These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Silent Storm
Breather Level: S2 "Place Marked on the Map" mission is this if you already know what to expect: a ruined house with no enemies and tons of mines before the basement's stairs (the mission objective is some piece of data stored in the basement). You just have to reach the building and throw a powerful-enough grenade in the mined room, which blows the floor and most of the remaining walls. Then, jump in the hole to the basement and pick up the objective. It only requires a couple of minutes.
