Emergency Supplies

From the save room at the right end of the 13x1 blue hallway, go right to the shaft. Take the left door midway up to a longer room.

Jump onto the grey platform, shoot leapers and spawning enemies, then go left past three spawning pipes and jump the gap. Shoot spawning enemies near the first pipe. Drop into the second pipe and shoot downward or use bombs to enter a hidden area. Shoot or bomb the grey ledge above the lava, then drop into the fake lava. Turn right and shoot the wall to reveal a missile tank. Roll into it.

Climb out and head left past more leapers and spawning enemies. Enter the door at the end of the room.

Roll left and jump to the tunnel below. Set bombs to free enemies above. Kill them and collect their items, then grab the missile tank on display.

Jump left and pull yourself up into the small alcove. Set a bomb to create a passage above. Jump left, pull yourself up, then jump right and crouch. Fire a super missile at the block on your right. Roll right and set a bomb when you can't go further. Watch the blocks disappear, shoot the remaining block, and grab the super missile tank inside.

Work your way back to the ground floor, then roll left and continue through the door.

Crouch and freeze an enemy when he's on your side of the missile tank, then use him as a platform to jump up to it. Jump left and grab the grey ledge, pull yourself up, and go through the door.

Kill all leapers in this room as you head left to the next one.

Jump the wall and grab the super missile tank. Roll into a ball and jump against the right wall above to land in a hidden passage. Follow it. Shoot the block above you and grab the missile tank inside. Use the door on your left.

Roll into a ball and roll left into the shaft. Quickly exit the ball and grab the left tunnel as you fall. Jump right and grip the tunnel you came through, then jump left to the tunnel and the missile tank above.

Roll right and exit the ball as you fall to grip the left tunnel below. Shoot diagonally down at the block by the missile tank. Jump into the air, quickly roll into a ball, and hug the right wall as you fall to grab the missile tank.

Fall to the ground and use the launcher in the bottom right corner. Return right to the 1x1 room past the leapers.

Drop to the bottom of this shaft and use the save room on your left before running through the door on the right side of the shaft.

Continue running right as your Speed Booster kicks in, barreling through enemies. Collect their dropped items and go through the door ahead.

Roll right and set a bomb by the wall. Drop to the passage below and head right for an energy tank before heading back left to the save room.

Go left to the next room and jump over the wall, killing spawning enemies. Approach the enemy on the door ahead. Wait for his eye to open, jump over his beam, and launch a missile into his eye. Repeat three times. Pick up the dropped items and go through the door.

Continue left to the next room.

Approach the statue and break open the container to grab the Unknown Item. It is incompatible with your current suit.

Jump over the statue, shoot the 2x2 block, and continue left through the wall to grab an energy tank. Return right and use the statue to restore health and missiles. Switch to super missiles and enter the next room.
