Beating the Unbeatable achievement

I didn't know it was a megaman x type of boss where you can actually beat the two in the prologue. Were you supposed to run somewhere? I'm still on the first playthrough and just got it.

For the encounter at the end of the prologue
If you die, Vana finds you badly damaged and takes you back to gear village to get fixed by Olga. This is the most common outcome, expected for most players in their first playthrough.

If you win the encounter, possibly by continuously parrying the monsters and hitting counter attacks, Vana finds you, congratulates you for beating them and gives you a weapon, and the story progresses to Gear Village as normal.

Nice, so the fire sword and what not were extra rewards, I love it when games do that.

[that hurts]

i myself beat the encounter by dodging and using the automatic gun that you can craft

It's a cinch on NG+. I say don't try to get this on your first playthrough.
