MAKE EVERY
SHOT ECHO.

Guards have 100 HP. Each weapon has independent body damage and time between shots. Head damage uses the shared headshot multiplier. Shotgun shell damage assumes all pellets hit. Guard accuracy and shot intervals modify the selected difficulty. Custom runs have separate records from Standard; all custom mixes share one record.

Weapon drops: walk over your first special weapon to equip it. Matching pickups refill ammunition. Press E near a different weapon to replace your current special weapon; unused ammunition is discarded. 1/2 or wheel switches between pulse and special. Both specials use limited ammunition without reload. Shotgun accuracy counts shells, not individual pellets. At most two drops lie on the ground.
