Ok so to begin this will be a walkthrough  guide/series and will contain three parts, I am dividing the game into three parts because I don't wish to spoil the game and because the game has nine stages/missions you have to beat before the game is complete. SO without further a due, let's play some Metal Warriors!

Mission one ,Rescue your fellow mecha pilot. , in this mission you are tasked with the objective of  locating and rescuing agent/private Marissa and get her out of the stage (enemy base) . From  the beginning  of the stage, fly towards your right until you reach the elevator and the platforms, then proceed to go down one and then head right until you can't go further. The while in your mech shoot through the floor and continue down the course to the right. Next, fly up  the opening until you come come to an orange wall then keep right. (if you wait a bit a enemy will spawn and blast an opening through the right of the wall or you can get the rocket launcher equipment and break through yourself) But after that continue right and destroy the cannon, then continue right, along the lower path to a large room filled full with orange blocks. While in your mech shoot your way through the blocks to the lower left corner of the stage/room to find the missing pilot. After picking her up in your mech, fly straight to the left, once again shooting through orange blocks and keep left until at which point the mission(stage)ends.

Mission two:, Hijack the enemy ship, in this mission your main objective is to seize control of the enemy ship, you basically just make a mad  dash to the operating center of the ship itself.From the beginning
of the stage, drop down the shaft , then continue right along the upper path until you walk into a room with huge missiles.then proceed to go up and to the right until you reach a point where your mech is to big to fit through the path. When you
reach this point simply hit (whatever your select button is) and jump out of your mech and continue to follow the path to your right until you reach the end of the mission(stage).

Mission Three: ,
Infiltrate and Secure the enemy's base on the asteroid.Here's where it gets slightly complicated, First when beginning the mission(stage), go right until you reach a  vertical shaft, then fly to the top of that shaft and go right.Shoot down through the orange platforms and then go to the right until you get to a cannon on a ledge above you.  Shoot the cannon and go to the right. Then  drop down and jump out of your mech (using whatever button is your select button) and fly to the right and shut off the "On" switch.  Now get back in your mech (also by using whatever your select button is) and fly to the top of the shaft.  Go to the right until your commander that says you've (Lt. Stone) captured the central computer. Now, you must protect the Central Computer Core.There are these five core generators on the wall (they are numbered 1-5 and look like orange circles with a glowing dot in the center).  You must protect at least one of them from the enemies that are flying around trying to shoot them(protect atleast 1 to get passed this part) until you are told by the commander "Good work, now go to the hangar". After saving the core, shut off the "On" switch at the bottom of the room and then follow the lower left path until you find a life power-up.  Ride the elevator up one level and go left until you get to the gun turrets on the enemy drop ship.Shoot the three gun turrets on the top of the ship, then get out of the mech, drop down into the ship, and go to the right side of the ship where it says "Ship Com".  Then when you are basically instructed by the commander to guide the ship back into the base, just push right (whatever your right button is ) to move the ship until it stops. The it will say Mission(stage) complete!

This is the end of Part I of my guide for Metal Warriors, and encase of  formatting issue's I do apologize (I have been having trouble with the format messing up) Edit:I made it worse by switching to old post editor.
