Snow Base

"We've discovered a hidden snow base. Halt production of their new weapon."

- Stage description

Snow Base is Frost Walrus's stage in Mega Man X4.

Snow Base Area 1
The first half of the stage has two paths. The upper path can only be reached with a Lightning Web wall jump with X/ or using Kuuenbu (double jump) with Zero. It contains a few extra lives. The lower path contains snow platforms that will crumble after a few seconds, as well as a Life Up on top of a block of ice that can be destroyed using Rising Fire/Ryuenjin. Next is a small section with small platforms and spikes, followed by a section with snow slopes that slowly crumble over a bed of ice spikes. If one is to wall jump to the top of wall to the right on this section, there is an EX Item which can be reached with a Lightning Web with X/Kuuenbu (double jump) with Zero. After reaching the bottom part, there is a small section with rising ice platforms that will crush X/Zero if not careful enough. At the end of the section, there is a fight with the Eyezard sub-boss.

Snow Base Area 2
The second half of the stage has ice blocks which sometimes contain enemies or explosives inside. Both paths lead to the same exit of the section. Near the end there is a Weapon Sub Tank inside an ice block. Next section features Ice Wings which if not destroyed in time, will freeze a portion of the stage, making the floor slippery as well as spawning ice spikes and freezing enemies. If these frozen enemies are destroyed, they will fire ice spikes. At the end of this section is where Frost Walrus awaits.
