The Fourth Chapter in the Mega Man Saga
One Year After Mega Man's Battle in Space...

After restoring peace to humanity's perilous mining worlds, Mega Man has enjoyed a brief year of respite.
But now, the world is once again thrown into turmoil as eight cities are overthrown by rampaging robots!
Is this the work of Dr. Wily? Or some mysterious new enemy!?
Mega Man sets forth to take down this threat, equipped with the new Mega Buster!

・The gameplay and difficulty of this version have been optimized for smartphones,
so certain elements will differ from the original game.

◆New Feature
The "Mega Buster"!
Mega Man 4 was the first game to feature the chargeable Mega Buster.
Hold down the attack button to charge Mega Man's arm cannon,
and release for a devastating attack!

◆Sliding Controls
Hold down + jump while playing to slide.
Use this technique to move quickly, dodge attacks, and fit through narrow spaces!

This version features a choice of two difficulty modes.

・Normal Mode
Unlimited continues.
The continue screen is displayed whenever Mega Man dies.
Selecting continue allows you to restart from the last
checkpoint you passed in the current stage.

・Hard Mode
This challenging mode limits your number of continues,
and enemy attacks deal more damage.
There are also fewer checkpoints within stages.

The following settings can be adjusted in-game.

Increase the number to raise the volume.

Set to "On" to have your device vibrate when Mega Man takes damage.
(Default setting: On)
Note: This option will not be displayed on devices with no vibration function.

Auto: Hold the attack button for rapid-fire Mega Buster shots.
Manual: Each press of the attack button fires one Mega Buster shot.
Tap repeatedly for rapid-fire shots.
(Default setting: Auto)

Choose between Normal and High to adjust gameplay speed.

・Key Config
Change position of the in-game attack button and jump button.

No controller support

I don't understand why this game doesn't have controller support, especially considering version 1 came out less than a year ago. The D-pad on the iPad version is way too big, and the action buttons are too far spaced out to use efficiently. You can switch button configurations, but there are no other options beyond that. The game also uses no touch-optimized controls even when they would make sense (choosing a level, options menu, etc) further confounding why there is no controller support.

In addition, the game runs very sluggishly, skipping frames often and feeling very "floaty" on the so-called normal speed. At first I thought this was to give the game more of an authentic 80s console experience, but it was definitely never this bad.

In short, this is an incredibly lazy port of a great classic game. Kind of a shame, and I hope they update it to fix these problems (but I don't have my hopes up since this is Capcom we are talking about and the game is like $1, hardly on the top of their priority list).

I Love Mega Man

First off Mega Man IV is and had always been somewhat on the difficult side. The controls are difficult and sometimes you jump or slide when you hit the “fire” button, small but annoying bugs. BUT there are many compromises. In the teleport hatches (and after every stage) you get your health meter regenerated after each boss (+) have infinite continues (+) and yes the Robot Bosses are psychotically difficult (-) with crazy attack patterns (-). I am addicted, especially after the Boss rush. This is literally the only game I can’t blow through 3-4 rounds (actually my record is 8-9 bosses in a row). It’s almost like it’s own game in a way and not just a port.

Holy motherflip

This. Game. Is. Trash. I feel robbed! First, you nerfed the bosses to do as much damage as the stompers in mm1 which do like a quarter of your health each. Next, there's the fact that UNFAIR JUMPS ARE PLENTIFUL. Dive Man- oops the spikes were a Pixel lower than I thought I'm ded. Toad man- the rain that only affects you while your jumping which might not seem bad but to get to the non-rain sewer you need to PLATFORM and the jump towards the second snail has DEATH PITS!!! I overall want to rate half a star. This is the worst mega man game I've played.
