Screen 6 - Underwater Screen

Take advantage of the walls and slide all the way up to them. Jump and shoot the Mets as needed.

Be careful with the jumps and proceed as quickly as you can. 

As a reminder, you cannot jump out of slides underwater in Mega Man 4

Safe way - Damage boosting

Here we will stay on Buster. But this can be scary to move properly in the water especially near the end. Scared? Well time to do some damage boosting! 

The first damage NEEDS to be a back damage boost, else you wont have enough iframes to go through the spike safely

Damageless strat

We are going to cut some of the unnecessary damageboost to clean the room up, but without doing some risky stuff

Optimal strat

If we wanna optimize, you can kill the Met and jump all the way to the top ledge in one jump

While the reason might seem strange, you do actually save time by doing this as you avoid bonking the wall

Dangers of this room

When you are barely not full health, you may encounter what we call Death Drops if you speedran Mega Man 3, you might already know what are we leading to.

Met dont deal a lot of damage, so its very likely you might have gotten one hit by a Met in the previous rooms. In other words, if you are not ready, this Met is very likely to kill you

You need to be very careful, to not jump to far right as a drop can kill you A input very easily

What About Rush Marine?

Besides the obvious talking points of Rush being slower than sliding, and switching to rush being an extra animation, Rush Marine simply does not fit through the spike gaps.

While potentially useful if you are uncomfortable jumping through spikes underwater, Rush Marine should be avoided.

Spot to menu

For the next following rooms, we actually will need Rush Jet.

The best spot to menu is right here, as you fall off the ledge

As a reminder - if you pause on the ladder, mega man will release the ladder when you unpause the game. DO NOT hold left out of a pause here, since the spikes are next to you.

World Record stuff

Since you cant jump out of a slide underwater, you can perform some slide cancels, like in Dive. Although, very hard to save time with them. Here's an example with the fastest time of the room : 13'06 by Chelney
