Damn...you guys should really see what kind of challenge Ryu was taking in the Eternal Legend mission.
This was the ET gauntlet:
Feudal Phase
Ryu fights off several ninjas at once in the first floor of the emperor's palace. He then proceeds to the second floor and fights off even more deadly ninjas who use windmill shurikens. He proceeds to the third floor and kills a bunch of bats.
He advances to the fourth floor and fights the same kind of ninja's he fought in the second floor except there are ninja's that have fire-based katanas. There are also floating samurais who shoot multiple balls of energy at you. Ryu ascends to the top of the palace and enters a portal that leads him to a realm similar to the Fiend Realm.
Boss: Two samurai horsemen.
Military Phase
Ryu fights off a series of soldiers armed with stun batons and pistols. Afterwards, he is ambushed by near-futuristic soldiers who are equipped with heavy armor and plasma swords.
After that, Ryu faces off against the Vigoorian heavy infantry. These soldiers are armed with machine guns, rocket launchers, and grenade launchers. After Ryu kills those, several futuristic versions of the Vigoorian infantry appear. The weapons they use are futuristic as well.
Boss: Cyborg Captain who uses a built-in electric gun that shoots blasts of energy at his opponents.
Fiend Phase
Ryu takes on several fiends that are quite easy to beat. Then, he takes on another encounter of lesser fiends. After that, Ryu fights off 30 giant bugs.
Boss: The Ice Fiend Hydracubis, along with other lesser fiends.
Ryu then fights off six ghouls armed with axes and bows. Ryu then fights 12 wasp fiends along with 6 lesser fiends and 2 ghouls.
Boss: Yotunfrau, along with lesser fiends.
Ryu then fights off a bunch of soldier fiends along with a ghoul fiend. Ryu then fights against stronger fiends along with 6 other fiends with large pincers and energy rays. After that, Ryu kills 12 giant bugs along with 4 giant ogres armed with clubs.
Boss: Doku, one of the Greater Fiends in NG, along with other samurais. He uses the Kitetsu which is a cursed japanese sword that feeds on the souls of those that it slays.
Boss: Marbus, Lord of the Fiend Realm, along with all kinds of fiends.
Then, Ryu faces off against 4 Vigoorian Berserkers who came out of meteors. They have a second form that is triggered after recieving a certain amount of damage. This new form makes them more powerful and agile with their attacks. They can shoot bigass fireballs and can create some form of mine underneath you wherever you are.
Boss: Nicchea, along with middle class fiends. Nicchea is one of the ancient greater fiends.
Boss: Ishtaros, one of the greater fiends in NG.
That's the end of it. Afterwards, it shows Rachel being freed from the stone tablet that she was encased in originally. Ryu shows no signs of fatigue whatsoever. The end.
