FU 10 requires stamina for prone shuffling.

Your neon pink weapon charm or glowing backpack will betray you. In FU 10 night crawling, matte black and olive drab are the only colors that exist.

You just killed an enemy. Their body is glowing or lootable. Do not touch it.

When the map goes silent, new players stand up to run. Veterans know: Absolute silence at FU 10 means a predator is holding their breath. Stay down. Wait for the bored enemy to move first.

When you are crawling through tall grass and an enemy steps on your foot, you have 0.3 seconds to react. A suppressed pistol is too slow.
