapon drop for Pharaoh until they are comfortable now needing Pharaoh refills.</p>

### Screen 2

If you need the weapon refill for Pharaoh, hold right during the fall to collect it.

Otherwise, just fall through and slide to the right.

<p class="callout info">If you dont plan on taking the E-Tank Switch to your desired weapon for the next screen - Balloon is optimal, Coil is backup/safer strat.</p>

### Screen 3

Jump and tap right to back-boost through the cannon. Continue sliding to the left to fall down.

<p class="callout etank">If you want the E-Tank, just hold right during the fall. This requires an extra weapon swap to Drill to break the wall, but otherwise does not impact the route.</p>

### Screen 4

Slide to the right.

The stomper or Jumbig, as 2 jump patterns variant. The low jump is the bad one has it will stay on screen as you damage boost through it. The high jump is the best one, as you can despawn it quicker and reduce lag by extension.

There's various strats you can do for the high pattern.

##### Slide below him

<p class="callout warning">This strat is not easy as you need fairly precise movement to not get hit, getting hit result in getting another hit from the spark ball loosing a bit of time and health</p>

##### Early damage boost

This strat is supposedly ever so slightly faster or tied to the one up there, but it is much easier to execute

Notice that you wanna take the damage boost before passing this line

[![Mesen_WYnd5mpkFt.png](https://goodboyrush.net/uploads/images/gallery/2025-09/scaled-1680-/mesen-wynd5mpkft.png)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-wynd5mpkft.png)

Else, the spark ball will spawn early and you wont be able to make it without taking an extra damage

<p class="callout info">You can technically (in case you messed up) dodge the spark ball. Though note that wiggling can be quite laggy or slow, the difference isnt all that massive so if you are scared of health in this stage, do that. </p>

<p class="callout warning">You can't jump out of a slide in front of a ladder. Yes! you are not crazy if you think it eats your jump sometimes! Thats why if your movement is ever so slightly suboptimal, you may want to take a step before jumping.</p>

# Screen 5 - The Shortcut

There are two paths through this screen. Going to the top right is faster.

### Balloon

There is a tight space to get a balloon jump and not bonk on the platform above. This is the fastest method as it does not have Rush's pause animation, but it can be tricky.

There's also 2 ways to place it.

##### High placement 

This one involves doing a small right release to do a straight jump to place it higher.

[![mm4-cossak4-screen5-balloon.gif](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-screen5-balloon.gif)](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-screen5-balloon.gif)

You can then proceed to menu and get rid of the wall as you start falling

[![Mesen_l2cRURmKdi.gif](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-l2crurmkdi.gif)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-l2crurmkdi.gif)

##### Low placement

This one can be either easier or harder depending of how you feel with the game.

There's severals advantages this can give you.

1. Don't need to right release for the placement
2. Gives you near perfect height with a max height jump to land immediately on the small ledge (no need to adjust like the heigher placement)

[![Mesen_9snF72pLct.gif](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-9snf72plct.gif)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-9snf72plct.gif)

### Rush Coil

Simply summon as you grab, and jump on top of it to reach the top

[![mm4-cossak4-screen5-coil.gif](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-screen5-coil.gif)](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-screen5-coil.gif)

You can optimize the jump by letting Rush boost you instead of jumping on him, this gives you less height so you land quicker on the top ledge.

[![Mesen_aZdIM9srcm.gif](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-azdim9srcm.gif)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-azdim9srcm.gif)

<p class="callout info">This is slightly slower due to the Rush Coil animation in the menu. It is however easier to execute, since you can jump against the wall then fall straight down onto Rush.</p>

### Next Steps

Use drill to break the wall. Then fall down with Drill still equipped.

<p class="callout etank">There is a potential E-Tank at the bottom of the fall if you still have Drill equipped. This is a useful backup item, but not needed for WR attempts.</p>

# Screen 7 - Slinkies

Collect the E-Tank if desired, then drop down.

Slide to the right, and use drill on the slinkies. Switch to buster at the end and proceed.

### 4 jump strat / Safe strat

Simple, one jump, shot, jump then repeat.

### Faster strat

This time we try to kill the slinkies in one single jump. You need to shoot fairly early or else you will get it (most likely on the 2nd one if you are too slow or too far)

[![Mesen_MgD36eAtyZ.gif](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-mgd36eatyz.gif)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-mgd36eatyz.gif)

### Stored Charge Mechanic

You can hold a full charged buster, switch to another weapon and once you go back to Buster get an instantaneous full charge.

Exactly like this example right here:

[![mm4-cossak4-storedcharge-demo.gif](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-storedcharge-demo.gif)](https://goodboyrush.net/uploads/images/gallery/2024-07/mm4-cossak4-storedcharge-demo.gif)

You can use the stored charge technique on the slinkies here. Technically the slinkies take two hits from the drill bombs, one from the contact and a second from the explosion. You can switch back to buster after the contact damage on the second slinky to save a small number of lag frames and start your slide ever so slightly earlier

[![Mesen_j34djp7PaZ.gif](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-j34djp7paz.gif)](https://goodboyrush.net/uploads/images/gallery/2025-09/mesen-j34djp7paz.gif)

You can also use it with the safe strat!

# Dr. Cossack Himself - Cossack Catcher

### Damage Table

<table border="1" id="bkmrk-buster-1%3A1%3A3-dust-cr" style="border-collapse: collapse; width: 100%;"><colgroup><col style="width: 50%;"></col><col style="width: 50%;"></col></colgroup><tbody><tr><td>Buster</td><td>1:1:3</td></tr><tr><td>Dust Crusher</td><td>2</td></tr><tr><td>Wire</td><td>1</td></tr></tbody></table>

### Buster Strat

The Cossak Catcher has an interesting quirk - it stops moving if Mega Man slides. You can use this to essentially freeze the Cossak catcher in place, and work on optimizing full charge buster shots.

Remember the Catcher fight ends on its next move once reduced to 2 or fewer HP. You should try to move towards the left side of the screen (jumping left off the high ledge) for the last hit if possible.

### Dust Crusher?

While Dust does extra damage to Cossak, Buster is the superior choice with castle routing. This really boils down it being faster to just use buster than it is to both use 12 Dust shots and then collect the ammo later.

### Region Differences

1. In the North American release, the Cossak Catcher takes an extra few seconds before moving at all, letting you get some free hits.
2. The english text, as ever, is slightly slower
