Wanted Mission (Trench 13, 19)

You'll start off in a somewhat flooded area. Your main objective here is to push forward. Keep an eye out for any ammo or health items scattered around, but don't linger too long.

As you progress, you'll encounter the first enemies in this section. They're usually a type of mutated creature that's resistant to standard gunfire. Aim for weak spots if you can, but don't be afraid to use your strongest weapons if you're overwhelmed. Remember to use your dodge move ([B] + analog stick direction) if they get too close.

There will be sections where you need to swim. Keep an eye on your oxygen meter; running out of air will rapidly deplete your health. Swim efficiently and surface whenever possible.

Watch out for environmental traps or hazards. These could be anything from unstable platforms to pockets of toxic gas. Sometimes these can be used against your enemies, so be observant.

You'll likely find weapon upgrades or new ammo types along the way. Grab them whenever you see them, as you'll need all the firepower you can get.

Pay attention to any clues or hints the game gives you. Sometimes there are hidden paths or alternate routes that can save you time or resources.

The end of the trench will usually lead to a more open area or a transition to the next part of the mission. Be prepared for a potential ambush or a mini-boss encounter as you reach the exit.
