The second Strider episode is a version from NES, I never heard about it, and it's kind of "metroidvania" actually.
The game's ideia is simple, you have to always find a floppy disk in the stages and go back to HQ to analyze and unlock new areas on the map! At the beginning it's confuse, but it's just read the texts that it always helps.
The game has several Upgrades and Power Ups, I did not use half of this list, and it seems that I left some items behind. One thing I don't remember was if I had already taken the super jump before this part, I spent an eternity to do the Wall Jump, believe me, it's too hard!!!
You can get stuck if you don't speak english (I think it's no problem for you) and with this wall jump meme! The penultimate boss that you HAVE to face with MP to kill him, also made me lose some time!
One fun fact is that apparently the game is based on manga from Strider Hiryu. And definitely this version has nothing like the arcade game, it seems they are different characters actually...
