Goal: The objective of each level is to get to the goal before the timer runs out. On Eliminate All levels, you must also eliminate all the guards in a level.
Weapon Mode has a total of 5 levels:

Bomb Disposal Mode has a total of 5 levels:

This level is seperated into two subcategories: Glitched and Glitchless.
Glitched:
At the start of the level, restart once. Head into the room and circle around the guard that notices Raiden. Head back out through the northern door and once the other guard faces south, diffuse the bomb.
Now, head over to the locked door that heads to the AB connecting bridge and perform door glitch.
If done correctly, you will now be out of the bounds of the VR level and can explore the rest of Shell 1. If you did NOT restart at the start of the level, the player will be unable to move.
The reason we head out of bounds is to loot all of the weapons available in Shell 1 and then head back in bounds of the level to raise our weapon bonus.
Keep in mind that while out of bounds, the Sneaking and No-Kills bonuses still apply. The timer still ticks down, but that doesn't matter as it will reset back to 25:00:00 when we head back in bounds. Therefore, play the out of bounds sections as safely as possible and minimize your use of weapons (to not lower your weapon bonus later on).
The two weapons that are recommended to use are PSG1 (do not use more than 20 rounds) and the M9 as we'll be heading back in bounds with max ammo anyways.
The following are the areas where you can find loot. Note that some weapon ammo is not worth picking up since you'll be maxed out anyways:
Make sure to pick up Box 1 from Strut A Pump Room otherwise you will not be able to get back in bounds without restarting the level.
Once you've done looting Shell 1, head back to Strut E Parcel Room and use Box 1 on the conveyor belt to teleport to Strut C Dining Hall. This is within the bounds of the level, so the timer and bomb count will reappear on the screen. If you did Door Glitch in Strut B Transformer Room without exiting to the BC Connecting Bridge, then the timer should be at 25:00:00 (will be a little less since its ticking when you're back in the level).
Diffuse the remaining bombs in the level and you should recieve an astronomically high score.
